Background: We previously described sleeve gastrectomy with jejunoileal bypass (SGJIB) as promising novel technique for the surgical treatment of obesity Methods: A retrospective analysis of a prospective database in a Private Practice of Alimentary Tract Surgery in São Paulo, Brazil. We analyzed 176 patients with 60 months of follow-up, 74 of whom underwent Vertical Sleeve Gastrectomy with Jejunoileal Bypass (VSG-JIB) (50 women and 24 men) with a mean age of 38 years and a mean body mass index (BMI) of 40 kg/m 2 , and 102 patients underwent Roux-en-Y gastric bypass (RYGB) (90 women and 12 men) with a mean age of 36.5 years and a mean BMI of 39.73 kg/m 2 . Results: There was no statistically significant difference in long-term weight loss between the two groups. The rate of postoperative complications immediately after surgery was similar, but there was a tendency toward less severe complications in the SGJIB cohort. Conclusion: Sleeve gastrectomy with jejunoileal bypass is a novel surgical procedure for weight loss with comparable efficacy and safety compared with laparoscopic RYGB.
