Laparoscopic one anastomosis gastric bypass for the revision of failed laparoscopic sleeve gastrectomy

Abstract

Introduction Sleeve gastrectomy is gaining more and more popularity among bariatric procedures; however, there is an increasing number of cases with insufficient loss of weight or weight regain after sleeve gastrectomy. Many operations can be used to revise the failed sleeve gastrectomy, and one of them is one anastomosis gastric bypass (OAGB). This study aims to assess the efficiency of the conversion of laparoscopic sleeve gastrectomy to laparoscopic OAGB. Patients and methods This is a prospective study that included 16 patients with failed sleeve gastrectomy who underwent revisional OAGB. This study was conducted in Ain Shams University Hospitals from August 2016 to December 2018. Results The mean age of the patients was 40.18±7.6 years. At least 24 months separated the sleeve gastrectomy from the revisional OAGB (24–82), with a mean of 49.4±14.4 months. The mean;Deg;BM;Deg;I at conversion was 46.1± 7 kg/m2. At 12 months after the revisional OAGB, the mean;Deg;BM;Deg;I was 33.5± 4 kg/m2. There were four cases of intraoperative complications; however, there were no mortalities. Conclusion OAGB after failed sleeve gastrectomy is feasible, leading to significant loss of weight and improvement in comorbidities, with minimal perioperative complications.
