title: Pancreatic choledochal fistula complicating acute pancreatitis.
abstract: BACKGROUND
  Biliary tract involvement in acute necrotizing pancreatitis is rare.
  
  
  METHODS
  We report a case of a 53-year-old man who had a pancreatic choledochal fistula complicating acute necrotizing pancreatitis. The fistula was suspected at computed tomography and confirmed at surgery. The patient underwent necrosectomy, cholecystectomy and proximal biliary diversion. He is well at 1-year follow-up.
  
  
  CONCLUSIONS
  Simultaneous presence of air in the biliary tree and pancreatic collection is highly suggestive of a pancreaticobiliary fistula. Pancreatic necrosectomy and proximal biliary diversion resulted in closure of the fistula.
