Bouveret's Syndrome with Severe Esophagitis and a Purulent Fistula

Extracted text; Bouveret's syndrome is a rare variant of gallstone ileus with an overall incidence of 1–3%. It is a rare cause of gastric outlet obstruction resulting from the passage and impaction of a large gallstone through a cholecysto-duodenal fistula. A combination of diagnostic modalities is often required for a diagnosis. Management options include endoscopy and surgery. The most commonly performed procedures are enterolithotomy or gastrostomy, either alone or with cholecystectomy and fistula repair. We describe a unique variant of chronic Bouveret's syndrome with the unusual associations of severe esophagitis and a purulent fistula
