Open surgery is a gold standard for treating hepatocellular carcinoma (HCC) and hepatic metastases of colorectal cancer. Today, liver resection is still only a radically option for patients with liver cancer, with a 5-year survival rate of 25-60%, compared with 0% 5-year survival without any treatment. Only 5-15% of patients with HCC or liver metastases may undergo hepatic resection due to different contraindications: a large number of tumors, tumors in hard-to-reach places, insufficient hepatic volume for resection.
