Benign gastrocolic fistula is unusual, although it has been demonstrated in patients who took steroids and developed peptic ulcer disease. Surgical management traditionally has been employed. In this report, we present an aged cerebrovascular accident patient in vegetative status who had been treated by long-term corticosteroid for systemic lupus erythematosus, with history of recurrent gastric ulcer bleeding. The patient received periodical nasogastric tube replacement for one year. She was brought to us for evaluation of acute diarrhea. A gastrocolic fistula presumably resulting from nasogastric tube penetration was identified. Endoscopic hemoclipping was applied and proton pump inhibitor was prescribed. The gastrocolic fistula healed ten days later. The patient remained well 24 months following initial diagnosis.
