ABSTRACT
Benign occupations of the liver (BOL) are a heterogeneous group of benign hepatic lesions,a minority of which may need active management.It's reported that radiofrequency ablation (RFA) can be used to treat BOL,such as hepatic haemangioma,focal nodular hyperplasia (FNH),hepatocellular adenoma,simple hepatic cyst,liver abscess and hepatic echinococcosis.RFA has exhibited a potentiality to replace resection as the first-line treatment option for hepatic haemangioma.For multiloculated intractable simple hepatic cyst or liver abscess,when patients are not suitable for or refuse surgical resection,RFA may be an alternative option for the resection;and it also has many advantages over resection,including effectiveness,safety,minimal invasiveness and repeatability in the treatment of FNH,hepatocellular adenoma,and hepatic echinococcosis.A review will be presented on the current situation and latest progression of RFA therapy for BOL in this article.
