Cryosurgery for liver tumour is the therapy initially applied clinically in the authors' department. In Japan this therapy is hardly used in comparison with Europe and America. The authors have acquired experience of 68 patients with liver tumours treated using cryosurgery, and 15 were performed using the percutaneous transhepatic approach. Cumulative survival rate of their 30 patients with hepatic metastases from colorectal cancer were 59% in 1 year, 17% in 5 years. In the report of foreign facilities which have experienced a large number of patients, the cumulative survival rate of unresectable liver malignancy were about 60% in 2 years, about 20% in 5 years. Compared with other ablative therapy, cryosurgery has a strongly destructive force and damage of the blood vessel is infrequently observed. In this article, the technique, complications, clinical results, difference compared with ablations, and the further prospects of liver cryosurgery are outlined.
