Improvement and development in anatomical hepatectomy for hepatocellular carcinoma

Liver resection is one of the best practical curative options for hepatocellular carcinoma(HCC).Since HCC spreads via portal venous system(1,2)and develops intrahepatic metastases,resecting tumor-bearing territory,so-called anatomical resection,is proven to provide higher curability than non-anatomical limited liver resection(3).
