Abstract

Background: Laparoscopic sleeve gastrectomy (LSG) is the most commonly performed bariatric procedure, while laparoscopic adjustable gastric banding (LAGB) has been for a decade one of the most popular interventions for weight loss. After LSG and LAGB, some patients may require a second surgery due to weight regain or late complications. One anastomosis gastric bypass (OAGB) is a promising bariatric procedure, which provides effective long-term weight loss and has a favorable effect on type 2 diabetes. Objectives: To retrospectively analyze data from 10 Italian centers on conversion from LAGB and LSG to OAGB. Setting: High-volume centers for bariatric surgery. Methods: Prospectively collected data from 10 high-volume centers were retrospectively reviewed. Body mass index (BMI), percentage of excess BMI loss, reasons for redo, remission from co-morbidities (hypertension, diabetes, gastroesophageal reflux, and dyslipidemia), and major complications were recorded. Results: Three hundred patients were included in the study; 196 patients underwent conversion from LAGB to OAGB and 104 were converted from LSG. BMI was 45.1 ± 7 kg/m2 at the time of first intervention, 41.8 ± 6.3 kg/m2 at redo time, and 30.5 ± 5.5 kg/m2 at last follow-up appointment. Mean percentage of excess BMI loss was 13.2 ± 28.2 at conversion and 73.4 ± 27.5 after OAGB. Remission rates from hypertension, diabetes, gastroesophageal reflux, and dyslipidemia were 40%, 62.5%, 58.7% and 52%, respectively. Mean follow-up was 20.8 (range, 6–156) months and overall complications rate was 8.6%. Conclusion: Our data show that OAGB is a safe and effective revisional procedure after failed restrictive bariatric surgery.
