Meckel's diverticulum complicating gallstone ileus-a surgical odyssey: case report and literature review

Meckel's diverticulum is a common anomaly of the gastrointestinal tract, often presenting with various complications. Here, we present a case of a 50-year-old female with a history of hysterectomy and cesarean sections, who presented with symptoms consistent with gallstone ileus. Upon investigation, a Meckel's diverticulum with an associated cholecystoduodenal fistula was identified. Surgical intervention involved resection of the affected intestinal segment and anastomosis, without additional intervention targeting the gallbladder or fistula repair. A systematic review revealed four reported cases of Meckel's diverticulum complicating gallstone ileus in the literature. Our case underscores the importance of considering Meckel's diverticulum in the differential diagnosis of gallstone ileus and highlights the efficacy of a tailored surgical approach.
