Mini Gastric Bypass
The mini gastric bypass (MGB), also called single anastomosis gastric bypass (SAGB), involves creating a long, narrow stomach pouch and connecting it to the small intestine approximately 150–200 cm from the start of the jejunum using a single connection (anastomosis). This simplifies the traditional Roux-en-Y bypass while maintaining significant weight loss and metabolic benefits.
With only one intestinal connection instead of two, the mini bypass involves a shorter operative time and technically simpler surgical steps compared to Roux-en-Y gastric bypass — while producing comparable weight loss outcomes in appropriate candidates.
Candidacy for mini bypass is evaluated carefully. Patients with significant gastroesophageal reflux (GERD) are generally not candidates, as the single connection design carries a different reflux risk profile than Roux-en-Y.
Who Is a Candidate?
BMI typically 35–55
Patients seeking bypass-level metabolic effects with a simplified surgical technique
No significant history of gastroesophageal reflux (GERD) that would contraindicate the procedure
Cleared as appropriate candidates by our bariatric team after full evaluation
Commitment to lifelong vitamin supplementation and dietary follow-up
All procedures require a clinical evaluation to confirm candidacy. The information on this page is for educational purposes only and does not constitute medical advice.

Why Russald Medical Center
Shorter Operative Time Than Standard Bypass
The single anastomosis design reduces operative time compared to Roux-en-Y — which translates to less time under general anesthesia. For appropriate candidates, this is a meaningful clinical advantage.
Bypass-Level Weight Loss Results
Mini gastric bypass produces 70–80% excess weight loss in typical candidates — comparable to Roux-en-Y gastric bypass — while offering a technically simplified procedure.
65–75% Less Than US Hospital Rates
Bariatric surgery in the United States is expensive and often not covered by insurance for this procedure type. Russald Medical Center delivers the same technique at a significantly lower cost.
Careful Candidacy Screening
Not every patient is appropriate for mini bypass — GERD history, anatomy, and prior procedures all affect candidacy. Our team evaluates each case individually and will recommend the best-fit procedure for your profile.
Supplement Protocol Provided
Lifelong vitamin supplementation is required after mini bypass, as with all bypass procedures. Your care team provides a complete protocol at discharge.
20 Minutes from San Diego
Russald Medical Center is approximately 20 minutes from the San Diego border crossing. Mini bypass typically requires a 3–4 day trip from the US.

The right choice depends on your anatomy, reflux history, and clinical profile — determined during evaluation.
Patients with a BMI of approximately 35–55, without significant GERD, who are seeking bypass-level results. Final candidacy is determined by our bariatric team after full evaluation including your medical history and clinical profile.
Yes, when performed by an experienced bariatric surgeon and with appropriate patient selection. As with all bariatric procedures, risks are reviewed in detail during your consultation. Patient selection is critical — we do not perform mini bypass on patients who are not suitable candidates.
Mini gastric bypass at Russald Medical Center costs 65–75% less than US bariatric centers — about $5,500–$7,500 versus $18,000–$28,000 in the US without insurance. Your exact price is confirmed in a personalized quote after your evaluation.
Yes. Lifelong vitamin supplementation is required after mini bypass due to the bypass component of the procedure. Your care team provides a complete supplement protocol at discharge.
