Roux-en-Y Gastric Bypass Vs Sleeve Gastrectomy in Super Obesity: a Systematic Review and Meta-Analysis.

Laparoscopic Roux-en-Y gastric bypass (LRYGB) and laparoscopic sleeve gastrectomy (LSG) are safe procedures that may present sub-optimal results in superobesity (SO). A meta-analysis was performed aiming to summarize the available evidence on weight loss (primary outcome) and comorbidities resolution of LRYGB and LSG in patients with SO (BMI ≥ 50 kg/m). From the 16 included studies, 7 integrated the meta-analysis.
