title: A case of early carcinoma of the papilla of Vater confined to the mucosa and continuative epithelium of glands in Oddi's sphincter (m-God) treated by endoscopic papillectomy.
abstract: We herein report a case of early stage ampullary cancer, treated by endoscopic papillectomy, in which tumor extension was confined to the mucosa and adjacent epithelium of the glands in Oddi's sphincter. A 77-year-old man underwent screening esophagogastroduodenoscopy, which revealed a mass in the papilla of Vater, which was well-differentiated adenocarcinoma as proven by biopsy. The tumor was diagnosed as T1 and endoscopic papillectomy was performed. Histological examination showed adenocarcinoma limited to the mucosa of the common channel and continuative epithelium of the neighboring glands in Oddi's sphincter. No signs of recurrence have been observed during a follow-up of 23 months.
