ABSTRACT
Objective To compare the results of the anterior approach (AA) with the conventional approach in the treatment of large hepatocellular carcinoma (HCC).Methods We searched the Medline,PubMed,Cochrane Library,Wanfang database on randomized clinical controlled trials and non-randomized clinical controlled trials comparing AA with the CA in right hepatic resection for large hepatocellular carcinoma.The data were analyzed with the RevMan5 software.Results Five non-randomized clinical controlled trials (NRCTs) and three randomized clinical controlled trials involving 615 patients (304 in the AA group,311 in the CA group) were enrolled into the analysis.There was no significant difference in the operation time between the two groups.Compared with the CA,the AA had lower intraoperative blood loss (WMD=-680.2 ml; 95％CI,-1023.97～-336.43;P=0.0001),blood transfusion rate (OR=0.38;95％ CI,0.25～0.59;P＜0.0001),intraoperative tumor rupture (OR=0.33;95％CI,0.11～0.97;P=0.04),surgical complication (OR=0.59;95％CI,0.38 ～ 0.93 ; P =0.02),hospital mortality (OR =0.37 ; 95 ％ CI,0.21 ～ 0.67 ; P =0.0009),and hospital stay (WMD=-4.75 d;95％CI,-7.82～-1.67;P=0.002).Conclusion AA is superior to CA in the treatment of larger.The operation time is the same for the 2 approaches.
