Introduction The comparative efficacy of various bariatric procedures has not been completely elucidated. We aimed to evaluate efficacy and safety of various bariatric procedures comprehensively. Methods We searched for randomized controlled trials investigating the efficacy of bariatric surgery. Network meta-analyses were performed to determine the percentage of excess weight loss (%EWL) and remission of diabetes mellitus (DM). Results Of 45 studies, 33 and 24 provided the data for %EWL and DM remission rates, respectively. Six months after surgery, biliopancreatic diversion with duodenal switch (BPD-DS), Roux-en-Y gastric bypass (RYGB), and sleeve gastrectomy (SG) showed superior efficacy for %EWL compared to the standard-of-care (mean difference [MD], [95% confidence interval [CI]]: BPD-DS, 38.2% [7.3%, 69.1%]; RYGB, 32.1% [3.1%, 61.1%]; SG, 32.5% [5.5%, 59.5%]). However, adjustable gastric banding was not superior to standard-of-care (MD [95% CI] = -0.2% [-19.6%, 19.2%]). At 1 year, all bariatric procedures were superior to standard-of-care. At 3 years, RYGB and SG showed superior efficacy when compared to standard-of-care (MD [95% CI]: RYGB, 45.0% [21.8%, 68.2%]; SG, 39.2% [15.2%, 63.3%]). With respect to DM remission 3-5 years after surgery, BPD-DS, RYGB, and SG were superior to standard-of-care. Hernias, obstruction/stricture, bleeding, and ulcers were less common in patients who underwent SG than in those who underwent RYGB. Conclusions RYGB and SG had excellent long-term outcomes for both the %EWL and DM remission rates. Additionally, SG had a relatively lower risk of adverse events than RYGB.
