Laparoscopic Roux-en-Y gastric bypass offers superior weight loss

At five years post-surgery, laparoscopic Roux-en-Y gastric bypass (LRYGB) achieved significantly greater weight loss compared to laparoscopic sleeve gastrectomy (LSG) with a mean difference of -7.65 kg/m² (p=0.0001). The LRYGB group also exhibited better resolution rates for type 2 diabetes mellitus (T2D) and dyslipidemia. Although both procedures showed no difference in quality of life or remission of hypertension, LSG had a lower morbidity rate and no significant difference in mortality was observed between the two.

• Why it matters: Laparoscopic sleeve gastrectomy vs. Roux-en-Y gastric bypass outcomes unclear.
