{Abstract}: Gallstone ileus, a rare and potentially fatal complication of cholelithiasis, occurs when gallstones breach the gastrointestinal tract through a fistula, causing an obstruction and potentially leading to severe complications. This case report details the experience of a 44-year-old woman with gallstone ileus stemming from an unnoticed cholecystoduodenal fistula following a routine cholecystectomy. The fistula was only discovered during surgery despite advanced imaging, revealing extensive adhesions. The discovery led to a subtotal cholecystectomy and fistula repair. Postoperatively, complications arose, prompting a computed tomography scan to rule out further issues. However, she later returned with gallstone ileus, necessitating a second operation. This case underscores the importance of thorough intraoperative exploration for biliary enteric fistulas during cholecystectomy, potentially averting the need for subsequent interventions. The case also highlights the diagnostic challenges of gallstone ileus and the significance of clinical suspicion.
