Radiofrequency Ablation of Abdominal Tumours

Alternative methods of tumour destruction have been sought for some time (alcohol, cryotherapy, laser photocoagulation), but more recently radiofrequency ablation (RFA) has caused particular interest due to its increasing efficacy and easeof-use. It has become an important tool in the treatment of hepatic metastases and primary hepatic malignancies, and there is a body of evidence developing that it is a safe and effective way of treating small renal malignancies. It can be administered percutaneously or perioperatively under image guidance and ultrasound is usually the modality of choice because of the advantage of real time imaging.
