From the Guidelines
Proton pump inhibitors (PPIs) are recommended for most gastric bypass patients to prevent marginal ulcers, with a suggested dose of omeprazole 40mg or equivalent daily for the first 3-6 months post-surgery. The use of PPIs in gastric bypass patients is supported by recent guidelines, which suggest that prophylactic use of PPIs can reduce the incidence of marginal ulcers, particularly when used for longer durations such as 3 months 1.
Key Considerations
- The incidence of marginal ulcers after gastric bypass surgery can range from 0.6 to 16%, and PPIs can help reduce this risk 1.
- PPIs should be taken in higher doses than standard after gastric bypass surgery due to reduced uptake 1.
- Common PPIs include omeprazole, esomeprazole, pantoprazole, and lansoprazole, with dosing typically once daily before the first meal.
- Patients should be monitored for side effects and nutritional deficiencies, with appropriate supplementation as needed, as long-term PPI use carries risks including vitamin B12 deficiency, calcium malabsorption, and increased fracture risk.
Management of Marginal Ulcers
- Marginal ulcers are classified into early and late ulcers, with early ulcers more likely to be associated with local factors and late ulcers related to increased acid exposure over time 1.
- Treatment of marginal ulcers typically consists of a minimum of 3 to 6 months of PPI therapy, elimination of potential risk factors, and regular endoscopic control to monitor healing and rule out stenosis 1.
- Recurrent marginal ulcers refractory to medical therapy may require revisional surgery, which consists of resection and reconstruction of the gastro-jejunal anastomosis with or without partial remnant gastrectomy 1.

From the Research
Guidelines for Using Proton Pump Inhibitors (PPIs) in Gastric Bypass Patients
- The use of PPIs in gastric bypass patients is a common practice to prevent marginal ulcers after Roux-en-Y gastric bypass (RYGB) surgery 2.
- Studies have shown that PPIs can reduce the incidence of marginal ulcers, but the evidence is not conclusive 2.
- A retrospective study found that patients who received prophylactic PPIs after RYGB had a lower incidence of marginal ulcers, but the difference was not statistically significant 2.
- Another study found that continuous use of PPIs increased from baseline to 4 years after sleeve gastrectomy (SG) and gastric bypass (GBP), with SG patients being more likely to continue PPI therapy 4 years after surgery 3.
Risk Factors for PPI Use in Gastric Bypass Patients
- SG compared to GBP, higher body mass index, and preoperative antidepressant treatment are major risk factors for medium-term continuous PPI therapy 3.
- Nicotine abuse, NSAIDs, and H. pylori do not appear to influence the incidence of marginal ulcers 2.
- PPI-induced hypomagnesemia is a concern, but a study found that the risk of hypomagnesemia during 1 year of prophylactic PPI use after RYGB is minimal 4.
Optimal PPI Administration in Gastric Bypass Patients
- Opened PPI capsules (OCs) may be absorbed more easily than intact capsules (ICs) in patients with gastric bypass, due to the small gastric pouch and rapid small-bowel transit 5.
- A retrospective study found that patients with marginal ulceration who received OC PPIs had shorter ulcer healing times, fewer endoscopic procedures, and used less healthcare resources compared to those who received IC PPIs 5.
- The use of OC PPIs is a low-risk, low-cost alternative that should be considered for patients with marginal ulceration after RYGB 5.
