Gastric outlet obstruction by a gallstone (Bouveret's syndrome).

Gastric outlet obstruction caused by a gallstone in the duodenum or pylorus(Bouveret's syndrome) is a very rare complication of gallstone disease. Presenting symptoms include epigastric pain, nausea, and vomiting. Preoperative diagnosis is not easy. Oral endoscopy is one of the diagnostic procedures. We present a case in which the diagnosis was made by endoscopic examination. Multiple attempts at endoscopic extraction of the gallstone from the duodenum were unsuccessful. A one-stage surgical procedure consisting of the removal of the impacted stone, fistula repair, and cholecystectomy was performed in this case. The postoperative course was uneventful.
