 We conducted a survey(involving 13 medical facilities)concerning the results of endoscopic resection in a total of 421 cases, but papilla tumors of the duodenum were not included in our survey. Perforated cases were 12%(52/421)of the total, 9.3% were of intraoperative perforation(39/421), 3.1% were of delayed perforation(13/421), respectively. By procedure, intraoperative perforation was 3.9% in EMR(10/254), 24% in ESD(40/167)and delayed perforation was 1.2%and 6% respectively. By region, delayed peforation was 0.8% in the duodenal bulb and 4.1% in the duodenal second and third portion. Hemorrhage occurred in 6.7%(28/421)and emergency surgery was carried out in 2.6%(11/421)of cases. In cases of emergency surgery intraoperative perforation occurred in 18%(7/39)and delayed perforation occurred in 23% as well(3/13). Post operative hemorrhage occurred in 3.6%(1/28).
