Bouveret's syndrome: a report of two cases

Authors

Abstract

Introduction
Bouveret's syndrome, a rare and clinically challenging condition, is a variant of gall stone ileus caused by impaction of a large gallbladder stone in the duodenum secondary to a cholecystoduodenal fistula.
Case presentation
We present two cases of duodenal obstruction in old patients due to gall stone migration and impaction in the duodenum. Both were treated surgically.
Discussion
Bouveret's syndrome is a rare variant of gall stone ileus. Risk factors include old age, female sex, large-sized stones, and long history of gall stone disease. Treatment options include extracorporeal shock wave lithotripsy, endoscopy, and surgery.
Conclusion
Bouveret's syndrome is a clinically challenging diagnosis to make. Although surgical stone extraction remains the classic treatment option with the least failure rates, leaving the fistula alone is associated with the least morbidity and mortality rates.
