Abstract
In recent years, combined restrictive and hypo-absorptive procedures have gained widespread acceptance. The rationale of this systematic review is to compare the safety and efficacy between Roux-en-Y gastric bypass (RYGB), one anastomosis gastric bypass (OAGB) and single anastomosis duodeno-ileal bypass with sleeve gastrectomy (SADI-S). Eighteen eligible studies were finalized for this review. Weight loss outcomes were greater with SADI-S (5 years) and OAGB (10 years). SADI-S offered better resolution of diabetes whereas hypertension and dyslipidaemia resolution were better with OAGB. Although early complications and mortality were higher with SADI-S, late complications were more frequent with RYGB. Both SADI-S and OAGB are as effective as RYGB for weight loss, but OAGB offers lesser complications. However, more data is imperative to determine the next gold standard procedure.
