Abstract

We report the case of a 46-year-old woman who presented with chronic intermittent abdominal pain without jaundice; abdominal ultrasonography showed thickening of the gallbladder wall and dilatation of the bile duct. Endoscopic retrograde cholangiopancreaticography showed pancreatobiliary maljunction with proximal common bile duct dilatation. Pancreatobiliary maljunction was diagnosed. A computed tomography scan of the abdomen showed suspected gallbladder cancer and distal common bile duct obstruction. A pancreatic head mass was incidentally found intraoperative. Radical cholecystectomy with pancreatoduodenectomy was performed. The pathological report showed gallbladder cancer that was synchronous with pancreatic head cancer. In the pancreatobiliary maljunction with pancreatobiliary reflux condition, double primary cancer of the pancreatobiliary system should be awared.

Core tip: We reported a case of 46-year-old women presented with chronic intermittent abdominal pain without jaundice. Endoscopic retrograde cholangiopancreaticography revealed pancreatobiliary maljunction. Radical cholecystectomy with pancreatoduodenectomy was performed. Pathological report showed gallbladder cancer synchronous with pancreatic head cancer. In the pancreatobiliary maljunction with pancreatobiliary reflux condition double primary cancer of pancreatobiliary system should be kept in mind.
