Abstract

The mini-gastric bypass (MGB), which originated in 1997 as a simple, rapid, and mainly malabsorptive bariatric operation, is now increasing internationally. A variant of the MGB, started in Spain in 2002 with an anti-reflux mechanism, is called the one-anastomosis gastric bypass (OAGB or BAGUA); the OAGB is also commonly performed in Mexico and Latin America. The MGB and OAGB have increased over the years and now make up the third most common bariatric operations worldwide (and the most common gastric bypasses in many countries). Reports show them to be superior operations with respect to safety, short learning curve, resolution of comorbidities (especially diabetes), excellent quality of life, and durable weight loss. Revision or reversal can be readily performed. We present the methods and rationale of the MGB-OAGB.
