Summary

This study is to investigate the therapeutic effect and treatment results of radiofrequency ablation using the Octopus MP electrode capable of temperature monitoring and drug injection and a variable-length electrode for treatment of small hepatocellular carcinomas (≤ 3cm).

Conditions

• Hepatocellular Carcinoma

Interventions

Type	Name	Description
PROCEDURE	Radiofrequency ablation	Radiofrequency ablation will be performed by using the Octopus MP electrodes. It is a method of directly measuring the temperature near the surrounding tissue of the target tumor using the Octopus MP electrode, and stopping ablation when the temperature rises above 60 degrees to prevent adjacent organ (gallbladder, gastrointestinal tracts, diaphragm, and heart). If the shape of the tumor is elliptical or irregular rather than circular, using an adjustable tip that can change the length of the active tip of the electrode according to the size of the tumor has the advantage of tailoring the ablation zone.
