title: Giant jejunal ulcers after Roux-en-Y gastric bypass.
abstract: We describe the clinical and radiographic findings in two patients who developed giant, intractable ulcers in the jejunal Roux limb after gastric bypass surgery, most likely secondary to chronic jejunal ischemia. The diagnosis of such ulcers is important because of the need for aggressive medical or surgical treatment of these patients.
