Laparoscopic radiofrequency ablation for hepatocellular carcinoma.

Radiofrequency ablation (RFA) is one of the best curative treatments for hepatocellular carcinoma in selected patients, and this procedure can be applied either percutaneously or laparoscopically. Although the percutaneous approach is less invasive and is considered the first choice, RFA with laparoscopic guidance is highly recommended for patients with a relative contraindication for percutaneous RFA, such as lesions adjacent to the gastrointestinal tract, gallbladder, bile duct and heart. Recent advances in laparoscopic ultrasound have widened the indication for laparoscopic ablation. In the present paper, we review the indications, advantages, prognosis and safety of laparoscopic RFA for hepatocellular carcinoma.
