Abstract
Despite the current increase in revisional bariatric surgery (RBS), data on the sustainability of weight loss remain unclear. A systematic review and meta-analysis were performed to assess weight loss outcomes in adult patients undergoing RBS with follow-up > 2 years. Twenty-eight observational studies (n = 2213 patients) were included. The %TWL was 27.2 (95%CI = 23.7 to 30.6), and there was a drop in BMI of 10.2 kg/m2 (95%CI = - 11.6 to - 8.7). The %EWL was 54.8 (95%CI = 47.2 to 62.4) but with a high risk of publication bias (Egger's test = 0.003). The overall quality of evidence was very low. Our data reinforce that current evidence on RBS is mainly based on low-quality observational studies, and further higher-quality studies are needed to support evidence-based practice.
