Bouveret’s syndrome is a rare condition characterized by gastric outlet obstruction from an ectopic gallstone, facilitated by aberrant connection of the biliary and luminal gastrointestinal tracts. Establishing a diagnosis of Bouveret’s syndrome can be aided by clinical, radiologic, and endoscopic assessments and importantly relies on prompt diagnosis and management. Despite its rarity, the disease confers a high rate of morbidity and mortality. We therefore aimed to provide a review of the literature to enhance awareness of this phenomenon to broaden the differential diagnosis of gastric outlet obstruction and subsequent management of this particular—and peculiar—etiology.
