The radiology department of PUMCH, in cooperation with the department of anesthesia and the department of liver surgery, treated liver cancer with CT-guided radiofrequency ablation through percutaneous puncture under general anesthesia as from January 2009, and performed more than 400 surgeries in the past five years. The operations, being painless, turned out more humanistic.
The surgery is minimal invasive, safe and efficient. 95% patients can be discharged within 24 hours, thus much safer. Follow-up visits showed that 100% of tumors with a diameter of less than 5cm were inactivated after 1-3 times of radiofrequency ablation; for 18 cases of small hepatocellular carcinoma, follow-up visits between 3-59 months showed no death and no anesthesia-related complications. Radiofrequency ablation was reported successful on 58 cases with the tumor dangerously located under diaphragm, Glisson's capsule, beside great vessels, gallbladder or intestinal canal, under cardiac vesicle or beside spleen or stomach. It is generally believed in papers that the rates of radiofrequency ablation complications are 3%-9%, and the death rate is 1%, but PUMCH reported a rate of complications as low as 2.2%.
