title: Duodenal obstruction by gallstone: case report of Bouveret's syndrome.
abstract: Bouveret's syndrome involves gastric outlet obstruction by gallstone. Herein we describe an unusual case of duodenal bulb obstruction by gallstone. An 80-year-old woman was hospitalized with a fifteen-day history of vomiting. Computed tomography (CT) showed pneumobilia and a round calcified mass in the second portion of the duodenum. Upper gastrointestinal tract series demonstrated the same sized oval radiolucency between the bulbus and the second portion of the duodenum. Endoscopic examination revealed a round black mass in the second portion of the duodenum, totally occupying the lumen. Endoscopic removal and destruction of the gallstone was attempted using a dye-laser, but the stone was too hard to crush. Eventually surgical enterolithotomy was successfully performed without cholecystectomy or closure of the fistula. Improved preoperative systemic management and prompt examination allowed earlier surgical intervention and reduced the morbidity. Surgical approach whether fistula closure should be performed remains controversial.
