RFA for Small HCC With No-touch Technique and Dual Cooled-Wet Electrode

Radiofrequency Ablation Using Dual Cooled-Wet Electrode for Small Hepatocellular Carcinoma With No-touch Technique: Preliminary Study

The purpose of this study is to prospectively compare the clinical outcomes (local tumor progression rate, technical success rate, complication rate) of no touch radiofrequency ablation (RFA) technique for Hepatocellular carcinoma (HCC) to those of conventional tumor puncture RFA technique.

Inclusion Criteria:

• Child-Pugh class A
• patient with 1-2.5cm sized HCC
• 1 or 2 HCC lesions

Exclusion Criteria:

• maximum tumor diameter greater than 2.5cm
• Child-Pugh class B or C
• more than 3 HCC lesions
• invisible tumor even after US/CT or US/MR fusion
• presence of vascular tumor thrombosis or extrahepatic metastasis
• severe coagulopathy (PLT < 50K, PT < 50% of normal range)
