We encountered a 65-year-old man with a carcinoid tumor of the minor duodenal papilla. Since he had liver cirrhosis and completely refused surgery, we performed an endoscopic snare papillectomy. The papillectomy was performed successfully without procedure-related complication. The specimens revealed a carcinoid tumor showing that the margin of the tumor was positive. One week later, upper GI endoscopy was performed and the biopsy specimens obtained from base of ulcer showed no neoplastic cells. We performed a duodenoscopy and CT 3, 6 and 18 mo later, and there was no macroscopic or microscopic evidence of tumor recurrence after more than 4 years.
