Choledochoduodenal fistula: a rare complication of duodenal ulcer. Case report.

In a 29-year-old man with pyloric obstruction, plain abdominal radiography showed gas in the biliary tree. Gastroscopy revealed severe duodenal stenosis with a large posterior ulcer, and barium from a test meal passed into the common bile duct. Ten days after truncal vagotomy and gastrojejunostomy, signs of ascending cholangitis appeared. Following antibiotic treatment and cholecystectomy the patient recovered.
