RESUMEN
A Pancreaticobiliary fistula is a rare complication of acute necrotizing pancreatitis or pancreatic abscess. One case is herein reported of pancreaticobiliary fistula that was found following removal of pancreatic duct stones by extracorporeal shock-wave lithotripsy and endoscopic sphincterotomy. The patient was a 53-year old woman who was admitted with epigastric pain and fever. Endoscopic retrograde pancreatography revealed multiple stones in the main pancreatic duct. Pus from the pancreatic duct was drained through the major papilla during cannulation. On balloon cholangiogram obtained after removal of the stones, a direct fistulous connection between the main pancreatic duct and distal common bile duct was noted. It is speculated that pancreatic abscess or mechanical compression of pancreatic duct stones may contribute to the destruction of the intrapancreatic bile duct, which leads to the formation of a pancreaticobiliary fistula.
