[Percutaneous radiofrequency coagulation therapy for liver tumor: experimental study].
We invented a newly devised local thermal therapy using radiofrequency energy for treating liver tumors. This method was investigated for evaluating its safety and effectiveness. In vitro study, the maximum size of coagulated albumen was 5.5 to 6.2mm in diameter, and 9.8 to 11.3mm in length. In vivo study using rabbit's liver, the range of coagulated tissue by radiofrequency energy was localized around the tip of the needle. Percutaneous radiofrequency coagulation therapy will be the effective therapy for liver tumor regardless of tumor vascularity.
