In this article, we describe important tips and tricks in EP of ampullary tumors on the basis of our large case series outcome. Between May 1999 and April 2014, 115 patients underwent EP at Tokyo Medical University hospital. The mean tumor diameter was 16.2 (6\u201335) mm. The final pathological diagnoses were adenoma, cancer in adenoma, cancer, and hyperplasia in 85, 13, 10, and seven patients, respectively. \u201cEn bloc\u201d or \u201cpiecemeal\u201d EP was performed with a polypectomy snare forceps using \u201cEndocut\u00ae mode\u201d. Prophylactic pancreatic duct stents were placed after EP. Consequently, a single treatment session was possible in 93 (80.9%) patients. Additional treatment was required in the remaining 22 (19.1%) patients. For these 22 patients, the postresection pathological diagnoses were adenoma in 15 patients and cancer in seven patients. Two patients with cancer and venous permeation required surgical operation. The final complete resection rate was 98.2%. Several complications observed included pancreatitis (10.4%), bleeding (18.2%), perforation (2.6%), cholangitis (1.7%), and papillary stenosis (4.3%). One patient died of procedure\u2010related complications. In conclusion, endoscopic papillectomy showed a high technical success rate. However, possible complications and occasional fatal complications should be considered when using
