Radiofrequency thermal ablation (RFA) of liver tumors: open surgical or percutaneous approach?

RFA was used to ablate 81 liver lesions: 61 liver metastases and 20 hepatomas. An open surgical approach was adopted in 19 instances (27.5%), 12 of which were simultaneously treated for associated diseases, and percutaneous treatment was adopted in 50 instances (72.5%). The CT liver control at 6 months showed a complete necrosis in 50 lesions (66.3%). The advantages of the percutaneous approach include less invasiveness, reduced postoperative pain, shorter hospitalization, reduced costs and less discomfort in repeating the procedure. In conclusion, radiofrequency liver nodule ablation could be considered, today, as one of the promising and versatile techniques for loco-regional liver cancer control.
