Assessment of acid exposure in the stomach in gastric bypass patients with anastomotic ulcer: insights into pathologic acid exposure

Background: Anastomotic ulcer following Roux-en-Y gastric bypass affects 16% of patients. Risk factors such as cigarette smoking and NSAIDs/steroids use do not fully account for all cases. We postulate excessive acid exposure to be a culprit. We studied the acid exposure of gastric pouch in patients presenting with recurrent ulcer disease following gastric bypass.
