Sixteen patients underwent the modified technique, which consists of resection with the Endocut<jats:sup>\u00ae<\/jats:sup> mode, followed by biliary\/pancreatic sphincterotomy and stenting (Group A). Twelve patients who had undergone EP, using a cutting current, followed by pancreatic duct stenting were included as control (Group B). The frequency of complications and clinical outcomes were retrospectively compared between the two groups.<\/jats:p><jats:p><jats:bold>Results:\u2002<\/jats:bold> Sixteen patients had adenoma, and 12 had adenocarcinoma. Early complications occurred in 36% of all patients (hemorrhage, 7; cholangitis, 3; perforation, 2; cholecystitis, 1). The frequency of early complications in Group A was significantly lower than that in Group B (6% <jats:italic>vs<\/jats:italic> 75%, odds ratio [OR] 0.022, 95% confidence interval [CI], 0.0020\u20130.25). Late complications occurred in 18% of the patients (bile duct stone, 3; hemorrhage, 1; pancreatitis, 1). There was no significant difference in the late complication rate between Group A and Group B (19% <jats:italic>vs<\/jats:italic> 17%). Local recurrences were found in 14% of the patients, without a significant difference between Group A and Group B (19% <jats:italic>vs<\/jats:italic> 8%) during a mean follow\u2010up period. All recurrent tumors were successfully treated with argon plasma coagulation.<\/jats:p><jats:p><jats:bold>Conclusions:\u2002<\/jats:bold> The modified technique of EP for ampullary neoplasm contributed to lessening the occurrence of early complications. However, further refinement of this technique is necessary for improving the clinical outcome.<\/jats:p>","DOI":"10.1111\/j.1443-1661.2011.01161.x","type":"journal-article","created":{"date-parts":[[2011,6,3]],"date-time":"2011-06-03T08:36:40Z","timestamp":1307090200000},"page":"30-35","source":"Crossref","is-referenced-by-count":48,"title":["IMPACT OF TECHNICAL MODIFICATION OF ENDOSCOPIC PAPILLECTOMY FOR AMPULLARY NEOPLASM ON THE OCCURRENCE OF COMPLICATIONS"],"prefix":"10.1111","volume":"24","author":[{"given":"KEI","family":"ITO","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"NAOTAKA","family":"FUJITA","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"YUTAKA","family":"NODA","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"GO","family":"KOBAYASHI","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"TAKASHI","family":"OBANA","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"JUN","family":"HORAGUCHI","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"SHINSUKE","family":"KOSHITA","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"YOSHIHIDE","family":"KANNO","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"TAKAHISA","family":"OGAWA","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"YUSUKE","family":"KATO","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"YASUNOBU","family":"YAMASHITA","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2011,6]]},"reference":[{"key":"e_1_2_6_2_2","first-page":"236","article-title":"Two cases with ampullary cancer who underwent endoscopic excision","volume":"23","author":"Suzuki K","year":"1983","journal-title":"Prog.
