ObjectiveTo investigate the short-term efficacy of laparoscopic sleeve gastrectomy (LSG) for obesity with type 2 diabetes mellitus (T2MD) in China. MethodsClinical randomized controlled trial literatures about domestic LSG treatment of obesity with T2MD were obtained from Wanfang Data, China Knowledge Resource Integrated Database, PubMed and Web of Science English Data. The literatures were selected according to the inclusive and exclusive criteria, then evaluated. Methodological quality assessment and meta analysis were evaluated according to the data extracted from those literatures. The short-term efficacy (fasting blood glucose or glycosylated hemoglobin) was evaluated after operation. ResultsOne hundred and seven patients performed LSG were retrieved from 7 literatures. The levels of fasting blood glucose and glycosylated hemoglobin on the postoperative 6 months were all obviously decreased as compared with the levels before operation (fasting blood glucose:MD=2.99, 95% CI 2.39-3.60, P < 0.000 01; glycosylated hemoglobin:MD=2.24, 95% CI 1.43-3.04, P < 0.000 01), which on the postoperative 12 months were all obviously decreased as compared with the levels on the postoperative 6 months (fasting blood glucose:MD=0.56, 95% CI 0.16-0.95, P=0.006; glycosylated hemoglobin:MD=0.52, 95% CI 0.22-0.81, P=0.000 6). The postoperative fasting blood glucose and glycosylated hemoglobin levels in patients accepted LSG showed a downward trend. ConclusionsLSG on obesity with T2MD has an obvious short-term curative effect. But its long-term efficacy still needs to be supported by large samples randomized controlled clinical research data.
ObjectiveTo investigate the short-term effect of laparoscopic sleeve gastrectomy (LSG) in treatment of obesity in China. MethodsLiteratures about the effect of LSG in treatment of obesity were searched from WanFang, CNKI, PubMed, and Web of Science, then these literatures were filtered according to the inclusive and exclusive criteria and evaluated. Meta analysis was performed based on data extracted from these literatures. ResultsThree hundreds and eighty three cases of LSG were retrieved from 12 literatures. Compared with the preoperative, the body mass index (BMI) was lower in 6 months after LSG (MD=7.56, 95% CI: 5.77-9.34, P < 0.000 01), and compared with 6 months after LSG, the BMI was lower in 12 months after LSG (MD=3.19, 95% CI: 2.20-4.18, P < 0.000 01). Compared with 1 months after LSG, the excess weight loss (EWL%) was higher in 6 months after LSG (MD=-42.77, 95% CI:-45.77--39.77, P < 0.000 01), and compared with 6 months after LSG, EWL% was higher in 12 months after LSG (MD=-19.71, 95% CI:-25.54--13.87, P < 0.000 01). After the LSG, BMI decreased, but EWL% increased over time. ConclusionsIn China, LSG has obviously short-term curative effect in the treatment of obesity.
