It is with great interest that we have read the letter to the editor in this issue. This was from Liagre et al., in response to our study.
We conducted a randomized controlled trial (RCT) on the revisional Roux-en-Y gastric bypass (RYGB) versus revisional one-anastomosis gastric bypass (OAGB) after failed sleeve gastrectomy (SG). For example, in a study of the 10-year outcomes following OAGB and RYGB [2], significantly better weight loss results were reported in the OAGB group percentage of excess weight loss (EWL%) 71.1% vs. 80.1% (p= <0.001). In both groups, revision surgery was not significantly different (19.3% for RYGB and 17.3% for the OAGB), and the EWL% at 10 years was not split into primary or revisional surgery. However, in the RYGB, 2.4% of the revision surgery was Mason gastric bypass surgery vs. 0.2% in the OAGB. It is known that Mason gastric bypass surgery has an increased adhesions profile and the potential for worse treatment outcomes, with good gastric pouch preparation not always being possible.
