Conditions

Chronic Liver Disease and Cirrhosis, Recurrent Hepatocellular Cancer

Keywords

No-touch radiofrequency ablation, Combined energy delivery mode, Triple cooled-wet electrodes

Brief 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

Interventions

PROCEDURERadiofrequency 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.
