Liver ablation is a minimally invasive procedure to treat liver tumors in the following way: Prior to the procedure, the patient first completes a liver ultrasound to assess the safe path of the liver mass, and a routine sterilization is also done, followed by local anesthesia. Equipped with color ultrasound and cardiac monitoring, an ablation needle is used to puncture inside the mass, and then physical heating is utilized, which can inactivate the mass in situ, and this treatment method allows real-time monitoring of the procedure, and also timely assessment of the effect of ablation. Although radiofrequency ablation surgery for liver cancer is a minimally invasive surgery, there are certain postoperative complications, such as pain due to the high temperature of the ablation needle stimulating the peritoneum that can occur in some patients, or hematoma or bleeding at the puncture point of the liver. It is recommended to go to regular hospitals for systematic diagnosis and treatment when liver tumors are found.
