Adenomas of the major duodenal papilla are rare but clinically important since they are a premalignant condition. Endoscopic mucosal resection has emerged as the first line therary for ampullary adenoma. However, various complications such as pancreatitis, bleeding or duodenal perforation have been reported after endoscopic mucosal resection. To our knowledge, cholangitis has not been reported as a complication of the procedure in the literature. We report a case of papillary stenosis and cholangitis caused by endoscopic mucosal resection of ampullary adenoma. We performed the endoscopic biliary spincterotomy followed by biliary stenting and cholangitis was successfully controlled.
