Answer

Radiofrequency ablation (RFA) uses probes that heat liver tumors and the surrounding margin of tissue to create coagulation necrosis. RFA can be performed percutaneously, laparoscopically, or through an open approach. Although RFA has minimal morbidity, local recurrence is a significant problem and correlates with tumor size.
