The demand for revisional bariatric surgery after sleeve gastrectomy (SG) has increased, but the ideal procedure remains unclear. A systematic review and meta-analysis were performed to compare the outcomes of weight loss and safety of one-anastomosis gastric bypass (OAGB) and Roux-en-Y gastric bypass (RYGB) as revisional procedures for failed SG. Four retrospective comparative studies were included, comprising 499 individuals. Patients submitted to OAGB had a more significant total weight loss (TWL) (MD = - 5.89%; 95% CI - 6.80 to - 4.97) after revisional surgery. Overall early complication rate was similar between procedures (RD = 0.04; 95% CI: - 0.05 to 0.12). Limited and heterogeneous data prevent meaningful conclusions, but the present analysis suggests that OAGB has a better TWL after revisional surgery.
