Abstract

Ablative therapies have recently emerged as an alternate to the gold-standard liver resection in treatment of malignant liver tumors. These modalities include radiofrequency ablation and microwave ablation which utilize thermocoagulative energy and microwave energy, respectively, to create a complete necrosis zone encircling the lesion. In this review, we aimed to show different perspectives of these treatment methods including indications, outcomes, surgical techniques, and perioperative management.
