Gallstone ileus is an uncommon complication of gallstones and a rare cause of intestinal obstruction. Typically as a result of the formation of cholecystoduodenal fistula, surgical removal of the gallstone is the mainstay of treatment in order to relieve the intestinal obstruction. A 34-year-old male with no history of cholelithiasis presented with features of a small bowel obstruction. CT scan of the abdomen demonstrated pneumobilia, a cholecystoduodenal fistula and small bowel obstruction, features suspicious for a gallstone ileus. The patient underwent a laparotomy and removal of two gallstones via an enterotomy. He was discharged home after an uneventful post-operative period. Gallstone ileus is an uncommon cause of mechanical bowel obstruction with often delayed presentation and non-specific symptoms. A high level of suspicion is required in at-risk groups, and in patients presenting with a bowel obstruction and known gallstone disease.
