There is little robust data on weight regain (WR) after bariatric surgery making it difficult to counsel patients regarding long-term outcomes of different bariatric procedures. The purpose of this study was to see WR in medium and long term after SG, RYGB, and OAGB in Indian population.
In a multicentre study, data on preoperative and postoperative weights over 5 years were collected. Multiple definitions were applied to find the proportion of patients with significant WR increase of 25% of lost weight from nadir (definition 1), weight gain of > 10 kg from nadir (definition 2), and BMI gain of > 5 kg/m2 from nadir (definition 3). The proportion of those with significant WR was compared across sub-groups.
A total of 9617 patients were included. Median WR at 5 years was 14.1% of lost weight, 1.92 kg/m2, and 5 kg. Significant WR using definition 1 was 35.1%, 14.6%, and 3% after sleeve gastrectomy (SG), Roux-en-Y gastric bypass (RYGB), and mini-one anastomosis gastric bypass (OAGB) respectively. Severe albumin deficiency was highest in OAGB (5.9%) patients followed by SG (2.9%) and RYGB (2.2%) at 5 years(p = 0.023). Haemoglobin levels < 10 g/dL were seen in 8.2%, 9.0%, and 13.9% of SG, RYGB, and OAGB patients respectively (p = 0.041).
In the first comparative study of WR, OAGB had lesser WR in comparison to SG and RYGB but had the most impact on Hb and albumin levels in the long term. Definition selection for reporting WR has a significant impact on the results. There is a need for standardising the reporting of WR in bariatric literature.
