A 52-year-old man was hospitalized for the complaints of right hypochondralgia and back pain. He had an episode of right hypochondralgia 2 years ago, and a year later he developed jaundice. ERCP was performed and dilatation of the common bile duct was found. However, no other abnormal findings were found and jaundice was improved within 2 months. A year later on admission, ERCP showed a marked dilatation of the common bile duct again, and no stones and tumors. Endoscopic sphincterotomy was performed for the purpose of biopsy. Two weeks later, a small tumor was recognized between the orifice of the common bile duct and that of the pancreatic duct on ERCP. Biopsy diagnosis was well differentiated adenocarcinoma. Pancreaticoduodenectomy was carried out (1984. 7. 30) and the surgical specimen revealed the tumor locating within Oddi's muscle sheath, and infiltrating along with the bile duct and pancreas tissue to a small extent. It is considered that endoscopic sphincterotomy is very useful for dignosis of non-exposed type carcinoma at the papillary portion of the duodenum.
