We report a 15-year boy who presented with obstructive cholangiopathy and pancreatitis after blunt abdominal trauma. A magnetic resonance cholangiopancreatography showed dilated common bile duct, dilated hepatic ducts, and a suspicious choledochoduodenal fistula. An endoscopic retrograde cholangiopancreatography revealed a parapapillary choledochoduodenal fistula. An operation of choledochojejunostomy, excision of common bile duct, and cholecystectomy was done for recurrent cholangitis. Abdominal symptoms completely subsided one month later.
