A 65-year-old female complaining of epigastric pain was admitted to our hospital. Laboratory data showed the elevation of biliary and pancreatic enzymes. The swelling and redness of papilla of Vater was observed by duodenoscope. The biopsy examination revealed adenocarcinoma. ERCP showed pancreas divisum, and the ventral pancreatic duct was dialated. EUS and IDUS showed a hypoechoic mass of about 20 mm diameter at the papilla of Vater, and the invasion into the pancreatic duct could not be excluded.
Surgical material revealed papillary adenocarcinoma of 25mm in size showing no invasion into duodenum and pancreas. The surgical stage was stage I. We reviwed 6 cases of pancreas divisum concomitant with carcinoma of papilla of Vater in Japanese literature.
