A rare cause of gastro-intestinal hemorrhage in a patient with a Roux-en-Y gastric bypass

Roux-en-Y胃旁路术患者胃肠出血的一个罕见原因

This case illustrates a rare cause of gastro-intestinal bleeding following bariatric surgery.Though it is essential to rule out common causes of variceal formation accompanied by intermittent,profuse bleeding,there should be a high degree of suspicion of this rare etiology in patients who have previously undergone alteration of their anatomy,especially Roux-en-Y gastric bypass(RYGB).The case emphasizes the need for a multidisciplinary medical-surgical team in evaluating and treating patients who present with complex intra-abdominal pathology.
