Roux-en-Y gastric bypass (RYGB) and sleeve gastrectomy (SG) are 2 of the most widely used bariatric procedures today, in this meta-analysis, both techniques were compared for evaluating the efficacy and safety of the treatment of morbid obesity.
Materials and Methods:
Systematic literature search of Cochrane Controlled Trials Register Databases, Medline, Embase, ISI databases, and Chinese Biomedical Literature Database was performed. Statistical analyses were carried out using RevMan software.
Thirty-two recent studies including 6526 patients in total were included in this meta-analysis. Compared with SG, RYGB had significantly better effect in resolving type 2 diabetes mellitus, hypertension, hypercholesterolemia, gastroesophageal reflux disease, and arthritis. However, RYGB had higher incidence of complications and reoperation, and longer operation time than SG.
RYGB was more effective than SG in the resolution of obesity-related comorbidities, SG was a safer procedure with a reduced rate of complications and reoperation.
