Radiofrequency ablation is a minimally invasive treatment to treat diseases by ablating abnormal lesions or hyperplastic tissues through the heat generated by radiofrequency current from the catheter under the guidance of ultrasound or CT. The advantages and disadvantages are as follows. 1. Advantages: Radiofrequency ablation is less invasive, with less bleeding during the operation, faster recovery after the operation, and can be repeated if necessary. 2. Disadvantages: Radiofrequency ablation has complications such as nerve damage, vasospasm, adhesion, infection, bleeding, etc.; due to the destruction of tissues, it may also affect the results of pathological examination; the coverage of radiofrequency ablation may be incomplete, so there is a possibility of postoperative recurrence. Radiofrequency ablation is performed under the guidance of ultrasound or CT, so there may be some deviation in treatment that may affect the results. Therefore, in case of disease, it is necessary to have a thorough evaluation by a doctor before undergoing RF ablation.
