A 85-year-old man underwent cholecystectomy due to gallbladder stone in 1980. He had fever and abdominal pain occasionally for 4months, then visited our out patient department on October, 1993. Laboratory data showed the elevation of CRP and biliary enzymes. After admission, the common bile duct (CBD) stones were recognized by abdominal ultrasonography (US). Endoscopic retrograde cholangiography (ERC) showed the dilatation of the CBD with three stones. There was a fistula in the duodenal bulb in which bile discharge was confirmed at endoscopy. Cholangiography from the fistula showed significant CBD and stones. We made a diagnosis of cystic duct remnant-duodenal fistula which is considered an extremely rare case from review of the literature.
