Abstract
We herein report a case of ampullary cancer in 65-year-old man who underwent endoscopic papillectomy. Duodenoscopy revealed an exposed-type tumor mass at the ampulla of Vater. Histology of the biopsy specimen demonstrated well-differentiated adenocarcinoma. Endos-copic ultrasonography and intraductal ultrasonography showed a hypoechoic mass limited to the ampulla of Vater (clinical stage, T1). Endoscopic papillectomy was performed after informed consent was obtained. Histological examination of the resected specimen revealed adenocarcinoma limited to the ampulla of Vater (final stage, pT1). Both accurate preoperative T staging and proper histological evaluation of the resected specimen appear to justify endos-copic treatment of early ampullary cancer.
