Abstract: Gall stone ileus is complication of cholithiasis. It is rare and seen in aged patients diagnosed as cholelithiasis with co morbidities. High index of suspicion is necessary for arriving at a clinical diagnosis. Contrast enhanced computed tomography is diagnostic. Enterolithotomy followed by closure of the fistula with cholecystectomy as a two staged procedure is the safest approach for managing gall stone ileus.
