Mixed
Roux-en-Y Gastric Bypass (RYGB) and Sleeve Gastrectomy (SG) are highly effective surgical interventions for severe obesity, with RYGB showing slightly greater long-term weight loss.
Surgical options like RYGB and SG are highly effective for severe obesity, leading to 47-55% excess weight loss over seven years. RYGB tends to result in slightly greater weight loss than SG, but both improve quality of life. These are major surgeries requiring careful patient selection and postoperative management.
StrongSupportsHIGH confidence
Surgical techniques like Roux-en-Y gastric bypass (RYGB) and sleeve gastrectomy (SG) achieve 27–69% excess weight loss (EWL)... The mean percentage of excess weight loss (%EWL) after seven years was 47% (95% CI, 43%-50%) in the LSG group and 55% (95% CI, 52%-59%) in the LRYGB group, resulting in a difference of 8.7 percentage points (95% CI, 3.5-13.9) favoring LRYGB
