A case of Bouveret's syndrome treated with gastrojejunal anastomosis

Endoscopic and surgical management of Bouveret's syndrome complicated by gallstone ileus

Bouveret’s syndrome is a rare complication that occurs most commonly in elderly patients with multiple comorbidities. It is secondary to an impacted gallstone causing gastric outlet obstruction from a cholecystoduodenal fistula, and there is no defined standardized management in current literature. A 92-year-old woman presents to our tertiary community hospital with abdominal discomfort concerning for bowel obstruction. Computed tomography revealed pneumobilia with a cholecystoduodenal fistula and a large gallstone in the proximal duodenum causing gastric outlet obstruction. The impacted gallstone failed endoscopic extraction with electrohydraulic lithotripsy, and patient subsequently developed distal gallstone ileus requiring exploratory laparotomy and enterolithotomy. This case report examines the need for early coordinated endoscopic and surgical management of a patient with Bouveret’s syndrome complicated by gallstone ileus as it is associated with high morbidity and mortality rates.

Bouveret's syndrome: a strategic approach for management

An 81-year-old woman, diabetic and hypertensive, presented with nausea and intermittent vomiting. She had dysphagia and loss of appetite for over 6 weeks and significant weight loss over 3 weeks and was admitted in general surgery unit on emergency basis. Investigations revealed dilated stomach and a stone in first part of duodenum, with probable site of obstruction at level of first part of duodenum, secondary to a cholecystoduodenal fistula. With a preoperative diagnosis of Bouveret's syndrome, she underwent laparotomy and subtotal cholecystectomy. Postoperative recovery was delayed due to gastroparesis and delayed gastric emptying which resolved with conservative management. Successful management of this case required a multidisciplinary team approach. Early diagnosis was the key to management. Mode of treatment and management of Bouveret's syndrome should be tailored to suit patient's age, comorbidities and performance status.
