Cholecystoduodenal fistula.

An elderly woman with a history of cholelithiasis was seen for right upper quadrant pain and jaundice. During her evaluation, she was found to have extensive choledocholithiasis and a cholecystoduodenal fistula. Successful management was accomplished with cholecystectomy, removal of the common bile duct stones, and by creating a choledochoduodenostomy where the fistula had been present.
