Prevention and cure of complications from multiple-electrode radiofrequency treatment of liver tumors.

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.

Main findings

In 114 patients treated 170 times with multiple-electrode radiofrequency for liver tumors, the reported complication rate was 9.6%. Reported complications were 1 colon perforation, 4 skin burns, 5 hydrothorax cases, and 1 subcutaneous hemorrhage; no deaths due to complications were reported.

Outcomes measured

• Clinical complications (overall complication rate)
• Colon perforation
• Skin burn
• Hydrothorax
• Subcutaneous hemorrhage
• Mortality due to complications

Limitations

• No details provided in abstract on study design features (e.g., randomization, control group).
• No exposure parameters (e.g., frequency, power, SAR) reported.
• Prevention/cure methods are mentioned but not described in the abstract.
