Technical Tips Following 850 Consecutive One Anastomosis Gastric Bypass (OAGB) Patients

The surgical procedure One Anastomosis Gastric Bypass (OAGB) has become widely used worldwide. Since its inception, many modifications have been introduced to improve results.

The primary aim of this study was to share the modifications that we have introduced to our OAGB technique after reflecting on the problems and complications we have faced during the evolution of this procedure in our unit.

A total of 850 patients who underwent OAGB under the same surgical team at two different hospitals in the United Kingdom were displayed according to demography and comorbidities. All complications were reviewed and analysed to instigate the changes in our technique.

There were 756 (89%) primary and 94 (11%) revisional procedures. There were 596 females (70.11%) and 254 males (29.89%) in our study group. The body mass index range was 32-84 and the mean was 45. The pre-operative weight range was 89-274 kg and the mean was 126.4 kg.

With experience and reflecting on our complications we have modified our surgical approach, and these alterations have helped us to adopt OAGB as the mainstream bariatric procedure. We want to share our experience with the bariatric community for the benefit of patient care.
