Background: Roux-en-Y gastric bypass (RYGB) and sleeve gastrectomy (SG) used for super obesity (SO) and super super obesity (SSO) remain controversial. The meta-analysis was to summarize the evidence.
Methods: We searched in MEDLINE and PubMed for studies concerning RYGB and SG for SO or SSO and pooled complication, percentage excess weight loss (%EWL), and resolution of comorbidities.
Results: Twelve studies were identified. RYGB achieved higher %EWL at 12 months, but no significant difference at 24 months. Resolution of diabetes mellitus and dyslipidemia reached a statistical significance; however, there was no significant difference in hypertension.
Conclusions: RYGB was superior in %EWL for SSO and SO at 12 months. However, regarding at 24 months, RYGB was equal to SG, which is from a meta-analysis and cannot be seen as a definitive conclusion.
