CONTEXT: Causal factors of gastrojejunal ulcers after Roux-en-Y gastric bypass include peptic acid secretion from the gastric pouch. Esomeprazole is a potent inhibitor of acid secretion. OBJECTIVE: To assess the occurrence of dyspepsia and gastrojejunal ulcers within the first 2 months after Roux-en-Y gastric bypass during the use of esomeprazole. METHODS: One hundred eighteen morbid obese subjects were submitted to Roux-en-Y gastric bypass. Preoperative upper gastrointestinal tract endoscopy was negative for H. pylori. All subjects received esomeprazole for 60 days after surgery. RESULTS: Two weeks after surgery only 13 mild symptoms were reported. After 2 months, 17 also moderate complaints were registered. Endoscopy around the 60th day showed esophagitis in 10 (8.5%), hiatal hernia in 2 (1.7%), foreign body in the anastomotic line in 12 (10.2%) and gastrojejunal ulcers was observed in 9 (7.6%) subjects, 2 of which had a suture material or metallic staple granuloma in the gastrojejunostomy. Ten subjects took nonsteroidal anti-inflammatory drugs at least once during study, but none of them developed ulcer. None of the subjects with ulcer had dyspeptic symptoms. CONCLUSION: The incidence of ulcer in the gastrojejunal anastomosis within the first 2 months following Rouxen-Y gastric bypass under proton pump inhibitors is considerable. It was not related to the use of non-steroidal anti-inflammatory drugs, highlighting the possibility of ischemia and foreign body as causal factors. The ulcers were asymptomatic, and all post-surgical dyspeptic symptoms were moderate in severity.
