On this basis, we have employed a novel modified endoscopic papillectomy (ESP). In this study, we evaluated the feasibility and advantages of this ESP for the treatment of duodenal major papilla adenoma.<\/jats:p>\n<\/jats:sec><jats:sec>\n<jats:title>Methods<\/jats:title>\n<jats:p>A total of 56 patients with duodenal major papilla adenoma confirmed by endoscopic ultrasonography, intraluminal ultrasound and gastroscopic biopsy from October 2007 to June 2017 were collected in the Department of Gastroenterology, Nanjing Drum Tower Hospital. The diameter of the adenoma ranged from 1.41 to 2.02\u00a0cm. 16 cases were given the conventional method and 40 cases underwent the modified ESP procedure in which a small incision was made by cutting current when anchoring the snare tip on the distal side of the adenoma.<\/jats:p>\n<\/jats:sec><jats:sec>\n<jats:title>Results<\/jats:title>\n<jats:p>En bloc resection rate was significantly higher in the modified group (100%, 40\/40) than that in the conventional group (81.3%, 13\/16; <jats:italic>P<\/jats:italic>\u2009=\u20090.02).

There was no significant difference in the number and difficulty of postoperative pancreatic and biliary stents placement between the two groups (<jats:italic>P<\/jats:italic>\u2009=\u20090.20).
