title: Gallstone ileus in the absence of the gallbladder: case report and review of the literature.
abstract: Although small-bowel obstruction due to gallstone ileus is uncommon, it assumes increasing importance with advancing age. The obstructing gallstone enters the bowel through an internal fistula between gallbladder and duodenum. The authors describe the case of a patient who had undergone cholecystectomy and in whom gallstone ileus occurred secondary to a stone that entered the bowel through a choledochoduodenal fistula. Treatment was traditional with removal of the obstructing stone, but the fistula was left undisturbed. The authors believe that further biliary tract symptoms are unlikely. The patient was well 8 weeks after operation and roentgenograms indicated that the internal biliary fistula was patent.
