Systematic Review and Meta-analysis of the Effects of Laparoscopic Roux-en-Y Gastric Bypass and Laparoscopic Sleeve Gastrectomy on Dyslipidemia

AbstractThe aim of this meta-analysis was to compare the effects of LRYGB and LSG on dyslipidemia. Studies comparing the effects of LRYGB and LSG on dyslipidemia with follow-up of 12 months or more were included. Twenty-four studies comprising seven RCTs and 17 comparative observational studies were included. Meta-analysis of RCTs (n=487) showed that improvement/resolution of dyslipidemia was better after LRYGB (68.5%,n=161/235) compared to LSG (48.4%,n=122/252). Patients undergoing LRYGB were more than twice as likely to experience improvement/resolution in dyslipidemia compared to those undergoing LSG (OR 2.28, 95% CI 1.21 –4.29,p=0.010). Both LRGYB and LSG appears effective in improving dyslipidemia at>12 months after surgery; however, this improvement is more than twice higher after LRYGB compared to LSG.
