Summary: | Objective
This study aimed to determine which bariatric procedure allows patients to obtain the best weight‐loss outcomes and a remission of type 2 diabetes.
Methods
Databases were searched for randomized‐controlled trials comparing Roux‐en‐Y gastric bypass (RYGB) with sleeve gastrectomy (SG) or one‐anastomosis gastric bypass (OAGB). The mean difference (MD) or the relative risk was determined.
Results
Twenty‐five randomized‐controlled trials were analyzed. Excess weight loss (EWL, percentage) was greater for RYGB patients at 3 years (MD: 11.93, p < 0.00001) and 5 years (MD: 13.11, p = 0.0004). Higher excess BMI loss (percentage) was found in RYGB at 1 year (MD: 11.66, p = 0.01). Total weight loss (percentage) was greater for RYGB patients after 3 months (MD: 2.41, p = 0.02), 6 months (MD: 3.83, p < 0.00001), 1 year (MD: 6.35, p < 0.00001), and 5 years (MD: 3.90, p = 0.005). No difference in terms of remission of type 2 diabetes was seen between RYGB and SG. EWL was significantly more important after OAGB than after RYGB after 1 year (MD: −10.82, p = 0.003).
Conclusions
RYGB is more efficient than SG in the midterm. OAGB offers greater EWL than RYGB after 1 year, but further evidence is needed to confirm this result. |
