Abstract

Eighteen studies were reviewed to compare the safety and efficacy of Roux-en-Y gastric bypass, one anastomosis gastric bypass, and single anastomosis duodeno-ileal bypass with sleeve gastrectomy.

  • SADI-S showed greater weight loss at 5 years compared to other procedures.
  • OAGB demonstrated better weight loss outcomes at 10 years.
  • SADI-S was associated with a better resolution of diabetes.
  • OAGB resulted in improved resolution of hypertension and dyslipidemia.
  • Early complications and mortality rates were higher for SADI-S.
  • RYGB had more frequent late complications compared to SADI-S.
