Chronic Liver Disease and Cirrhosis, Recurrent Hepatocellular Cancer
Conditions
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
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.
