Abstract

Recently, endoscopic submucosal dissection (ESD) for the duodenal tumors has come to be treated in many institutions, but has also showed many problems of feasibility and safety compared with endoscopic mucosal resection (EMR). Although duodenal ESD is expected to be more effective for the prevention of postoperative local recurrence, high incidence rate of duodenal perforation and emergency surgical rescue are big problem. Prophylactic mucosal closure by clipping device, polyglycolic acid sheets shielding, and the laparoscopic and endoscopic cooperative surgery are reported to be effective measures to overwhelm the various problems associated with duodenal ESD. However, duodenal ESD still has quite a bit of room for improvement of the procedure, and currently the indication should be well discussed before treatment in consideration of the expected therapeutic effect and complications.
