Abstract

We aim to review the available literature on obese patients treated with one-anastomosis gastric bypass (OAGB) or laparoscopic sleeve gastrectomy (LSG), in order to compare the clinical outcomes and intraoperative parameters of the two methods. A systematic literature search was performed in PubMed, Cochrane Library, and Scopus databases, in accordance with the PRISMA guidelines. Seventeen studies met the inclusion criteria incorporating 6761 patients. This study reveals increased weight loss, remission of comorbidities, shorter mean hospital stay, and lower mortality in the OAGB group. The incidence of leaks and intra-abdominal bleeding was similar between the two approaches. Well-designed, randomized controlled studies, comparing LSG to OAGB, are necessary to further assess their clinical outcomes.
