Abstract:
Objective To systematically compare the clinical efficacy of hepatectomy via anterior approach and the conventional approach for the treatment of giant liver cancer.Methods The database including Cochrane library,PubMed,Web of Knowledge,EMBASE,China National Knowledge Infrastructure (CNKI),Chinese Medical Current Contents(CMCC),Wanfang database were searched with the key words of原发性肝癌,转移性肝癌,手术,肝切除术,前入路,绕肝提拉法,传统入路,hepatocellular carcinoma,metastatic liver cancer,HCC,surgery,liver resection,hepatectomy,hepatic resection,anterior approach,conventional approach and liver hanging maneuver between the database establishment and December 2013.Chinese and English literatures on major hepatectomy via anterior approach and conventional approach for the treatment of giant liver cancer were retrieved,and data were analyzed by 2 independent researchers.Meta analysis was carried out using the software of Review Manager 5.1.2.The count data were analyzed using the odds ratio (OR).The quantitative data were analyzed by the weighted mean difference (WMD),and were presented by 95％ confidence interval (95％ CI).Results Thirteen literatures with 1 287 giant liver cancer patients were retrieved,including 603 patients receiving hepatectomy via anterior approach and 684 via conventional approach.Three literatures were enrolled in the randomly controlled studies,one had high risk of bias and the other 2 had low risk of bias.Ten literatures were enrolled in the non-randomly controlled studies with the mean score of 7 (range,5-9).The results of Meta analysis showed that hepatectomy via anterior approach could reduce the volume of intraoperative blood loss (MD =-349.39,95％ CI:-636.90--61.81,P ＜ 0.05),the blood transmission rate (OR =0.41,95％ CI:0.24-0.72,P ＜ 0.05),the operation time (MD =-40.81,95 ％ CI:-57.81--23.80,P ＜ 0.05),the mean time of hospital stay (MD =-4.52,95 ％ CI:-8.36--0.69,P ＜ 0.05) and the postoperative mortality and incidence of postoperative complications (OR =0.32,0.68,95 ％ CI:0.16-0.62,0.53-0.88,P ＜ 0.05) when compared with the conventional approach,further more,hepatectomy via the anterior approach could reduce the postoperative recurrence of giant liver cancer and had higher overall 1-and 3-year survival rates (OR =0.45,2.72,4.47,95％ CI:0.29-0.69,1.59-4.66,2.61-7.63,P ＜ 0.05).Conclusion The safety of hepatectomy via anterior approach is similar to that of the conventional approach,while the short-and long-term efficacy are superior to those of the conventional approach.
