REVIEW ARTICLE

Hyperprolactinemia Kusum Lata*, Alka Kriplaniâ€

ABSTRACT Hyperprolactinemia is the most common endocrine disorder of the hypothalamic-pituitary axis. It presents as an ovulatory disorder and is often associated with secondary amenorrhea or oligomenorrhea, galactorrhea and osteopenia. When hyperprolactinemia is confirmed, a cause for the disorder needs to be sought. This involves a careful history and examination, followed by laboratory tests and diagnostic imaging of the sella turcica. Dopamine agonists are the treatment of choice for the majority of patients. Cabergoline has been shown to be more effective and better tolerated than bromocriptine. Transsphenoidal surgery is usually reserved for patients who are intolerant or resistant to dopamine agonists or when hyperprolactinemia is caused by nonprolactin-secreting tumors compressing the pituitary stalk.

Key words: Hyperprolactinemia, hypothalamic-pituitary axis, ovulatory disorder, sella turcica, dopamine agonists

rolactin is a pituitary-derived hormone that plays a pivotal role in a variety of reproductive functions. It negatively modulates the secretion of pituitary hormones responsible for gonadal function, including luteinizing hormone (LH) and folliclestimulating hormone (FSH). Hyperprolactinemia is a condition of elevated prolactin levels in blood which could be physiological, pathological, pharmacological or idiopathic in origin. Management depends on the cause and on the effects it has on the patient. In this review, we summarize advances in our understanding of the clinical significance of hyperprolactinemia and its management.

Regulation of Prolactin Secretion Prolactin is a 198-amino acid protein (23-kd) produced in the lactotroph cells of the anterior pituitary gland.

Its primary function is to enhance breast development during pregnancy and to induce lactation. Prolactin is under dual regulation by hypothalamic hormones delivered through the hypothalamic-pituitary portal circulation. Under most conditions the predominant *Senior Resident †Professor and Head Dept. of Obstetrics and Gynecology AIIMS, New Delhi Address for correspondence Dr Alka Kriplani Professor and Head, Dept. of Obstetrics and Gynecology AIIMS, Ansari Nagar New Delhi 110 029 E-mail: kriplanialka@gmail.com

signal is inhibitory, preventing prolactin release and is mediated by the neurotransmitter dopamine. The stimulatory signal is mediated by the hypothalamic hormone thyrotropin-releasing hormone. The balance between the two signals determines the amount of prolactin released from the anterior pituitary gland and the amount cleared by the kidneys influences the concentration of prolactin in the blood.1,2 Epidemiology The occurrence of clinically apparent hyperprolactinemia depends on the study population and occurs in less than 1% of the general population.3 The rate is higher among patients with specific symptoms that may be attributable to hyperprolactinemia: It is estimated at 9% among women with amenorrhea, 25% among women with galactorrhea and as high as 70% among women with amenorrhea and galactorrhea3 and 17% polycystic ovarian syndrome (PCOS) patients present with hyperprolactinemia. Of these patients, approximately 30% have prolactinsecreting tumors. The prevalence is about 5% among men who present with impotence or infertility.4 Etiology The diagnosis of hyperprolactinemia should be suspected in female patients presenting with oligomenorrhea, amenorrhea, galactorrhea or infertility. Hyperprolactinemia can be physiological or pathological.

Some of the common causes are listed in Table 1.5

REVIEW ARTICLE Prolactinomas account for 25-30% of functioning pituitary tumors and are the most frequent cause of chronic hyperprolactinemia.6 Prolactinomas are divided into two groups: i) Microadenomas (<10 mm), which are more common in premenopausal women and ii) macroadenomas â&#x2030;Ľ10 mm), which are more common in men and postmenopausal women.

Prolonged hypoestrogenism secondary to hyperprolactinemia causes steopenia. Bone loss occurs secondary to hyperprolactinemia-mediated sex steroid attenuation.

Spinal bone density is decreased by approximately 25% in women with hyperprolactinemia10 and is not necessarily restored with normalization of prolactin levels.

Clinical Presentation

The patients can also present with neurological symptoms caused by mass effects of the pituitary tumor. Symptoms include headaches and visual loss such as bitemporal hemianopsia, hypopituitarism, seizures and cerebrospinal fluid rhinorrhea.11

Clinical presentation in women is more obvious and occurs earlier than in men. They typically present with oligomenorrhea, amenorrhea, galactorrhea or infertility.7-9 Galactorrhea is less common in postmenopausal women due to lack of estrogen.

Normal serum prolactin levels vary between 5 and 25 ng/mL in females although physiological and diurnal variations occur.12 Serum prolactin levels are higher in the afternoon than in the morning, and hence should preferably be measured in the morning.

Pituitary

According to Endocrine Society Guidelines for diagnosis and treatment of hyperprolactinemia (The Endocrine Society, 2011), a single measurement of serum prolactin is recommended to establish the diagnosis of hyperprolactinemia; a level above the upper limit of normal confirms the diagnosis as long as the serum sample was obtained without excessive venipuncture stress.13,14

REVIEW ARTICLE large pituitary tumor and a mildly elevated prolactin level, serial dilution of serum samples to eliminate an artifact that can occur with some immunoradiometric assays due to saturation of the capture antibodies is recommended.18 Other Laboratory Studies

Serum thyroid-stimulating hormone (TSH), blood urea nitrogen and creatinine should be done as hypothyroidism and renal failure are the two common causes of increased prolactin.

Pregnancy should always be excluded unless the patient is postmenopausal or has had a hysterectomy.

In addition, hyperprolactinemia is a normal finding in the postpartum period.

Role of Imaging

Any patient who has hyperprolactinemia without an identified cause requires imaging of the hypothalamicpituitary area. A mildly elevated serum prolactin level may be due to a nonfunctioning pituitary adenoma or craniopharyngioma compressing the pituitary stalk, although prolactin levels that are very high (>250 ng/mL) are almost always associated with a prolactinoma.3 Magnetic resonance imaging (MRI) with gadolinium enhancement provides the best visualization of the sellar area.

Management The treatment of hyperprolactinemia depends on the underlying causes, natural course of the disease and the aim of treatment. The goals of treatment for are: • Normalization of prolactin level • Restoration of gonadal function and fertility • Avoidance of the adverse effects of chronic hyperprolactinemia like osteoporosis.

An additional goal of treatment in macroprolactinoma patients is tumor shrinkage with relief of mass symptoms. Current therapeutic options include medical therapy, surgery and radiotherapy.

Management of Drug-Induced Hyperprolactinemia Although hyperprolactinemia commonly occurs with psychotropic medication use, only a minority of Asian Journal of Obs and Gynae Practice, Vol. 1, January-March 2014

patients-typically those with hypogonadism need to be considered for treatment. After a work-up to rule out alternative causes of hyperprolactinemia and bone density measurement, gonadal steroid replacement should be considered to preserve skeletal health and maintain compliance with a successful psychiatric medication regimen. The treating psychiatrist should be consulted for any change in psychotropic regimen.

Whether to treat a patient who has antipsychoticinduced hyperprolactinemia with a dopamine agonist remains controversial. Some studies suggest that dopamine agonist therapy will normalize prolactin levels in only up to 75% of such patients but may lead to exacerbation of the underlying psychosis.19-22 Medical Therapy Dopamine agonists like bromocriptine and cabergoline have become the treatment of choice for the majority of patients with hyperprolactinemia.

Bromocriptine was the first dopamine agonist to be introduced into clinical practice. It is a semisynthetic ergot derivative of ergoline, a D2 receptor agonist with antagonist properties at D1 receptors. Its half-life is relatively short and has to be taken 2 or 3 times daily.23 It is effective in normalizing serum prolactin levels and restoring gonadal function in 80-90% of patients, with varying degrees of tumor size reduction.24 The most common adverse effects are nausea, vomiting and headache (up to 60% of patients). Postural hypotension is common especially when initiating therapy and can result in dizziness (25%). Other side effects include a Raynaud-type syndrome of painless digital vasospasm, drowsiness, fatigue, leg cramps, insomnia, blurred vision and paresthesia.23,25 Side effects can usually be minimized by introducing the drug at a very low dosage (0.625 or 1.25 mg/d), taking the tablets with food and by very gradual dose escalation. Therapeutic dosages are generally in the range of 2.5-15 mg/day in hyperprolactinemic patients, but 5-17%26 of patients are found to be resistant, requiring dose up to 30 mg/day.23 Another alternative to oral treatment is vaginal usage of the same drug which is well-tolerated. Vaginal absorption is nearly complete and first pass metabolism in liver is avoided allowing lower therapeutic dosing.27 It is also available in a long acting form (depot‑bromocriptine) for intramuscular injection and a slow release oral 9

REVIEW ARTICLE form.28,29

When to Discontinue Therapy

Cabergoline is an ergoline derivative with high affinity and selectivity for the D2 receptor. It has an extremely long plasma half-life of about 65 hours allowing onceor twice-weekly administration. It has been shown to achieve normal serum prolactin levels in 85-86% and restoration of normal gonadal function in 90-91%.30,31

Four recent studies33-36 suggest that in a subset of patients, dopamine agonist withdrawal may be safely undertaken after 2 years in patients who have achieved normoprolactinemia and significant tumor volume reduction. The risk of recurrence after withdrawal ranges from 26% to 69% and all studies have shown that recurrence is predicted by prolactin levels at diagnosis and by tumor size.

Cabergoline and bromocriptine have been compared in a multicenter collaborative study involving 459 women with hyperprolactinemic amenorrhea.25 Stable normoprolactinemia was achieved in 186 of the 223 (83%) women in the cabergoline group compared with 138 of 236 (59%) women in the bromocriptine group (p < 0.001), and resumption of ovulatory cycles or pregnancy occurred in 72 and 52%, respectively (p < 0.001).

Cabergoline, is more effective and causes fewer adverse effects than bromocriptine. However, it is much more expensive and is often used in patients who cannot tolerate the adverse effects of bromocriptine or in those who do not respond to bromocriptine.

Therapy should be continued for approximately 12-24 months (depending on the degree of symptoms or tumor size) and then withdrawn if prolactin levels have returned to the normal range. After withdrawal, approximately one-sixth of patients maintain normal prolactin levels. Response to therapy should be monitored by checking fasting serum prolactin levels and checking tumor size with MRI. Most women (approximately 90%) regain cyclic menstruation and achieve resolution of galactorrhea.

Management of Prolactinoma

Cabergoline is considered to have higher efficacy in normalizing prolactin levels and pituitary tumor shrinkage. In a placebo-controlled study, cabergoline treatment (0.125-1.0 mg twice-weekly) for 12-24 months in patients harboring prolactinsecreting microadenomas resulted in normalization of prolactin levels in 95% of patients. Cabergoline restored menses in 82% of women with amenorrhea.32 In a retrospective study of 455 patients, cabergoline normalized prolactin levels in 92% of patients with idiopathic hyperprolactinemia or a microprolactinoma and in 77% of 181 patients with macroadenomas.31

For patients who after 2 years of therapy have achieved normal prolactin levels and no visible tumor remnant and for whom dopamine agonists have been tapered or discontinued, follow-up includes: 1) Measurement of serum prolactin levels every 3 months for the first year and then annually thereafter; and 2) MRI if prolactin increases above normal levels.34 In women with microprolactinomas, it may be possible to discontinue dopaminergic therapy when menopause occurs.

Surgery General indications for pituitary surgery include patient drug intolerance, tumors resistant to medical therapy, persistent visual-field defects in spite of medical treatment and patients with large cystic or hemorrhagic tumors. Transnasal transsphenoidal microsurgical excision of prolactinoma is the procedure of choice. Hyperprolactinemia recurred within 5 years after surgery in about 50% of patients with microprolactinomas who were initially thought to be cured.37 Re-evaluation of long-term results indicates a success rate of about 75% for surgical removal of microprolactinoma. However, the results of surgery for macroprolactinoma are poor, with a long-term success rate of only 26%.38 Radiotherapy should be reserved for resistant or malignant prolactinomas. Normalization of hyperprolactinemia occurs in approximately one-third of patients treated with radiation. Radiation therapy is associated with side effects including hypopituitarism and rarely, cranial nerve damage or second tumor formation.39 Conclusion Once diagnosis of hyperprolactinemia is confirmed the underlying cause of the disorder needs to be determined and common causes like hypothyroidism

CLINICAL STUDY

Evaluation of Perinatal Outcome by Antenatal CTG and Umbilical Artery Doppler in Pre-eclamptic Mothers Barunoday Chakraborty*, Tamal Kumar Mondal†, Sannyasi Charan Barman‡, Biswa Pratim Rudra#, Ramkrishna Sahana§, Prabhat Chandra Mondal§

ABSTRACT This was a well-controlled hospital-based longitudinal prospective randomized study with a sole focus on pre-eclampsia cases, where cardiotocography (CTG) and colored Doppler were the two special investigative tools applied to examine the perinatal outcome. The study concluded with a note that antenatal CTG is a useful objective test to know the intrauterine fetal status but it cannot forecast the fetal behavior during labor, neither does it provide a guide to optimize the timing of induction of labor (IOL) or termination by cesarean section. Color Doppler indices done after 34 weeks definitely give a qualitative assessment of fetoplacental perfusion but it cannot predict the said perfusion during labor - when there occurs a degree of compromise with the uterus contracting repetitively. Ultrasonography (USG) for fetal biometry and liquor volume is a good test to determine small for gestational age or intrauterine growth restriction (IUGR) as the case may be taking cognizance of other factors e.g., pre-eclampsia, fetal congenital anomaly, etc. Every mother with pre-eclampsia needs to be evaluated both clinically, biochemically and ultrasonologically. Understanding the limitation of antenatal CTG and color Doppler indices, these should be applied in a few selected cases e.g., increased fetal movement, IUGR, which is reassuring to both the patient and the doctor who can wait till a reasonable degree of fetal maturity occurs before one goes for IOL or a cesarean section.

Patients with a suspicious CTG should undergo continuous CTG during labor - otherwise there is always a tendency to go for an early lower-segment cesarean section (LSCS). For a pre-eclamptic mother with a pathological CTG the decision is an elective LSCS; whereas, cases with pathological CTG but normal Doppler indices the judgment is too difficult. The answer then would lie on factors like whether the pre-eclampsia is controlled and whether the biochemical and hematological parameters are within normal limits. Of course thanks to the presence of a special newborn care unit (SNCU) nearby.

Key words: CTG, Doppler, pre-eclampsia

Introduction, Review of Literature and Objectives Pre-eclampsia is a multisystem, highly variable disorder, unique to pregnancy and a leading cause of maternal and perinatal mortality and morbidity.1,2 It is a syndrome defined by hypertension and proteinuria that also may be associated with a myriad of other signs and symptoms such as edema, *Associate Professor Dept. of Obstetrics and Gynecology BS Medical College, Bankura, West Bengal † Resident Dept. of Obstetrics and Gynecology RG Kar Medical College, Kolkata ‡ RMO-cum Clinical Tutor # Senior Resident § Assistant Professor Dept. of Obstetrics and Gynecology BS Medical College, Bankura, West Bengal Address for correspondence Dr Barunoday Chakraborty G5/26, College Quarter, BS Medical College, Gobinda Nagar Bankura, West Bengal -722 102 E-mail: asmp80@rediffmail.com

visual disturbances, headache and epigastric pain.3 The increased incidence of perinatal morbidity and mortality seen in pregnancies complicated by preeclampsia is primarily due to the need for premature delivery and uteroplacental insufficiency resulting in a compromised blood flow to the fetus.4 The primary adoptive response of the fetus to placental insufficiency is a decrease in growth. Persistent placental insufficiency will result in decreased fetal movement to conserve energy, hemodynamic redistribution to favor the oxygenation of organs critical to the economy such as the brain, heart, suprarenal and attempt to improve the efficiency of the placental gas exchange by increasing the heart rate and the synthesis of red cells. Progressive decompensation like this will lead to a metabolic and respiratory acidosis, increased impedance to fetoplacental circulation, renal insufficiency with decreased amniotic fluid volume; myocardial compromise, absent or reversed atrial flow in ductus venosus, late deceleration in the fetal heart rate (FHR) tracing and fetal death. It would be ideal that this sequence of pathological changes elicited

11

CLINICAL STUDY by placental insufficiency and fetal hypoxia could be identified in each of its different stages by a single test, which has not been achieved so far.

In an attempt to stratify risk, a variety of antepartum screening tests are performed, which include few laboratory tests and sonographic assessments, besides history taking and clinical examination including serial symphysiofundal height measurement. Antenatal cardiotocography (CTG) is a special test for evaluation of fetal status. Prof. Essar GS Dows and Prof. C Redman of United Kingdom were two pioneers in the eighties who devised the computer program to evaluate CTG. The basic objective of CTG is to assess co-ordination between fetal central nervous system (CNS) and the cardiovascular system based on the fact that a well-oxygenated healthy fetus with functionally intact CNS-cardiac axis will show accelerations (rise of FHR 15 beats/minutes for 15 seconds above baseline) with fetal movements - the so called reactive CTG. In addition, good FHR variability (â&#x2030;Ľ5 bpm) suggest normal balance of sympathetic-parasympathetic activity, an indirect evidence of adequate oxygenation of fetal regulatory centers; indeed, a normal FHR variability is the hallmark of fetal well-being. Accepted normal parameters for term fetus are: zz Baseline FHR 110-160 beats/minute zz Baseline variability should be >5 beats/minute zz Presence of two or more accelerations of FHR exceeding 15 beats/minute, sustained for at least 15 seconds in a 20-minute period. This pattern is termed as â&#x20AC;&#x2DC;Reactive.â&#x20AC;&#x2122; zz Absence of deceleration.

However, the Cochrane meta-analysis of randomized controlled trials (RCTs) involving 1,558 high/ intermediate risk pregnancies suggests antepartum CTG alone has no significant impact on perinatal outcome.5 Though, initial studies have shown a strong correlation between abnormal CTG and poor perinatal outcome,6 when CTG is used alone significant interobserver variations, poor specificity and high false-positive rates causing increased number of lower-segment cesarean section (LSCS) are other problems.

The change in behavior of ultrasound waveform reflecting from a moving object - the Doppler effect was introduced in the assessment of umbilical artery 12

flow at Dubling in 1977. Longitudinal Doppler studies of the umbilical artery show that the systolic/diastolic (S/D) ratio decreases as gestation progresses. This is an indirect evidence of decreasing placental resistance with advancing gestation.7 However, there is no definite agreement as to what constitutes an abnormal Doppler study. Most authors have accepted as S/D ratio >3.0 as the cut-off beyond 30 weeks gestation.

Gradual increase in umbilical artery resistance leads to absent and subsequently reversed end-diastolic flow, which is associated with progressively worse perinatal outcome. The Doppler indices are calculated as ratios between peak systolic velocity (A), end-diastolic peak velocity (B) and mean velocity (mean). The indices most common in clinical practice, are pulsatility index (PI) = (A-B)/mean, and resistant index (RI) = (A-B)/A. With normal placental perfusion, the umbilical artery waveform has a pattern compatible with a low-resistance system displaying forward blood flow throughout the cardiac cycle.8 Inadequate placental perfusion causes progressive changes in the Doppler flow pattern of umbilical artery starting from absent or reversed end-diastolic flow, increase in resistance index, which correlate well with fetal acidosis.9 The first meta-analysis of umbilical artery Doppler in high-risk pregnancies published in 1995 demonstrated significant reduction in perinatal death.10 Two large RCTs- one from South Africa and other from Canada, and one Cochrane review of routine Doppler studies of umbilical artery in high-risk pregnancies have shown conflicting reports of benefit regarding perinatal outcome. However, evidence from small RCTs does indicate less requirement of emergency cesarean section for fetal distress if Doppler velocity was used (NICE Guideline, 2010). The ongoing TRUFFLE study has been designed to compare reduced short-term variations on CTG and Doppler velocimetry of ductus venosus to determine optimum timing of delivery of growth restricted fetus.11 In this study, spanning six months we tried to evaluate perinatal outcome in pre-eclampsia in term of mode of delivery (vaginal/instrumental/LSCS), need for induction of labor (IOL), neonatal status according to specific parameters by means of antenatal CTG and umbilical artery Doppler in late third trimester at our institution, which is a tertiary maternity care center with an annual delivery rate of >20,000, delivering optimal care free of cost to a large population from three districts namely Bankura, Purulia and Paschim Medinipur in West Bengal. Our objective Asian Journal of Obs and Gynae Practice, Vol. 1, January-March 2014

CLINICAL STUDY was to ascertain an optimum and cost-effective way to treat pre-eclamptic mothers and to obviate special investigations like CTG and umbilical artery Doppler in each and every case and thereby save some cost as well as manpower.

Material and Methods This was a prospective longitudinal study carried out in our department during 6 months period from April 2012 to September 2012. All pre-eclamptic mothers of >34 weeks of gestation with a single intrauterine fetus presenting cephalic presentation without any congenital anomaly were included in the study. Patients with prelabor rupture of membrane, antepartum hemorrhage (APH), bad obstetric history, elderly primi (>35 years), multifetal pregnancy, malpresentation, history of systemic illness e.g., antiphospholipid syndrome, chronic renal disease, heart diseases, psychiatric illness were excluded.

Known cases of pre-eclampsia were evaluated with history, examination and laboratory investigations including urine albumin, serum uric acid, platelet count, clotting time, renal and liver function tests.

The cases were then randomized and allocated in the study group and control group. The study group had undergone an antenatal CTG for 40 minutes and umbilical artery Doppler study. Categorization of FHR traces was done following Royal College of Obstetricians and Gynecologist (RCOG) criteria 2001

as normal, suspicious and pathological. Normal implied a fetal well-being and as such a conservative approach; whereas, suspicious implied continued observation and additional test e.g., vibroacoustic stimulation (VAS) and pathological indicated an urgent delivery.

The study group had also undergone assessment of fetoplacental profile and a Doppler assessment of umbilical artery. S/D ≤3 and RI ≤0.6 were considered normal; raised indices, absent or reversed end-diastolic flows were taken as signs of fetal distress.

The decision to deliver the baby at an optimum time through an appropriate route (vaginal/LSCS) was taken considering the gestational age and the results of CTG and umbilical artery Doppler indices.

The control group was followed up by daily clinical monitoring and routine USG for fetoplacental profile and liquor volume. They were delivered by appropriate route at an optimum gestational age according to these findings and consultant decision.

Study group, where a conservative approach was taken till maturity (37 weeks) were followed up by twice in a week CTG and another Doppler study after 2 weeks. Control group, in similar situation had another routine USG for FPP after 2 weeks. The neonatal outcomes of both groups were recorded in predesigned proforma and compared using Chi-square test and

Observations and Discussion Two-third of our study population (n = 35) had a reactive CTG and one-third showed a nonreactive type (Table 1). Nearly, 92 patients of reactive CTG against 45% of those with nonreactive type had a 14

normal delivery and 56% with nonreactive CTG had a cesarean delivery against only 3% of reactive type - the difference of picture is definitely significant (p < 0.05). Random application of CTG has increased the number of LSCS whenever CTG tracing gets abnormal has been supported by other authors in the past: Khursheed et al showed a 72% LSCS rate when CTG was of pathological pattern.12 Overall, the incidence of vaginal delivery (normal and instrumental) among the study group was 80% Asian Journal of Obs and Gynae Practice, Vol. 1, January-March 2014

(28 out of 35) and LSCS was 20%. In a tertiary care center 20% LSCS rate among pre-eclampsia cases was quite acceptable against World Health Organization (WHO) standard of 15%. So, CTG in this study has favored decision towards cesarean section but it has not pushed the number to an unacceptably high rate, which needed an audit. The message here is that CTG in pre-eclampsia is an useful investigation that allows judicious decision making and does not cause unnecessary panic among obstetricians to take hasty decisions of LSCS, which is obvious from the fact that 44% (5 out of 11) of nonreactive CTG cases were allowed a normal delivery. Though, a significantly higher incidence (p = 0.003) of low Apgar score was noted among nonreactive CTG, there was no perinatal death. Similar findings of increased neonatal hypoxia were noted by Khursheed and Chew et al in 2009.13 So, CTG can predict a low Apgar neonate but not enough to predict a perinatal death.

More than two-third (25 out of 35, Table 2) of the study group had high umbilical artery Doppler indices (Table 2) but incidence of LSCS was not significantly higher (p = 0.24). However, among the neonates the low Apgar score was significantly associated with raised Doppler indices, 52% against 10% (p = 0.01): (Fig. 1). This finding validates the fact that umbilical artery Doppler shows the extent of fetoplacental perfusion during fetal diastole and is a recognized Asian Journal of Obs and Gynae Practice, Vol. 1, January-March 2014

tool to show intrauterine fetal status. Sharma et al got almost similar findings in their study in 2010.14 The mean gestational age at birth of the study group and control group were not statistically different (p = 0.792). The labor events; the incidence of IOL versus spontaneous onset labor, incidence of vaginal delivery versus LSCS; Apgar score at 1 minute and 5 minutes; mean neonatal birth weight, number of hypoxic neonates requiring Bag Mask (BM) resuscitation and special newborn care unit (SNCU) admission when compared vis-a-vis with the control group had shown quite similar results with p value ranging from 0.125 to 0.816 (Table 3). A range of well-defined studies including one evidence-based meta-analysis from 1992 to 2001 could find no significant difference in neonatal outcome and LSCS rate with Doppler velocimetry.15 In 2010, Alfirevic et al in a Cochrane review on “Fetal and umbilical Doppler ultrasound in high-risk pregnancies” could not identify a difference in the requirement of intubation and assisted ventilation among neonates between Doppler velocimetry group and control group withou Doppler velocimetry.16 Conclusion Therefore, universal application of antenatal CTG and umbilical artery Doppler does not do anything better than a routine USG among mature fetuses to forecast perinatal outcome. It is the labor monitoring and 24 hours cesarean section facility that matters when emergency arises in the form of prolonged labor, meconium staining and fetal bradycardia. Over the years, scientists have explored this area to determine the postnatal events with antenatal CTG and Doppler, which has remained a grey area even today because beyond 34-36 weeks of gestation, it is uncommon to find absent or reversed EDF in the umbilical arteries caused by uteroplacental insufficiency. Abnormal umbilical artery Doppler after 35 weeks should prompt consideration of other causes specially aneuploidy (Trisomies 18, 21).

In absence of aneuploidy assessment of intrauterine growth restriction (IUGR) in late pregnancy is challenging because umbilical artery Doppler has a limited value in this setting. The timing of delivery is contentions because a favorable perinatal outcome is expected even with early delivery once diagnosis of IUGR has been made by fetal ultrasound biometry, 15

CLINICAL STUDY amniotic fluid index, umbilical and middle cerebral artery Doppler indices. Elective induction of labor with continuous FHR monitoring may result in successful vaginal delivery although fetal distress and meconium staining in labor are common complications. No study exist to provide recommendation in these circumstances regarding early delivery versus antepartum monitoring and delayed delivery.17 The current study though conducted on a small sample can be considered as a pamphlet that speaks the need of careful clinical monitoring along with a routine USG after 34 weeks thanks to the presence of SNCU attached to the maternity ward. Control of blood pressure by labetalol or nifedipine (both the drugs are freely available at our ward); sending blood samples for Hb%, hematocrit, platelet count, serum urate, liver enzymes and 24 hours urine for protein; with or without the presence of IUGR on USG provide valuable clue to choose between immediate delivery by LSCS; IOL followed by fetal monitoring and trial of labor for at least 6 hours and/or prophylactic MgSO4 injection followed by emergency LSCS.

CLINICAL STUDY

A Study on Correlation of Menstrual Pattern and Histopathology of Uterine Endometrium in Reproductive Age Groups of Women with Hypothyroidism Amitava Pal*, Arindam Rakshit†, Rupali Modak‡, Ganesh Chandra Hati#

ABSTRACT Objectives: To determine the correlation between histopathological findings of endometrium with the menstrual patterns of hypothyroid women and to compare with the euthyroid women. Material and methods: The hospital-based crosssectional study was conducted in the Dept. of Obstetrics and Gynecology, Burdwan Medical College, Bardhaman over 1 year from February 2010 to January 2011. Forty-six patients with abnormal uterine bleeding in the reproductive age groups (15-45 years) were evaluated for thyroid profile and subsequently dilation and curettage (D&C) operation was undertaken in OT. All the women were without organic lesion detectable either clinically or by imaging studies. Among this study population, 24 cases having low free thyroxine (FT4) and increased thyroid-stimulating hormone (TSH) level above the normal reference range (serum TSH is 0.8-5 µIU/mL and FT4 is 0.8-2 ng/dL) were designated as study group and the remaining 22 with normal thyroid profile were taken as control. Statistical analysis was performed by Student’s t-test and Chi-square test. A p value <0.05 was considered statistically significant. Results: Metrorrhagia (33.33%) and oligomenorrhea (33.33%) were two frequent symptoms in hypothyroid patients, but menorrhagia (54.54%) was the leading presentation in euthyroid women (p < 0.040).

Normal cycle was noted only in three (12.50%) hypothyroid women and remaining 21 (87.50%) had functional disturbances.

Functional disturbances were more common finding in hypothyroid groups of women. Metrorrhagic patient had more functional problem (81.82%; 9/11), which signify more chances of endometrial disturbances. Women with oligomenorrhea had no ovulatory disturbances. No specific difference between menstrual pattern and endometrial morphology was noted between case and control groups. Conclusion: Metrorrhagia and oligomenorrhea were the common menstrual abnormalities in hypothyroid women and functional disturbances in the form of anovulation were the most frequent histopathological feature.

irregular shedding of the endometrium.3 Irregular shedding of endometrium is a clinicopathological entity characterized by prolonged and profuse menstrual flow coupled with pathological findings of a mixture of secretory, regressing, dissociating and regenerative endometrium. The disordered proliferative endometrium observed as a consequence of anovulatory cycle is a histological abnormal endometrium for unopposed estrogen action. In contrast to normal proliferative form it is nonuniform and often merges with hyperplasia. Endometrial hyperplasia is a heterogeneous group of lesions characterized by abnormal proliferation of glands and stroma, with predominating glandular component. It may be simple nonatypical, complex nonatypical, simple atypical and complex atypical. Some of these hyperplastic lesions are reversible and some may progress to neoplasia or may be truly neoplastic.

The objective of this study was to evaluate the endometrial histopathological pattern in hypothyroid patients in childbearing age groups and also to ascertain the correlation between histopathological findings and Asian Journal of Obs and Gynae Practice, Vol. 1, January-March 2014

CLINICAL STUDY different menstrual irregularities in both euthyroid and hypothyroid women.

Material and Methods The present hospital-based cross-sectional study was undertaken in the Dept. of Obstetrics and Gynecology, Burdwan Medical College, Bardhman in collaboration with the Dept. of Pathology and Biochemistry of the same institution from February 2010 to January 2011. The study was approved by Institutional Review Board and Ethics Committee. Forty-six women with abnormal uterine bleeding during the study period of 1 year were evaluated. All of them were without any obvious organic lesion detectable either clinically or imaging studies. Among the study population, 24 had decreased free thyroxine (FT4) or increased thyroid-stimulating hormone (TSH) level above the normal reference range and were designated as hypothyroid women (cases). Remaining 22 had normal thyroid profile and they were considered as control. Patients with the history of contraceptive use, wearing intraceterine contraceptive device (IUCD) and taking progesterone for their bleeding just prior to dilation and curettage (D&C), clinically detectable or ultrasonography (USG) proved organic lesion and amenorrhea or amenorrhea followed by bleeding per vagina with positive pregnancy test were excluded from our study. In the study group, three patients had primary infertility along with menstrual irregularity and one case had hypothyroidism.

Demographic variables, such as maternal age, parity, complaints at admission, clinical findings were evaluated.

Relevant investigations included Hb%, platelet count, other coagulation profile and pregnancy test. Imaging study was undertaken to evaluate organic pathology in abnormal uterine bleeding. Biochemical evaluation of thyroid hormone profile like FT4 and TSH was done in all cases by commercially available kit. Normal reference range of serum TSH is 0.8-5 µIU/mL and FT4 is 0.8-2 ng/dL. Following D&C, the endometrial tissue material was sent for processing, sectioning and staining for histopathological examination. The tissue material was categorized histopathologically under microscope by low- and high-power magnification as normal endometrium and functional disturbance of endometrium, which included ovulatory disturbances (irregular shedding) and anovulatory disturbances (disordered proliferative endometrium and hyperplastic Asian Journal of Obs and Gynae Practice, Vol. 1, January-March 2014

proliferative endometrium).

Statistical analysis was performed by Student’s t-test and Chi-square test. All analysis was performed by SPSS software version 16. The p value <0.05 was considered statistically significant.

Results Table 1 summarizes the patient profile. Between the two groups of variables, age and parity did not show any statistical significance but FT4 and TSH level of hypothyroid female showed statistically significant difference (p < 0.0001) when compared to euthyroid women.

Table 2 shows the menstrual pattern in both the groups.

endometrium and four had hyperplastic proliferative type of endometrium and no ovulatory disturbance was noted. Both the cases of polymenorrhea had hyperplastic proliferative endometrium.

Discussion A total of 46 women (study group - 24; control group - 22) were included. Apart from meticulous history and clinical examination, relevant investigations especially histopathological features of endometrium were categorized along with the level of thyroid hormone status followed by correlation in both the groups.

The mean age of hypothyroid and euthyroid women were 30.917 years and 30.591 years, respectively and the mean parity were of 2.04 and 2.00. Joshi and Despande4 reported that 62.9% of clinically suspected dysfunctional uterine bleeding (DUB) cases were in the age groups of 15-44 years and majority of them were multipara, but Rosario reported a relatively higher incidence (97%) in multipara.5 The present study included only the women in the reproductive age groups. Metrorrhagia and oligomenorrhea were two frequent symptoms in the hypothyroid women in our series, but most of the studies found correlation between menorrhagia and oligomenorrhea in the same group of women.6-8 Moragianni et al demonstrated the importance of thyroid profile evaluation in patients Asian Journal of Obs and Gynae Practice, Vol. 1, January-March 2014

who presented with menorrhagia9 and it would not be surprising if in a proportion of women with menorrhagia, hypothyroidism clinical-or subclinical often coexists.8 The incidence of polymenorrhea and menometrorrhagia were very low (4.2% each) in our study. Polymenorrhea (2.7%) was also designated as the least common type of menstrual disorder described in many reports.10,11 Hypothyroid women usually are associated with abnormal menstrual cycle due to anovulation and our study found anovulatory cycle in 66.66% of cases. Krassas7 in his study also noted that hypothyroidism is commonly associated with the failure of ovulation. So, in anovulatory cycle due to estrogen dominance there will be prolonged proliferation or disordered proliferation or hyperplasia. Mansfield et al12 reported the same histopathological finding in the anovulatory cycle. Specific mention should be made about disordered proliferation of endometrium, which some would include within hyperplasia as it lacks increased ratio of glands to stroma, which otherwise characterizes hyperplasia. In the present study, no correlation was noted between menorrhagia and subsequent histopathologic category. Pilli et al, also did not find any correlations.11 Metrorrhagic patient hads more functional problems (81.82%; 9/11), which signify more chances of endometrial disturbances. Ovular oligomenorrhea was rare in the present series and our finding was inconsistent with the observations of Dutta et al.13 No significant endometrial histopathological correlation could be made in cases of polymenorrhea, menometrorrhagia and hypoamenorrhea followed by heavy bleeding because of small sample size.

Conclusion In hypothyroid women, the common menstrual abnormalities were metrorrhagia and oligomenorrhea.

Functional disturbance in the form of anovulation was the most frequent histopathological finding. No definite correlation was noted between menorrhagia and histology of endometrial sample in hypothyroid women. In metrorrhagic bleeding pattern incidence of abnormal endometrial histopathology was very high, but ovular oligomenorrhea was a rare finding.

and drug intake should be ruled out. Medical therapy is the mainstay of treatment in most of the women with surgery being reserved for patients who are unresponsive to medical therapy. Cabergoline, which has a long half-life allowing once-or twice weekly dosing, and a better tolerability profile, has become the dopamine agonist of choice and for management of pituitary adenomas multidisciplinary approach is needed.

CLINICAL STUDY

A Comparative Study to Analyze the Association of Metabolic Syndrome in Females with Diagnosed Polycystic Ovarian Syndrome Richa Singh*, Saroj Singh*, Poonam Yadav†, Harpreet Kaur‡

ABSTRACT Objectives: Polycystic ovarian syndrome (PCOS) is a common female endocrinopathy affecting 5-6% of women within the age group 12-45 years. This study was contemplated with the aim to study the prevalence of metabolic syndrome in patients of PCOS and to study the spectrum of clinical features of metabolic syndrome in patients of PCOS. Material and methods: This case-controlled study was conducted on 50 cases of diagnosed PCOS females and compared with 50 healthy age and body mass index (BMI) matched controls. Results: The prevalence of metabolic syndrome in PCOS patients was found to be 24% and in control group it was 6%. Among patients with metabolic syndrome 14% of patients had high blood pressure, 12% had impaired fasting glucose, 38% have high waist-hip ratio, 14% have raised serum triglycerides and 44% had decreased high-density lipoprotien (HDL). Conclusion: It is observed that metabolic syndrome manifests at an early age in women with PCOS. In order to prevent metabolic syndrome one should maintain BMI <25 and waist circumference <35 inches.

Key words: Metabolic syndrome, polycystic ovarian syndrome, hyperinsulinemia

P

olycystic ovarian syndrome (PCOS) is one of the most common female endocrinopathy affecting 5-6% of women within the age group 12-45 years.

These patients are at high-risk of developing infertility, dysfunctional uterine bleeding, endometrial carcinoma and a number of metabolic disorders including insulin resistance, hyperinsulinemia, type 2 diabetes mellitus, hypertension, dyslipidemia and cardiovascular disease.

Due to these facts, early diagnosis of the syndrome should be emphasized.

This background knowledge demands the necessity to work out the prevalence of metabolic syndrome in women with PCOS in our society and to measure the strength of their association in the Indian scenario.

Material and Methods This study was conducted on 50 cases of diagnosed PCOS coming to our hospital and was compared with 50 healthy age and body mass index (BMI) matched women (control group) over a period of 1 year.

Inclusion Criteria

Around 50 cases diagnosed to have PCOS by the Rotterdam European Society of Human Reproduction Embryology/The American Society of Reproductive Medicine (ESHRE/ASRM) PCOS group’s revised 2003 criteria, with presence of any two of the three criteria, were recruited for the study. These criteria are:

Aims and Objectives • To study the prevalence of metabolic syndrome in patients of PCOS.

• Oligo and/or anovulation

• To study the spectrum of clinical features of metabolic syndrome in patients of PCOS.

• Polycystic ovaries (as confirmed by USG)

• Clinical and/or biochemical signs of hyperandrogenism

The criteria for metabolic syndrome in women with PCOS. According to National Cholesterol Education Program (NCEP), Adult Treatment Panel III (ATP III) 2001.

Three out of these five will qualify for the syndrome • Abdominal obesity (waist circumference ≥88 cm or 35 inches) and ≥80 cm for Asian females.

• Triglycerides ≥150 mg/dL 25

CLINICAL STUDY • High-density lipoprotein (HDL) cholesterol ≤50 mg/dL

Table 5. Table 6 shows that the prevalence of metabolic syndrome in various studies.

• Blood pressure ≥130/85 mmHg

Discussion

• Fasting plasma glucose ≥100 mg/dL or previously diagnosed type 2 diabetes.

After taking careful history from the patient and conducting examination, following investigations were carried out - hemogram, fasting blood sugar, oral glucose tolerance test (OGTT), fasting insulin, fasting lipid profile, hormonal estimations for leuteinizing hormone, follicle-stimulating hormone, testosterone, estrogen, progesterone and ultrasound abdomen.

In these women fasting blood was drawn for glucose, insulin and lipid profile, which included triglycerides, total cholesterol, HDL and low-density lipoprotein (LDL) cholesterol. A 2-hour 75 g glucose tolerance test was done in all PCOS patients.

Two markers for obesity, such as BMI and waist-hip ratio, which depicts central obesity were used to study relationship of obesity to lipid parameters. Height (m) and weight (kg) measurements can be used to calculate the BMI (BMI = Weight in kg/height in m2). Waist-hip ratio can be calculated after measuring waist circumference between pelvic brim and costal margin, while hip circumference is taken at the level of the greater trochanter. Waist-hip ratio >0.85 is considered abnormal, while <0.85 normal.

The results were subjected to statistical analysis wherever applicable.

Results The profile of patients include in the study is shown in Table 1. The distribution of cases and controls according to BMI (kg/m2) is shown in Table 2.

26

This was a cross-sectional case-control study of 100 females attending our OPD over a period of 1 year.

If we compare BMI matched cases and controls, then also lipid profile derangement is associated more with PCOS obese than non-PCOS obese (p < 0.04). This is in accordance with the study of Macut et al5 who found that overweight and normal weight women with PCOS have higher incidence of lipid profile derangement than their controls. Wild et al6 found that dyslipidemia is more common in PCOS. In our study among patients with lipid profile derangement, 44% had decreased HDL as compared Table 1. Patient Profile Age group 15-25

to 12% of control (p < 0.05). Low HDL is having more detrimental effect on lipid profile derangement predictions among cases, which is in accordance with a study in Teharian women by Mohini et al,7 where

Asian Journal of Obs and Gynae Practice, Vol. 1, January-March 2014

low HDL was found in 96.9% of cases of metabolic syndrome in PCOS. Study by Dey et al2 showed deceased HDL in 50% cases.

In our study, waist circumference, which depicts central obesity ≥80 cm was found in 38% of cases and 14% of controls (p < 0.05). It is different from the study done

by Ehrmnn et al,3 which supports high value of waist circumference by citing 80% of subjects above 88 cm.

In our study, fasting insulin level showed increase in 24% of cases and 10% of control (p < 0.05) it shows a significant difference among women with metabolic syndrome in comparison to those without metabolic syndrome as supported by Dokras et al4 study in 2005.

We observed that, while USA women and Indian women have similar androgen levels, similar blood pressure, similar total cholesterol and LDL, USA women have higher body weight, higher fasting insulin, higher fasting glucose level, lower HDL and raised triglycerides.

Most of these difference occurred as a result of higher prevalence of obesity in USA group but, other factors including characteristics of diet may also be responsible.

Thus, in our study prevalence of metabolic syndrome is 24% among cases and 6% among age and BMI matched controls, which shows a statistically significant difference (p < 0.05) and thus PCOS per se is responsible for prevalence of metabolic syndrome.

Conclusion It is observed that metabolic syndrome manifests at an early age in women PCOS. Hyperinsulinemia, a central factor in the pathogenesis of PCOS, also appears to be a critical link between PCOS and MBS. Thus, there is an urgent necessity to assess the rising trend of metabolic syndrome among the women with PCOS and to take early measures for primary prevention of its long-term-sequel.

In order to prevent metabolic syndrome maintain BMI <25 and waist circumference <35 inches to prevent the development of metabolic syndrome or candiovascular disease.

An independent panel convened by the National Institutes of Health has recommended that well-designed, multicentric studies be conducted to determine factors such as obesity, that exacerbate a genetic predisposition.

The panel also determined the need for additional

CLINICAL STUDY research to identify risks and treatments for complications and how to manage the common symptoms.

CLINICAL STUDY

Comparison of Laparoscopic-Assisted Vaginal Hysterectomy and Nondescent Vaginal Hysterectomy: A Retrospective Study Geeta Jain*, SK Jha†, U Palaria‡, G Joshi#, PK Verma¶, N Pangti§

ABSTRACT Objective: To compare the two techniques of hysterectomy, laparoscopic-assisted vaginal hysterectomy (LAVH) and nondescent vaginal hysterectomy (NDVH), in a retrospective nonrandomized analysis. Material and methods: Eighteen patients in the LAVH group were compared with 22 patients in the NDVH group by the same surgeon, after identifying them from operation theater records and computerized medical records over a period of 15 months. The two groups were compared with respect to intraoperative and postoperative parameters. Results: The mean age, parity, size of uterus and indications of surgery were similar in both the groups. However, LAVH was more expensive and more time consuming compared to NDVH. Otherwise, there was no significant difference between adverse events, recovery time and hospital stay in the two groups. Conclusion: Except for longer operating time and higher cost of surgery in the LAVH group, there was no difference between the two techniques.

Key words: Laparoscopic-assisted vaginal hysterectomy, nondescent vaginal hysterectomy

H

ysterectomy is by far the most frequently performed major surgery in Obstetrics and Gynecology, second only to cesarean section.

Traditionally, it was done by two routes, abdominal or vaginal, but now with the advent of endoscopy a third route i.e., laparoscopic route is gaining popularity.

Though, the vaginal route is the preferred route because of lower morbidity, less operative time and faster recovery, but the Vaginal Abdominal or Laparoscopic Uterine Excision (VALUE) study suggested that 67% of surgeons still use the abdominal approach as the operation of choice, particularly when dealing with pelvic pathology or carrying out oophorectomy.1

Laparoscopic hysterectomy was first done by Reich et al in 1989,2 and since then it has gained widespread acceptance. In laparoscopic-assisted vaginal hysterectomy (LAVH), laparoscopic dissection of parauterine tissues is done to the level of uterine arteries.

It also allows removal of adnexae or adhesiolysis under direct vision more easily than vaginal hysterectomy.

Although, LAVH is becoming increasingly popular, it is more expensive, more time consuming and above all needs special training. On the other hand, vaginal hysterectomy is cheaper, cosmetic (stitchless surgery) and associated with decreased morbidity.3 It can be accomplished even in large sized uterus by bisection, myomectomy, bisection debulking and clampless approach.4 Sheth,5 with his experience of 5,655 vaginal hysterectomies has brought a new dimension to nondescent vaginal hysterectomy (NDVH) in our country.

However, there is ample evidence in favor and against LAVH.6 Summit et al,7 in his randomized trial found the outcomes of NDVH and LAVH similar, but with reduced cost. A surgeon's reluctance to perform vaginal hysterectomy in nonprolapsed enlarged uteri either because of lack of training or experience or fear of increased blood loss because access to uterine arteries sometimes becomes difficult or even impossible especially when dealing with large uterus; may contribute to the preference for LAVH. According to American College of Obstetricians and Gynecologists, 29

CLINICAL STUDY vaginal hysterectomies are preferred in women with a uterus no larger than 12 weeks of gestation size (approximately 280-300 g).8 Recently, the eVALuate study9 concluded that LAVH was associated with a significantly higher rate of major complications than abdominal hysterectomy. LAVH took longer to perform, but was associated with less pain, quicker recovery and better short-term qualityof-life measures.

The aim of the present study was to compare LAVH with NDVH in a retrospective nonrandomized analysis, and to evaluate intraoperative and postoperative complications, operating time, hospital stay and cost of surgery.

Material and Methods This was a retrospective observational study carried out in the Dept. of Obstetrics and Gynecology, Government Medical College, Haldwani (a tertiary teaching hospital) comparing LAVH and NDVH from October 2010 to December 2011.

A total of 40 patients were identified from operation theater records and hospital-based computerized medical records undergoing hysterectomy for nonmalignant conditions by the same surgeon. Eighteen patients in LAVH group were compared with 22 in the NDVH group. The medical records of the patients were reviewed in terms of demographic characteristics, (i.e., age, socioeconomic status and parity, indication for hysterectomy, size of uterus). The intraoperative details like type of anesthesia, necessity of blood transfusion, injury to bladder/bowel or any other complication were studied. Postoperative complications were compared in both the groups.

NDVH was done under spinal anesthesia. Circular incision was made around the cervix. After cutting the pubovesicocervical ligament urinary bladder was pushed upwards. Then anterior and posterior pouches were opened. The uterosacral and Mackenrodt ligaments were clamped, cut and ligated bilaterally. Then the uterine vessels were secured. Next step in bigger sized uteri was uterine bisection, myomectomy or a combination. In case of fundal fibroids myomectomy was done only if the fibroid was interfering with the delivery of fundus. In total hysterectomy last clamp was placed on fundal structures (i.e., round ligament, 30

medial part of fallopian tube, ovarian ligament). In case of salpingo-oophorectomy, after clamping the fundal structures, the ovary was pulled and the clamp was placed on infundibulopelvic ligament. After removing the uterus the vault was closed.

LAVH was done under general anesthesia. Bipolar cautery was used. The uterus was manipulated with the help of myoma screw. The round ligaments were cauterized and cut bilaterally. If adnexa had to be preserved,fallopian tubes and ovarian ligaments were cauterized and cut and in patients requiring salpingooophorectomy, infundibulopelvic ligaments were cauterized and cut. The uterovesical fold of peritoneum was cut. The vaginal procedure began with opening the anterior and posterior pouches. The Mackenrodt's and uterosacral ligaments were clamped, cut and ligated bilaterally. After ligating the uterine arteries, the uterus was brought out and vault closed.

Results The commonest indication for surgery in both the groups was dysfunctional uterine bleeding (DUB), followed by fibroid and cervical dysplasia as shown in Table 1. The age-wise distribution of cases, was almost similar in the two groups. Approximately 55.5% patients in LAVH group and 50% in NDVH group had parity 4-5, a favorable factor for vaginal surgery.

Majority of the patients (72.2% in LAVH group and 63.6% in NDVH group) had uterine size â&#x2030;¤8 weeks. The size was similar in both the groups.

LAVH took significantly longer time than NDVH. The operation could be completed in <90 minutes in 81.8% patients in the NDVH group, while the rest required 90-120 minutes. On the other hand, majority (94.4%) patients of LAVH group required >120 minutes; p valve was 0.001 (Table 2).

One patient of LAVH group had urinary bladder injury and the surgery had to be converted to abdominal hysterectomy, along with urinary bladder repair.

In the NDVH group, one case had to be converted to abdominal hysterectomy because of minimal descent of cervix.

Minor postoperative complications like fever, urinary tract infection were noted in both the groups.

infection on account of ureteric stone. One patient in the NDVH group required readmission, because of secondary hemorrhage, which responded to conservative treatment (vaginal packing, systemic and local antibiotics)(Table 3).

In the NDVH group, majority patients (59.1%) required three suture materials, while in the LAVH group 83.3% required only two suture materials.

One major difference in both the groups was the cost of surgery. Ours being a Government Medical College, the cost of NDVH in our hospital is only ` 800 ± 300, while that of LAVH is ` 4,300 ± 500 (p = 0.001). The cost of medicines used during and after surgery was excluded from this.

Discussion In our study, the mean age of the patients was same for both the groups. The major indication of surgery was DUB in both the groups, and majority of patients had uterine size ≤8 weeks.

Since, the advent of LAVH by Reich in 1989, the uptake of this procedure has been slow and subject to considerable geographic variation. The reasons could be many folds. One is the cost of equipment, as laparoscope is an expensive instrument and may not be available in many hospitals, second is the training for laparoscopic surgery. Laparoscopic surgery needs more training and the learning curve is slow. A third factor is the time, LAVH takes compared to NDVH. This has 31

CLINICAL STUDY been shown in a number of studies,6,10,11 including this one. NDVH took <90 minutes in 81.8% patients, while 94.4% patients of LAVH group required >120 minutes (p = 0.001). Therefore, given the pressure on operating time, there is often a reluctance to spend longer performing a surgery than is required.

A fourth important factor is the cost of surgery. The cost of NDVH was approximately ` 800 ± 300, while that of LAVH is ` 4,300 ± 500. The reasons are two folds, one is the higher cost of laparoscopic surgery and second is the charge of general anesthesia. The charges in our hospital are very low, being a Government Medical College, where the beds are free and majority of medicines are provided free by the government.

However, there was no significant difference in the adverse events, postoperative recovery phase, which were almost similar in both the groups. Like Richardson12 and Roy et al11, we also did not find any difference in terms of blood loss, intra- and postoperative complications, requirement of analgesics, recuperation time and hospital stay.

Conclusion The aim of the present study was to compare NDVH with LAVH. The main findings which came out from this study was the increased operating time and higher cost of surgery in the LAVH group. In comparison NDVH was cheaper and less time consuming.

Otherwise, other outcome variables like intra- and postoperative complications, blood loss, postoperative pain and hospital stay were similar in both the groups.

CASE REPORT

Mullerian Agenesis: An Unusual Presentation as Hematometra and Bilateral Hematosalpinx Sudhir Gupta*, Ankita Kumari†

ABSTRACT A case of hematometra with bicornuate uterus and bilateral hematosalpinx in a 15-year-old girl complicated by vaginal agenesis and absent cervix is presented. She was managed by abdominal hysterectomy and bilateral salpingectomy. Bilateral ovaries were conserved.

Key words: Mullerian agenesis, hematometra, hematosalpinx

M

ullerian agenesis occurs in one out of every 4,000-10,000 females.1 The independent occurrence of congenital hematometra without hematocolpos is a rare mullerian duct anomaly that results from a noncommunicating rudimentary horn with functioning endometrium or primary cervical atresia and absent upper vagina.2-4 Women affected by this disorder often have accompanying renal, skeletal and other anomalies.5

We report a case of bicornuate uterus with hematometra and bilateral hematosalpinx in a 15-year-old girl who presented with acute abdominal pain and 6 × 4 cm pelvi-abdominal mass (Fig. 1).

Case Report A 15-year-old unmarried female presented with complaint of primary amenorrhea with cyclical abdominal pain for past 12 months. Pain was relieved by oral analgesics. There were no bladder or bowel complains. Her general and systemic examinations were within normal limits. Examination per abdomen revealed a firm, well-defined, nontender, noncompressible and nonreducible mass measuring 6 × 4 cm in left iliac fossa. Per rectal examination

was noncontributory. Per vaginal examination was not carried as she was unmarried.

All routine examinations revealed no obvious abnormality. An ultrasound scan of pelvis and abdomen revealed hematometra with bilateral hematosalpinx.

Computed tomography scan showed thick-walled cystic lesion in left lumbar region continuous with hematometra. Examination under anesthesia revealed a blind lower vagina of 2 cm. On rectal examination, tense and firm mass was felt.

A diagnostic laparoscopy was performed that revealed a bicornuate uterus with hematometra; bilateral fallopian tubes were distended and bluish in color suggestive of hematosalpinx. Both ovaries were normal. Stick-like band was seen between lower half of both mullerian ducts.

Figure 1. Intraoperative photograph showing bicornuate uterus with hematometra and bilateral hematosalpinx.

33

CASE REPORT On laparotomy, bilateral hematosalpinx with bilateral normal ovaries and distended bicornuate uterus was found. The lower part of uterus, cervix and upper three-fourth of vagina were not formed. Routine hysterectomy along with removal of both fallopian tubes was done. Both ovaries were conserved. The patient had an uneventful postoperative recovery. Her stitches were removed on the eight postoperative day and she was allowed to go home the same day.

Discussion Complete cervicovaginal agenesis with a functioning endometrium in a bicornuate uterus is an extremely rare mullerian duct malformation.6 Only few cases of such abnormality have been reported along with their surgical procedures.

This 15-year-old girl had cyclical abdominal pain for last 12 months. As she was in perimenarchal age and presented with an abdominal mass, it was suspected to be due to cryptomenorrhea resulting from entrapped menstrual blood in the uterine cavity causing pain.

A pelvi-abdominal ultrasound showed hematometra.

Diagnostic laparoscopy confirmed bicornuate uterus with bilateral hematosalpinx with absent cervix and upper vagina.

Our case emphasizes that mullerian anomalies should be considered among the differential diagnosis of cyclical abdominal pain that responds poorly to analgesics. As developmental anomalies of urinary and mullerian tracts are commonly associated, the former anomalies should be specifically investigated before elective surgery is carried out.

The general consensus of treatment of these patients has been to remove the mullerian structures during initial operation so as to avoid postoperative complications.

The same principle of treatment was applied in the case described.

34

Conclusion When one encounters blocked uterus, it should be thoroughly evaluated especially in adolescents with relevant investigations keeping in mind the rare possibility of mullerian anomaly. Early diagnosis and prompt treatment is recommended in these patients to avoid future gynecological and obstetrical complications. Although technical advances favor reconstructive surgery for cervicovaginal agenesis, it must be emphasized that these complex procedures are not without complications resulting in recurrence of hematometra ultimately requiring hysterectomy.

In this patient, the decision for hysterectomy was considered most appropriate to suit her social circumstances.

Posterior Reversible Encephalopathy Syndrome in Postpartum Normotensive Woman: A Rare Presentation M Siva Sundari*, KS Rajeswari†, Nandhini Elumalai‡

ABSTRACT Posterior reversible encephalopathy syndrome (RES) is a rare acute neurologic condition characterized by headache followed by deterioration, including confusion seizures, or cortical visual disturbances. Our case is a rare presentation of PRES in a postpartum normotensive woman after an uneventful cesarean delivery under spinal anesthesia.

Key words: Posterior reversible encephalopathy syndrome, spinal anesthesia

P

osterior reversible encephalopathy syndrome (PRES) has occurred in patients with hytertensive encephalopathy, renal failure, immunosuppresion and postpartum eclampsia.1,2 We report a case of PRES, which occurred in the postpartum period with normal blood pressure (BP) and managed successfully.

Case Report A 26-year-old primigravida, booked, normotensive was induced at 37 weeks of gestation in view of obstetric cholestasis of pregnancy. She underwent emergency lower-segment cesarean section under spinal anesthesia in view of fetal distress. Postoperatively her BP was normal.

On second postoperative day, patient developed bifrontal headache, particularly when in an erect position, it was relieved by being recumbent. Headache improved (Visual Analog Scale (VAS), 1/10) after supportive therapy including oral analgesics (paracetamol, 2 g/day), intravenous hydration and bed rest. Her BP was 120/70 mmHg. On third postoperative day, patient complained of severe throbbing headache (VAS) 10/10) over the occipital area, which was no longer postural. *Associate Professor † Professor ‡ III Year MS Postgraduate Dept. of Obstetrics and Gynecology Sri Ramachandra University Porur, Chennai, Tamil Nadu Address of correspondence Dr M Siva Sundari L-170, Marvel Apoorva Apartments, 4/12, Kalacsathamman Koil Street Ramapuram, Chennai 600 089, Tamil Nadu E-mail: sivasundaridr@yahoo.com

BP was 130/70 mmHg, treated conservatively with analgesics and intravenous hydration. After 2 hours, she developed blurring of vision followed by one episode of generalized tonic and clonic convulsions.

During postictal period, she had total loss of vision.

Neurologist opinion was obtained. Patient was treated in intensive care unit with magnesium sulfate (Zuspan’s regime) for 24 hours, injection levetiracetam 1 g intravenous b.i.d. for 48 hours and injection mannitol 100 mL infusion t.d.s. for 24 hours. Magnetic resonance imaging (MRI) brain FLAIR T 2-weighted axial image showed bilateral symmetric hyperintense areas involving the bilateral frontal, parietal subcortical white matter, bilateral basal ganglia, occipital and cerebellar hemispheres suggestive of PRES (Figs. 1 and 2). MR venogram was normal, fundus also normal. Throughout her BP was 130/70 mmHg. There was no proteinuria, renal function test, liver function test, serum electrolytes and serum calcium were normal. She completely regained her vision after 24 hours. Her neurological symptoms completely resolved by 48 hours. She was discharged on 8th postoperative day with anticonvulsant medications for 1 month. She was followed up for almost 5 months and she is free of neurological symptoms.

Discussion PRES is a rare acute neurologic condition characterized by headache followed by deterioration, including confusion, seizures or cortical visual disturbances.

PRES has been reported to be reversible.1 PRES refers to a clinicoradiological entity with characteristic features on neuroimaging and nonspecific symptoms comprising headache, confusion, visual disturbances and seizures.3 The lesions in PRES are thought to be

due to vasogenic edema, predominantly in the posterior cerebral hemispheres and reversible with appropriate management.3 The typical MRI findings of PRES are most apparent as hyperintensity of FLAIR images in the parieto-occipital and posterior-frontal cortical and subcortical white matters. Less commonly brainstem, basal ganglia and cerebellum are involved.3 However, irreversible brain damage can sometimes occur due to late-recognition or incorrect treatment.4,5 Importantly, treating the underlying problem usually leads to symptom resolution without neurological deficit.

Acute treatment for cerebral vasospasm is essential.6 Nimodipine, a calcium antagonist has been shown to be associated with a reduced rate of infarction because of cerebral vasospasm, but the efficacy of magnesium, a drug with calcium antagonist properties in treating cerebral vasospasm is comparable to that of nimodipine.6 Several clinical studies have shown that intravascular magnesium sulfate safely relieved maternal cerebral vasospasm.7-9

CASE REPORT

Multiple Fibroids in a Case of MRKH Syndrome with Absent Uterus: Recommendations for Management Shalini Mahana Valecha*, Prajakta Katdare†, Uday Kargar†, Prajakta Shende‡

ABSTRACT Mayer-Rokitansky-Küster-Hauser (MRKH) syndrome is a rare congenital anomaly characterized by aplasia or hypoplasia of uterus and vagina in women with normal development of secondary sex characteristics. It affects one in 4,000-5,000 female births. Women with this syndrome present in their teens with primary amenorrhea. MRKH syndrome may be associated with renal, skeletal, cardiac and auditory anomalies. Although, very rare women with MRKH syndrome may develop leiomyomas from a rudimentary uterus. Initial investigation in women having MRKH syndrome with leiomyoma is ultrasonography (USG). However, magnetic resonance imaging (MRI) is more accurate for diagnosis. Complete removal of the masses with the uterine remnant is recommended.

ayer-Rokitansky-Küster-Hauser (MRKH) syndrome or mullerian agenesis syndrome is a rare congenital anomaly characterized by aplasia or hypoplasia of uterus and vagina in women with normal development of secondary sex characteristics and normal 46 XX karyotype.1 It affects one in 4,500 female births.2 Women with this syndrome present with primary amenorrhea early in life.

Association of pelvic mass with mullerian agenesis can pose a diagnostic dilemma. The uterine remnant, even though rudimentary and either absent or grossly underdeveloped, retains its potential to form tumors.

Notably, if MRKH is rare, masses in this scenario are a rarest of rare association.3 Since adnexa are normal, masses originating from them are other possibilities.4 The initial investigation is usually ultrasonography (USG), although computed tomography (CT) and magnetic resonance imaging (MRI) are more accurate in diagnosis.

Case Report Mrs XYZ, 35 years, presented with complaints of abdominal distension, urinary urgency, ‘big ball moving around in stomach’ and pain in the lower abdomen for 6 months. Patient had never menstruated. Interestingly, she was married and enjoyed an active sex life.

She was of average height and weight with welldeveloped secondary sex characters. A freely mobile, irregular, firm, nontender mass, roughly 6 × 6 cm in size lying on the left psoas muscle was palpated. Such was its mobility that on subsequent examination it had disappeared in the pouch of douglas. External genitalia were normal with a blind vaginal pouch of 4 cm length and absent cervix. On bimanual examination, a hypermobile, firm, globular mass approximately 6 × 6 cm was felt lying in the midpelvis, with two smaller masses of few centimeters on other side. Uterus was not felt as a separate structure.

Rectal examination confirmed absence of uterus.

Except for raised follicle-stimulating hormone (34.64 mIU/mL), hormone profile was unremarkable.

USG abdomen/pelvis showed a hypoplastic uterus with multiple subserosal pedunculated fibroids, largest 6 × 5 cm. Both ovaries were normal. Of note was the fact that urogenital system was normal.

MRI revealed absent uterus, atretic structure in the region of cervix and the upper part of vagina. Lower vagina ended in a blind pouch. Multiple hypointense 37

CASE REPORT masses were seen of 7 Ă&#x2014; 7 cm at the site of the missing uterus. Also there was a soft tissue mass in right adnexa with preserved zonal anatomy of uterus suggestive of right uterine remnant. Both ovaries were unremarkable and there were no renal anomalies (Fig. 1).

On the basis of USG and MRI findings, a provisional diagnosis of multiple leiomyomas with MRKH syndrome was made. Chromosomal study of the patient revealed a normal karyotype of 46 XX. Laparotomy revealed a mere band, where the uterus should have been. A large fibroid of 6 Ă&#x2014; 6 cm was seen arising from the left horn. Also the right horn showed multiple fibroids. Left ovary showed a hemorrhagic cyst and the right ovary was normal (Fig. 2). All the myomas, uterine remnant and left-side tube and ovary

Discussion MRKH syndrome is a rare disorder described as aplasia or hypoplasia of uterus and upper two-third of vagina due to early arrest in development of mullerian duct. Women with this syndrome have normal 46 XX karyotype, normal female secondary sex characters, normal ovarian functions and underdeveloped vagina.1 In addition, women with MRKH syndrome may have renal, skeletal, hearing and cardiac anomalies.

The incidence of MRKH syndrome has been estimated as one in 4,500 female births.2 Leiomyomas in the rudimentary uteri of MRKH patients are exceedingly rare and only few cases have been reported.3 MRKH syndrome can be of two types depending on the extent of uterine hypoplasia, type 1 being completely absent as was the case in this patient.5,6 Leiomyomas of uterus are estrogen-dependent tumors.

Although, mullerian ducts are primarily endodermal in origin, some smooth muscle cells exist at their proximal ends. These may be where leiomyomas arise from.

However, the exact etiopathogenesis of leiomyoma from the rudimentary uterus in MRKH syndrome is not known.

The usual symptoms are primary amenorrhea, infertility and pain, accompanied by large mobile masses that, most of the times, are ovarian in origin. Uterine masses are unexpected and rarely thought of USG followed by MRI helps to delineate the masses as well as evaluate the urogenital system.

were removed. The normal right adnexa was retained considering her young age. She recovered uneventfully.

Uterine horns on cut section were noncommunicating.

Endometrial lining was compressed. The leiomyomas did not show features of degeneration. Histology revealed typical features of leiomyoma with hypoplastic uterus. Sections from left ovary showed hemorrhagic corpus luteal cyst. Left fallopian tube was normal and cervix could not be identified.

MRI allows an accurate evaluation of the uterine aplasia, as well as a clear visualization of the rudimentary horns and ovaries.7 MRI has nearly 100% accuracy in diagnosis of mullerian duct anomalies because of its excellent soft tissue resolution.8 Diagnostic laparoscopy is the gold standard for definitive diagnosis of MRKH syndrome.9 Differential diagnosis of leiomyoma of rudimentary uterus in MRKH syndrome includes Asian Journal of Obs and Gynae Practice, Vol. 1, January-March 2014

CASE REPORT ovarian fibroma, gastrointestinal stromal tumor of intestine and extravesical leiomyoma of urinary bladder.10 Management Extreme anxiety and psychological distress accompany this rare condition making counseling advisable.11 Treatment for patients of MRKH syndrome with leiomyomas is removal of the fibroids with removal of adjacent uterine remnant.12 While no reports of leiomyosarcoma in fibroid associated with MRKH have been reported in the literature, it can well be construed that like other myomas these can also turn malignant, further making removal of the fibroid associated with absent uterus imperative.

Conclusion In summary, we recommend the following guidelines for management of MRKH patients: zz Any associated masses should be thoroughly evaluated keeping fibroid as a remote but possible differential. zz MRI is an investigation of choice. zz Complete removal of all masses is recommended.

CASE REPORT

Torsion of the Postmenopausal Uterus: A Surgical Emergency Anupama Hari*, Adithya H†, Swetha G‡, JiJiya A¶

ABSTRACT Torsion of the nongravid uterus is rare, but can present as an acute abdominal emergency. As it causes irreversible ischemic damage to uterus and its adnexae, emergency laparotomy is mandatory as a diagnostic and therapeutic procedure. We report a case of torsion of fibroid uterus in a postmenopausal woman who presented with an acute abdomen requiring laparotomy.

Key words: Torsion of uterus, uterine fibroids

T

he clinical presentations as an acute abdomen in patients with uterine fibroids may include red degeneration, torsion of the subserous fibroid, torsion of the uterus along with fibroid and sarcomatous degeneration.1 As uterine torsion leads to irreversible ischemic damage to uterus and its appendages, prompt diagnosis and treatment are needed.

In the present case, the patient presented with severe abdominal pain due to torsion of fibroid uterus along with its adnexae. Accurate diagnosis and subsequent emergency management saved the woman from this potentially fatal complication.

Case Report

Computerized tomography (CT) scan of abdomen and pelvis showed a large pelvic mass of 15.7 × 12.8 cm size, which was continuous with the uterus with multiple intralesional areas of degeneration and a preoperative diagnosis of fibroid uterus was made.

Doppler ultrasound revealed hypervascularity of the mass.

Investigations

CA 125: 27 µg/dL

A 52-year-old tribal woman was admitted to our hospital on 26/10/2010, with severe pain abdomen for 2 days. She had two living children and the last childbirth was 22 years ago. Both were normal vaginal deliveries. She reached menopause 3 years ago. On probing, she volunteered that there was mild abdominal heaviness of nearly 2-month duration before coming to the hospital.

T3: 1.29 ng/mL

On examination, her general condition was stable; pulse was 90/minute, blood pressure (BP) was 130/80 mmHg. Abdomen examination revealed 18 weeks

size midline tender mass. The same mass was felt on bimanual examination and cervical movements were also tender. Ectocervix and vagina were found to be normal on speculum examination. Clinically, torsion of an ovarian mass was diagnosed.

T4: 9.4 µg/mL TSH: 2.16 µIU/mL Hb: 9.8 g/dL Clotting time: 3’30” Bleeding Time: 2’18” Blood group: AB+ve Blood urea: 26 mg/dL Serum creatinine: 0.9 mg/dL ECG: within normal limits On 27/10/2010, laparotomy was done using subumbilical midline incision. Multiple fundal subserous fibroids with cumulative measurement of 22 × 15 cm along with several seedling fibroids were found. Uterine torsion of 360° along with its adnexae Asian Journal of Obs and Gynae Practice, Vol. 1, January-March 2014

CASE REPORT was found at the level of isthmus (Fig. 1); both fallopian tubes and ovaries were highly congested and gangrenous. Posterior surface of the fibroids showed arborizing dilated vessels (Fig. 2).

In view of the gangrenous appendages, total abdominal hysterectomy along with fibroids and bilateral salpingo-oophorectomy was performed. Total weight of the specimen was 1.5 kg. Her postoperative period was uneventful. Patient was started on broad-spectrum antibiotics. One unit of blood was transfused during the postoperative period. The case was discharged on 10th postoperative day in a stable condition.

Histopathology of specimen revealed subserous myoma with areas of hemorrhagic necrosis and congestion of uterine body and its adnexae (Fig. 3).

Figure 1. Torsion of 360° of uterus and its adnexae with multiple fundal fibroids.

Discussion Uterine torsion is defined as rotation of uterus in its long-axis by >45°.2 Uterine torsion during pregnancy has been reported in more than 100 cases, but torsion of nongravid uterus is very rare.3 Very few cases of torsion of uterus in postmenopausal women have been reported till date.4 The torsion of uterus is usually at the level of supravaginal cervix, so that uterine vessels are obstructed leading to gangrenous uterus.3,5 Nongravid uterus undergoes torsion only when the uterus is asymmetrical because of tumor or abnormal mullerian duct fusion.5 As uterine torsion causes vascular damage to uterus leading to rapid clinical deterioration, prompt diagnosis and urgent management are needed.6 In the present case, the woman ignored the symptoms, which had been present since 2 months, ultimately resulting in an emergency laparotomy.

Uterine torsion should be considered as a differential diagnosis in all ‘acute abdomen’ cases. The other causes of acute abdomen in fibroid uterus, apart from torsion of fibroid, are uncommon. Red degeneration and sarcomatous degeneration, though rare, should also be considered.1 Very rarely, torsion of fibroids may lead to hemoperitoneum as a result of rupture of veins over the fibroid.1 Cases of torsion of a puerperal uterus with fibroids have also been reported.6 Myomatous uterine torsion is difficult to diagnose preoperatively.7 The clinical spectrum ranges from pain abdomen to distension to shock.7 The differential Asian Journal of Obs and Gynae Practice, Vol. 1, January-March 2014

CASE REPORT diagnosis in a postmenopausal woman should include appendicitis, torsion of a pelvic tumor and bowel obstruction.

Management of torsion of fibroid uterus includes prompt diagnosis and immediate laparotomy to save the life. In most of the cases, the surgery involves removal of diseased uterus along with its appendages.

But, in young women who desire to retain fertility, myomectomy should be considered after assessing the viability of uterus along with detorsion of the uterus.4 The round ligaments and uterosacral ligaments should be plicated to prevent recurrence of torsion if the uterus is to be conserved.4 In our case, the probable cause of uterine torsion by 360° could be the weight of the subserous fibroids acting on weak musculature of the postmenopausal uterus. Hence, the entire uterus along with fibroids was congested, necrosed and gangrenous. A total hysterectomy with bilateral salpingo-oophorectomy was performed.

Whenever large subserous fibroids are diagnosed, they should be surgically treated even though they are asymptomatic as they are prone to life-threatening complications like torsion of the uterus, avulsion of the fibroid and hemoperitoneum.8

CASE REPORT

Unilateral Atresia of Cervix Uteri and Uterus Didelphys in a Girl with Operated Congenital Pouch Colon Sangeeta Gupta*, Taru Gupta†, Akshay Sharma‡, Pushpa Bhatia¶, Nupur Gupta§

ABSTRACT This case report describes a girl with uterus didelphys with unilateral hematometra and hematosalpinx with congenital pouch colon (CPC) condition, where all or part of the colon is replaced by a pouch-like dilatation (5-15 cm in diameter), which communicates distally with the urogenital tract through a large fistula and associated with anorectal agenesis (supralevator anorectal malformation). CPC is seen in Asia and more specifically in northern India, Pakistan and Nepal. The management summary of this condition is creation of diverting colostomy at birth with or without the excision of pouch followed by pull through (abdominoposterior saggital anorectoplasty) later on. The girl underwent similar procedure at birth and subsequent definitive surgery (pull through), to create a neoanus at 15 months of age. Subsequently since menarche, the child had severe cyclical abdominal pain, which on investigation was found due to hematometra and hematosalpinx in right-sided uterus.

Laparotomy with removal of right-sided uterus and right fallopian tube was performed. Right-sided uterus had atresia of cervix uteri. This report emphasizes the need for comprehensive evaluation and a long-term management strategy for associated gynecologic anomalies in girls with CPC, especially with regard to patency of the outflow tract.

Key words: Anorectal malformation, congenital pouch colon, cervical atresia, hematometra, uterus didelphys

U

terus didelphys with unilateral cervical atresia is an unusual mullerian duct anomaly with defect of vertical-lateral fusion. A well-known clinical association of congenital pauch colon (CPC) with genital anomalies exists.1 At puberty, they present with incapacitating dysmenorrhea shortly after menarche. Similar findings in a girl with CPC have not been reported earlier in the literature.

emergency laparotomy with ileostomy was done at age of 15 days, followed by pull through to create a neoanus operation at age of 18 months and intraoperative findings suggested a type III CPC. Closure of colostomy was done at 2 years of age. Menarche was attained at the age of 10 years and she started having cyclical pain lower abdomen, unrelieved with medications. She was subsequently imaged in the private sector.

Case Report

Ultrasound (whole abdominal and pelvis) showed both kidneys, uterus as normal and cystic mass in midline and towards right, 7.7 × 4.3 cm with internal echoes with a volume of 75 cc. Left ovary was normal.

Contrast-enhanced computed tomography (CECT) abdomen showed a normal uterus with tubo-ovarian mass in right adnexa probably of infective etiology. CT urography and micturating cystourethrogram showed normal urethra and urinary bladder.

A 10.5-year-old girl attended gynecology OPD with complaint of severe colicky abdominal pain since attainment of menarche. Pain was cyclical in nature occurring at monthly intervals. Periods were regular.

There was history of multiple surgeries for associated CPC. On examination, there were three scars on abdomen. Available old records of child revealed that she was a diagnosed case of CPC, for which an

Local examination showed normal perineum with patulous vagina and normally placed neoanus with visible rim of anal mucosa.

Magnetic resonance imaging (MRI) at our institute showed uterus didelphys with obstructing hemivaginal septum with right hematometra and hematosalpinx.

Left uterine cervix was identified while cervix could not be identified in right uterus. Right ovary was not visualized separately. Clinical diagnosis of mullerian 43

CASE REPORT duct anomaly, Class IV American Fertility Society (AFS) classification of uterovaginal anomalies, unusual configuration of vertical-lateral fusion was made.

Lateral fusion defect of mullerian ducts may be the cause of uterus didelphys and vertical fusion disorder might have resulted in right cervical agenesis.

Examination under anesthesia showed a normal urethral orifice, patulous vagina and normally placed patulous neoanus. Perspeculum examination showed normal vagina except a partial vaginal septum in the upper third of vagina. Normal well-developed cervix was present on left side. Menstrual blood was coming through the os. Per vaginum examination showed small-sized uterus in continuation with cervix on left side. On right side, no cervix could be felt, firm mass of 5 Ă&#x2014; 4 cm was felt. Uterine sound was put through left cervical os into uterine cavity. Left uterocervical length was 6 cm.

Laparotomy was done, which revealed uterus didelphys with right uterus distended with blood and a large right hematosalpinx. Right-sided ovary could not be visualized. Left-sided uterus, fallopian tube and ovary were normal. Removal of right-sided uterus and right hematosalpinx was done. There was complete cervical atresia on right side. The postoperative period was uneventful.

The histopathological examination confirmed right-sided hematosalpinx and right-sided uterus with no cervix.

Discussion Mullerian ducts represent the primordial components of the female reproductive system. They differentiate into fallopian tubes, uterus, cervix and superior aspect of vagina. Overall published data suggest prevalence of uterovaginal anomalies of 1-6%.2 Complete failure of medial fusion of two mullerian ducts can result in complete duplication, partial failure of fusion can result in a single vagina with a single or duplicate cervix and complete or partial duplication of the uterine corpus.

If uterine anomaly is associated with obstruction of menstrual flow, then it causes symptoms that will come to the attention of the gynecologist shortly after menarche.3 Early diagnosis offers significant advantages in patient care.

Incapacitating dysmenorrhea shortly after menarche with regular menstrual periods in young girls can be due to 44

unicornuate uterus with a noncommunicating rudimentary anlagen containing functional endometrium, unilateral obstruction of a cavity of a double uterus (complete septum), a clinical syndrome consisting of a double uterus, obstruction of vagina and ipsilateral renal agenesis or unusual configuration of vertical-lateral fusion defects Class IV AFS, as in our case where there was uterus didelphys with unilateral cervical atresia.

It is important to make diagnosis as soon as possible, because if lumen of tube communicates with functional endometrial cavity and is patent at fimbrial end, then retrograde menstruation and pelvic endometriosis can develop, destroying reproductive potential. Removal of associated fallopian tube is strongly recommended to minimize risk of an ectopic pregnancy.3 Asian Journal of Obs and Gynae Practice, Vol. 1, January-March 2014

CASE REPORT There are very few reports of uterus didelphys, a finding that appears to be invariable in girls with types I-III CPC.4 Chadha et al described a girl with CPC, uterus didelphys with bilateral cervical atresia. At puberty, child had primary amenorrhea with severe cyclic abdominal pain due to hematometra, hematosalpinx and endometriosis. Laparotomy with removal of both uteri was done. Both uteri had atresia of cervix uteri.5 In a recent review on the subject of gynecologic concerns in girls with anorectal malformation (ARM), Breech6 emphasized the role of vaginoscopy before puberty, preferably at the time of definitive repair of the ARM. Vaginoscopy allows evaluation of the vaginal anatomy and can also document the appearance, development and position of the cervices in vagina and the presence or absence of mucus at the ectocervix (to infer patency).

Any underdevelopment of the Müllerian structures can be detected by serial US starting soon after the onset of breast development.6 If neglected, onset of menarche in the presence of obstruction to the outflow tract may result in hematometra and/or hematocolpos, hematosalpinx, adnexal cysts, endometriosis and chronic abdominal pain.

Conclusion In conclusion, our report emphasizes the need for a comprehensive evaluation and long-term management strategy for associated gynecologic anomalies in girls with CPC, especially with regard to the patency of the outflow tract. Uterus didelphys with a septate vagina appears to be invariable in girls with types I-III CPC4 and needs to be assessed and managed appropriately with awareness of the possibility of

obstetric complications in later life.7,8 Therefore, it is strongly recommended that these parents of such patients are duly counseled and the entire case record with operative findings are to be preserved. It is also advocated that treating pediatric surgeon should team up with gynecologist for ideal long-term management.
