Complicating factors in the management of advanced Bouveret syndrome in frail and medically complex patients: Case report and discussion of pathophysiology.

INTRODUCTION

Bouveret Syndrome is a rare but important variant of gallstone ileus with high potential for morbidity and mortality. Bouveret syndrome is a complication of gallstone disease resulting from chronic inflammation and subsequent fistulization between the gallbladder and duodenum or stomach with subsequent impaction of the stone in the proximal GI tract. Here we present a case in an elderly man with moderate medical comorbidities.

PRESENTATION OF CASE

An elderly man presented to the hospital with symptoms of gastrointestinal obstruction. Upon further diagnostic work-up, he was noted to have a 5.8 cm gallstone impacted in his proximal GI tract and thus diagnosed with a rare variant of gallstone ileus-Bouveret syndrome.

DISCUSSION

The therapeutic goal in approaching Bouveret syndrome is removal of the stone and improvement in obstruction and cholangitis. This may be accomplished with surgery or endoscopic therapy-although this may be less effective. Bouveret syndrome may have high morbidity.

CONCLUSION

Bouveret syndrome is a rare but potentially serious syndrome that should be managed accordingly. It should remain on the differential diagnosis of an elderly patient presenting with gastrointestinal obstructions, particularly if there is a history of gallstone disease and concern for proximal GI obstruction.
