Bouveret syndrome

Abstract

Gastric outlet obstruction secondary to an impacted duodenal gallstone, or Bouveret syndrome, is a rare variant of gallstone ileus. It is most common in elderly women and frequently requires endoscopic or surgical management. We present the case of an 80-year-old woman with multiple medical comorbidities who presented to our service with 2 weeks of abdominal pain and nausea. MRI revealed a 4.4-cm gallstone impacted in the duodenum with associated cholecystoduodenal fistula. She required operative exploration to remove the impacted stone and had an unremarkable post-operative course. This case demonstrates the presentation and workup of this rare disorder and the various options for treatment, which can sometimes be difficult given the typical age and associated comorbidities of the patient.
