| Abstract: | Literature search was performed for bariatric surgery from inception to September 2013, in which the effects of laparoscopic Roux-en-Y gastric bypass (LRYGB) and laparoscopic sleeve gastrectomy (LSG) on body mass index (BMI), percentage of excess weight loss (EWL%), and diabetes mellitus (DM) were compared 2 years post-surgery. A total of 9,756 cases of bariatric surgery from 16 studies were analyzed. Patients receiving LRYGB had significantly lower BMI and higher EWL% compared with those receiving LSG (BMI mean difference (MD)?=??1.38, 95 % confidence interval (CI)?=??1.72 to ?1.03; EWL% MD?=?5.06, 95 % CI?=?0.24 to 9.89). Improvement rate of DM was of no difference between the two types of bariatric surgeries (RR?=?1.05, 95 % CI?=?0.90 to 1.23). LRYGB had better long-term effect on body weight, while both LRYGB and LSG showed similar effects on DM. |
