Innovative Therapeutic Endoscopy of the Upper Gastrointestinal Tract: Review of the Japan Gastroenterological Endoscopy Society Core Sessions.

The Japanese Gastroenterological Endoscopy Society (JGES) established four core sessions on endoscopic treatment for upper gastrointestinal diseases under the theme 'Innovative Therapeutic Endoscopy' between 2023 and 2024. This review summarizes these sessions and compiles them as a conference report. At the 105th JGES Core Session, 14 studies were presented as frontiers of treatment for upper gastrointestinal stenosis. At the 106th JGES Core Session, 13 research findings were presented as developments of new endoscopic techniques for the management of neoplastic lesions in the upper digestive tract. At the 107th JGES Core Session, reports were presented from 14 institutions concerning innovations in therapeutic endoscopy, including endoscopic treatment advancements for upper gastrointestinal diseases in internal medicine and surgery. At the 108th JGES Core Session, research from 11 institutions was presented on endoscopic treatment for upper gastrointestinal bleeding. These four core sessions enabled us to recognize the current state of treatment and management approaches for neoplastic lesions, strictures, and bleeding in the upper gastrointestinal tract, and to clarify future challenges. We hope this will contribute to the advancement of upper gastrointestinal endoscopic therapy.
