Superior mesenteric artery (SMA) syndrome is an uncommon cause of duodenal outlet obstruction. Symptoms and signs suggestive of this condition are nonspecific, and a high index of suspicion coupled with appropriate imaging studies are necessary for diagnosis. We present the case of a 70-year-old man who developed SMA syndrome following prolonged hospitalisation for a surgically treated bleeding duodenal ulcer. His SMA syndrome resolved after successful nonoperative management based on accepted guidelines for nutritional therapy, thus avoiding the need for reoperation and its attendant risks in a malnourished patient.
