Duodenal obstruction by a gallstone (Bouveret's syndrome) managed by endoscopic stone extraction: A case report and review

Abstract

Gastric outlet obstruction caused by a large gallstone in the duodenum or pylorus (Bouveret's syndrome) is rare complication of gallstone disease. The presenting symptoms are often nonspecific and include nausea, vomiting, epigastric pain and a history of gallbladder disease. Although the diagnosis is established only at surgery in many cases, preoperative recognition by imaging techniques and endoscopy is desirable. Surgical treatment aims at removal of the ectopic gallstone, closure of the fistula and cholecystectomy. A case of Bouveret's syndrome is presented where endoscopic extraction of the duodenal gallstone was accomplished providing definitive treatment for this patient.
