Advantages of radiofrequency ablation treatment for liver tumors: The most important point is to minimize the invasiveness of liver tumor treatment, the electrode needle of radiofrequency only involves the maximum diameter of 5cm, which has little effect on the rest of liver tissues, especially for patients with severe cirrhosis, it is very important to preserve the functional liver tissues as much as possible. Therefore, it is more suitable for small hepatocellular carcinoma and multiple hepatocellular carcinomas, patients with severe cirrhosis who cannot tolerate surgical resection, and the patient’s reaction after treatment is small. Patients who are treated with extracorporeal or laparoscopic radiofrequency can be discharged from the hospital after 1-2 days of postoperative observation, and the patient suffers little pain and can return to normal life within a few days. Another advantage is that radiofrequency for liver tumor can be repeatedly performed, and the previous stage of radiofrequency has no effect on the later treatment, and the same is true for laparoscopic radiofrequency. This eliminates many people’s concern about re-operation. Disadvantages of radiofrequency ablation therapy for liver tumor: Any technology has certain limitations in clinical application. The most important thing for radiofrequency ablation therapy for liver tumor is the size of the tumor, the coverage of radiofrequency ablation for tumor larger than 5cm is not easy to complete, and the proportion of residual tumor is high. The first choice for such patients should be surgical resection, if they cannot tolerate surgery for physical reasons, they can be considered for liver tumor radiofrequency treatment. Another reason that affects the effect is the accuracy of RF electrode needle penetration. In theory, it is said that the electrode needle is distributed in each part of the tumor, but in practice, it is affected by various factors such as bad location, judgment of ultrasound image by severe cirrhotic nodules, equipment, etc., which directly affect the accuracy of penetration and finally have an effect on the effect.
