Abstract

The One Anastomosis (Mini) Gastric Bypass is rapidly gaining acceptance. This review reports cumulative results of 12,807 procedures in obese patients with a mean age of 41.18 years and BMI of 46.6 kg/m2. The overall mortality was 0.10% and the leak rate was 0.96%. The follow-up duration ranged from 6 months to 12 years. A marginal ulceration rate of 2.7% and an anaemia rate of 7.0% were reported. Approximately 2.0% of patients reported postoperative gastro-oesophageal reflux and 0.71% developed malnutrition. Excess weight loss at 6, 12, 24 and 60 months was 60.68, 72.56, 78.2 and 76.6% respectively. Type 2 diabetes mellitus and hypertension resolved in 83.7 and 66.94% respectively. We conclude that there is now sufficient evidence to include MGB-OAGB as a mainstream bariatric procedure.
