How it works
Mini gastric bypass works through both restriction and malabsorption. It is performed laparoscopically under general anesthesia.
Technique from IFSO, the International Federation for the Surgery of Obesity.
Compare
In the YOMEGA randomized trial of 253 patients, mini bypass was not inferior to Roux-en-Y for weight loss at five years, and nutritional status did not differ. The authors flagged a high rate of reflux after mini bypass, and 8% of mini bypass patients were converted to Roux-en-Y.

| Connections to the intestine | 1 | 2 |
| Rest of the stomach | Stays in place | Stays in place |
| Excess BMI lost at 5 years | 75.6% (YOMEGA) | 71.4% (YOMEGA) |

Yes. Mini gastric bypass, one-anastomosis gastric bypass (OAGB), single anastomosis gastric bypass and omega loop gastric bypass describe the same operation.
Mini bypass uses a long, narrow pouch and one connection to the small intestine. Roux-en-Y uses a small pouch and two connections. In both, the rest of the stomach stays in place.
IFSO reports expected weight loss of 30% to 40% of body weight, at least comparable to Roux-en-Y. In the YOMEGA trial, excess BMI loss at five years was 75.6% after mini bypass and 71.4% after Roux-en-Y.
Besides the usual surgical risks, mini bypass carries a higher risk of iron and fat-soluble vitamin deficiencies, and some patients have bloating or fatty stools. Reflux is the main concern: in the YOMEGA trial it was more common after mini bypass, and 8% of mini bypass patients were converted to Roux-en-Y within five years.
Mini gastric bypass at Renew Bariatrics is $6,299 all-inclusive, the same price as Roux-en-Y gastric bypass. Airfare is not included.
Yes, for life. IFSO advises supplementation comparable to Roux-en-Y, with extra attention to iron and the fat-soluble vitamins A, D, E and K.
