Comparison between laparoscopic sleeve gastrectomy and laparoscopic adjustable gastric banding for morbid obesity / 国际外科学杂志

ABSTRACT

Objective To compare the effects of laparoscopic sleeve gastrectomy (LSG) and laparoscopic adjustable gastric banding (LAGB) on excess weight loss (EWL) and type 2 diabetes mellitus (T2DM),then to evaluate which one is superior to the other.Methods PubMed,Embase,Wanfang Database and HowNet database were searched for publications concerning LAGB and LSG from 2000 to 2012,with the last search on August 17,2012.EWL and T2DM improvement over 6 and 12 months were pooled and compared by meta-analysis.Odds ratios (ORs) and mean differences were calculated with 95％ confidence intervals （ CI).Results Eleven studies involving 1004 patients in total met the inclusion criteria.The mean percentage EWL for LAGB was 33.9％ after 6 months in studies and 37.8％ after 12 months; for LSG,EWL was 50.6％ after 6 months and 51.8％ after 12 months,T2DM was improved in 42 of 68 patients (61.8％) after LAGB and 66 of 80 (82.5％) after LSG.Conclusions LSG is more effective than LAGB in morbid obesity,with higher percentage EWL and greater improvement in T2DM.
