A B DOMI N AL WALL H E RN I A Abdominal wall hernias are among the most common problems that may require a surgical solution. An estimated 10 percent of the population may suffer from a hernia in their lifetime, and the FDA reports that more than 1 million people in the United States have hernia repairs each year. A hernia is a protrusion of part of an internal organ from the cavity where it normally resides through a preexisting or acquired defect in the wall. Most common abdominal wall hernias are external and may be visible as a permanent or periodic bump in groins (inguinal and femoral hernia), around the navel (umbilical hernia) and along the middle line of the belly (ventricular hernia). Internal abdominal hernias are protrusions of abdominal organs into another internal space. The most known is a hiatal hernia, which is a protrusion of the stomach (gaster) through the diaphragm into a chest cavity. The most common abdominal wall hernia is an inguinal hernia, which is a protrusion of the intestines through the abdominal wall in the groins and sometimes into the scrotum. Inguinal hernias may be indirect and occur due to an incomplete closure of a passage through which the testicles descend from the abdomen into the scrotum. The condition usually occurs early
