Gastric colic fistula is a complication of gastric carcinoma and benign gastric ulcer. With widespread use of PPI, incidence of benign peptic ulcer disease has reduced.  The classical symptoms are abdominal pain, vomiting mostly feculent and weight loss. The best diagnostic method is the barium enema. The therapy of this condition remains surgical. We report a case of acute intestinal obstruction which was detected intra operatively to have gastrocolic fistula secondary to a benign condition.
