title: Gallstone ileus: clinical presentation of a benign mechanical intestinal obstruction.
abstract: Gallstone ileus is a rare cause of small bowel obstruction which usually presents in elderly female patients and which has been associated with high morbidity and mortality rates. We present the case of a 63-year-old man who presented at our institution with symptoms of bowel obstruction. Abdominal X-ray and exploratory laparotomy revealed a large gallstone in the terminal ileus.
