 We conducted a survey(involving 13 medical facilities)regarding the results of endoscopic resections in a total of 1,397 cases ; papillary tumors of the duodenum were not included in our survey. Perforated cases were 7.0%(75/1,397)of the total ; there were 5.4%(75/1,397)cases of intraoperative perforation and 1.6%(22/1,397)cases of delayed perforation. Postoperative hemorrhage occurred in 3.6%(50/1,397)of cases. With respect to procedure, endoscopic submucosal dissection(ESD)was the most commonly performed procedure(16%)in perforated cases. The proportion of ESD in the total cases decreased from 41% to 27% during these 5 years. Although new procedures such as cold snare polypectomy and underwater endoscopic mucosal resection have commenced during these 5 years, endoscopic treatment for duodenal tumors has not yet been generalized.
