2021 消化系聯合學術演講年會
外賓演講（一） CUTTING-EDGE OF DIGESTIVE ENDOSCOPY IN JAPAN Hisao Tajiri Senior Adviser, Japan Gastroenterological Endoscopy Society (JGES) President, Japan Endoscopy Database (JED) Institute
Japan Gastroenterological Endoscopy Society (JGES) was established as Japan Gastrocamera Society in 1959. In 1973, the title of the society was changed to Japan Gastroenterological Endoscopy Society to focus on the gastroenterological endoscopy. The society had a membership of only 280 at the time of establishment, but it has grown to over 34,623 members in 2020. JGES is dedicated to advancing patient care and welfare, by promoting digestive disease research through endoscopy, developing and advancing endoscopic practice. Our recent activities are as follows; promoting endoscopic researches, educational seminars and lectures, two congresses every year (individual annual congress in spring and JDDW in autumn), regional meetings (meetings held by 10 regional chapters). JGES started Japan Endoscopy Database (JED) Project in 2015. The aim of this project is to construct a “dream” database to benefit both doctors and patients. This will realize an ambitious strategy to create the world’s leading database with approximately 17 million additional data every year when it is fully operational. By JED, we seek to take an initiative in the construction of infrastructure to conduct international joint researches, and we indeed have been promoting several researches of AI-assisted endoscopy with JED. Development of AI by National Institute of Informatics (NII) leads to the applications of endoscopic screening. The project aims to develop “AI” which is highly versatile and has been already utilized by many medical and screening institutes. Current AI technology is realized to decrease the rate of missed lesions during endoscopy and to decide
the accurate endoscopic treatment strategy. In the near future, we hope the following points; reduction of time and misdiagnosis, technical support in therapeutic endoscopy, and homogenization of diagnosis. The challenges we are working on are as follows; 1) While Image-Enhanced Endoscopy (IEE) developed in Japan has spread and contributed to the standardization of diagnosis at the global level, we aim to further improve the quality. For that purpose, we are further enhancing our educational programs not only in Asian countries but also all over the world and further promote internationalization projects. 2) By advancing the spread of endoscopic screening, we construct an efficient screening system to detect and diagnose many early cancers and provide minimally invasive therapy to more patients, and as a result, contribute to medical cost reduction. 3) With respect to endoscopic therapy for GI malignancies, innovation has been issued from Japan to the world nearly every 15 years, with polypectomy, EMR, and ESD. Soon there will be an emergence of new technologies that will transform future endoscopic treatment. The development and spread of safer and more reliable endoscopic treatment is the most important mission. In the future, in order to stay innovation and to lead further, what we have to do is to promote cooperation of GI endoscopists and surgeons, as well as the promotion of research and development in a midto long-term perspective with the cooperation between industry and academia. In addition to the fusion of expert human skills and machinery (robot technology), it is important to evolve the next generation technology combining AI and information systems.
