Bouveret syndrome: a case report.

Bouveret syndrome is characterized by the migration of a gallstone through a cholecystenteric fistula into the proximal duodenum resulting in gastric outlet obstruction. Bouveret syndrome is a rare phenomenon that most commonly occurs in females and the elderly. A 79-year-old female presented with symptoms of gastric outlet obstruction and was diagnosed with Bouveret syndrome. This report describes the symptoms, diagnosis, and management of Bouveret syndrome, as well as its prevalence and differentiation from gallstone ileus. Patients with Bouveret syndrome present with varied, non-specific symptoms that may include emesis, abdominal pain, anorexia, and abdominal distention. Computed tomography remains the diagnostic modality of choice. Although different techniques are reported, surgical intervention is almost always required in the treatment of Bouveret syndrome.
