Bouveret Syndrome: A Rare and Dangerous Cause of Gastric Outlet Obstruction.

Bouveret syndrome is a rare and dangerous complication of cholelithiasis in which a gallstone lodges in the distal stomach or proximal duodenum, resulting in gastric outlet obstruction. We report the case of an 85-year-old female that presented without many of the clinical symptoms and complaints characteristic of gallstone ileus, further complicated by significant cardiac pathology. We review the existing studies of this uncommon disease and discuss its clinical presentation, diagnosis, and therapeutic options.
