Totally Laparoscopic Versus Laparoscopically Assisted Surgery For Distal Gastric Cancer: A Meta-analysis

Objective: To compare the safety、efficacy and minimally invasive betweentotally laparoscopic and laparoscopic-assisted for distal gastric cancer with Meta-analysis.Methods: Original articles addressing totally laparoscopic distal gastrectomyversus laparoscopy-assisted distal gastrectomy published from January2007toAugust2013were searched for in electronic databases(Pubmed、 Elsevier、SPRINGER、 The Cochrane Library).With strictly screening accordance to thestandard, assessing the quality of these studies, data were extracted from these trialsand analyzed by the Review Manager5.2software at last.Results: Five studies including849patients were selected for this study,Metaanalysis showed that： There was no obvious difference in the operationtime(WMD=8.16，95%CI:-12.31～28.63,P=0.43),Intraoperative blood loss in theTLDG group was less than LADG group （WMD=30.34，95%CI:16.54～44.13,P<0.0001）; lymph node cleane（rWMD=-2.46，95%CI:-4.61～-0.32,P=0.02），The postoperative complications was not increased in the TLDG group versus LADGgroup（OR=0.91，95%CI:0.58～1.42,P=0.67）.Conclusion: Totally laparoscopic distal gastrectomy is safe、 efficacy andminimally invasive.
