title: Pancreaticobiliary fistula associated with pancreatolithiasis.
abstract: We report here a case of pancreaticobiliary fistula associated with pancreatolithiasis. A 47-year-old female without a habit of alcohol drinking was admitted by her family physician after suffering from mild acute pancreatitis. Computed tomography revealed mild acute pancreatitis with pancreatolithiasis at the head of the pancreas. The pancreatolithiasis was exposed to the inner surface of the common bile duct and possibly compressed and narrowed the Wirsung and Santorini ducts, resulting in the pancreatitis attack. We used extracorporeal shock wave lithotripsy to treat the pancreatolithiasis. After complete elimination of stones by extracorporeal shock wave lithotripsy, endoscopic retrograde cholangiography showed an apparent pancreaticobiliary fistula between a branch of the Santorini duct and the lower portion of the common bile duct. There was no communication between the bile duct and the Wirsung duct or its branches; therefore, the diagnosis was not pancreaticobiliary maljunction. There have only been a few reports of pancreaticobiliary fistula without an association with pancreatic pseudocysts or intraductal papillary-mucinous pancreatic neoplasm, and there have only been few reports of pancreaticobiliary fistula with pancreatolithiasis.
