Impact of laparoscopic Roux-en-Y Gastric bypass versus sleeve gastrectomy on postoperative lipid values

Abstract Background Metabolic surgery has been shown to significantly improve many obesity-related co-morbidities, including dyslipidemia. The literature has produced mixed results comparing postoperative lipid values after laparoscopic Roux-en-Y gastric bypass (LRYGB) compared to laparoscopic sleeve gastrectomy (LSG); with some indicating significantly greater reductions in total cholesterol and low-density lipoprotein (LDL) in LRYGB versus LSG, and others reporting no significant differences. Objectives To evaluate the postoperative lipid values after LRYGB versus LSG at a community hospital. Setting Integrated multispecialty health system with a community teaching hospital. Methods A retrospective review of our prospective database was completed to identify patients who underwent either LRYGB or LSG at our institution from 2001 through 2013. Lipid values available at 6–18 months postoperative were evaluated. Statistical analysis included χ2 and Wilcoxon rank-sum tests. A P value
