Summary

To evaluate local tumor progression rate at 12 months after no-touch percutaneous radiofrequency ablation using combined energy delivery mode and triple cooled electrodes

Conditions

• Recurrent Hepatocellular Cancer
• Chronic Liver Disease and Cirrhosis

Interventions

Type	Name	Description
PROCEDURE	Radiofrequency ablation using combined bipolar and monopolar energy deliver with Triple Cooled-Wet electrodes	Radiofrequency ablation will be performed by using triple cooled-wet electrodes. Two or three electrodes will be places around the tumor under ultrasonography (US)-computed tomography (CT)/magnetic resonance (MR) fusion tool guidance. The electrodes will be cooled with saline, and radiofrequency (RF, bipolar mode and switching monopolar mode) will be applied to two of three electrodes at the same time for about 6 to 30 minutes depending on the tumor size. The temperature will be maintained at 90-100 °C.
