Mini Gastric Bypass
The mini gastric bypass (also called single-anastomosis or one-anastomosis gastric bypass) creates a long, narrow stomach pouch and a single connection to the small intestine — a technically simpler alternative to Roux-en-Y. It delivers weight-loss and metabolic results comparable to traditional bypass, with shorter operating time, fewer connections, and a generally smoother recovery.
The Process
Pre-operative Assessment
Standard bariatric workup confirms candidacy. Mini bypass is often preferred for patients seeking strong results with a shorter, less complex operation.
Single-Anastomosis Surgery
The 60–90 minute laparoscopic procedure creates a long gastric pouch and connects it to the small intestine in a single loop — eliminating one of the two connections of traditional bypass.
Faster Recovery
Most patients leave the hospital after 1–2 nights and return to office work within 1–2 weeks. The staged diet mirrors other bariatric procedures.
Long-Term Outcomes
Expected weight loss is 65–75% of excess weight over 12–18 months, with strong improvements in diabetes, hypertension, and lipid profile.
