Recently percutaneous ethanol injection (PEI) turned into percutaneous radiofrequency ablation (PRFA), and it has become widely used for the treatment of hepatocellular carcinoma (HCC). The present study was to compare the incidence in postoperative HCC recurrence between these two therapeutic approaches. ⋯ The present study demonstrated that PRFA resulted in a lower rate of local recurrence in comparison to conventional PEI, regardless of the operator's experience.
