Impact of Restrictive (Sleeve Gastrectomy) vs Hybrid Bariatric Surgery (Roux-en-Y Gastric Bypass) on Lipid Profile

Background Few studies have evaluated the impact of hybrid versus purely restrictive bariatric surgery on lipid profile, with the results being contradictory. The effect of laparoscopic sleeve gastrectomy (LSG) and laparoscopic Roux-en-Y gastric bypass (LRYGB) on lipid profile was compared. Methods A nonrandomized prospective cohort study was conducted on severely obese patients undergoing bariatric surgery. Indication for the type of surgical procedure was based on clinical criteria. Patients on lipid-lowering drugs and those that could not be matched for age, sex, and body mass index were excluded. Finally, 51 patients who underwent LSG and 51 undergoing LRYGB completed this study. Results During the first year post-surgery, no differences in percentage of excess weight loss and triglyceride reduction were found between groups. After LRYGR, low-density lipoprotein (LDL) cholesterol concentrations fell significantly (125.9 ± 29.3 to 100.3 ± 26.4 mg/dl, p
