Radiofrequency ablation: a minimally invasive technique with multiple applications.

Abstract

RFA is a safe and effective alternative for the ablation of unresectable hepatic malignancies and when used adjunctively can reduce the morbidity of cryosurgery. Percutaneous and laparoscopic RFA can be performed effectively with less than 24 hours of hospitalization. Intraoperative ultrasonography is essential for accurate staging.
