Gallstone ileus of the duodenum: an unexpected presentation of Bouveret's syndrome

This report describes a patient who presented with a large gallstone obstructing the duodenal bulb, with the chief complaint of acute on chronic abdominal pain. Classically, this is known as Bouveret's syndrome or a gallstone ileus of the duodenum. Our patient's current health status presented a challenge, with the presence of several comorbidities, particularly a large abdominal aortic aneurism. We chose an open procedure for this reason. The stone was removed through a laparotomy, and the cholecystoduodenal fistula that the stone used to pass into the small bowel was repaired. With our patient's future medical needs in mind, only the necessary interventions were performed to regain functionality of the bowel. This came in the form of a diverting gastrojejunostomy, with a distal jejunostomy and feeding tube inserted. The patient tolerated the procedure well, only remaining intubated postoperative due to her chronic obstructive pulmonary disease (COPD). She achieved a complete recovery and transitioned home.
