Abstract

BACKGROUND/AIMS: To determine the complication rate of multiple-electrode radiofrequency treatment of liver tumors, and their prevention and cure. METHODS: 114 patients with liver tumors were treated 170 times using multiple-electrode radiofrequency. The clinical complications and their prevention and cure were observed. RESULTS: The complication rate was 9.6%. The complications included 1 case of colon perforation, 4 cases of skin burn, 5 cases of hydrothorax, and 1 case subcutaneous hemorrhage, but none of the patient died due to these complications. CONCLUSION: The complication rate of multiple-electrode radiofrequency treatment of liver tumors is low and the complications could be prevented and cured.
