Abstract:
OBJECTIVETo investigate the efficacy, indication and complication of radiofrequency ablation (RFA) with cool-tip needle in patients with hepatic malignancies.
METHODS421 patients with hepatic malignancies underwent ultrasound-guided RFA with cool-tip needle under local anaesthesia. The tumor size was from 1.0 to 15 cm in diameter with an average diameter of 4.3 cm.
RESULTSThe complete ablation (CA) rate was 91.4% (382/418) in the patients with a tumor < 3 cm, 78.9% (97/123) in those with a tumor of 3 to 5 cm and 37.6% (35/93) in the patients with a tumor > 5 cm. No patient died or changed to celiotomy during the 1121 times of RFA for 634 lesions in 421 patients. No hemorrhage occurred in any of these patients after the RFA treatment. The complications included abdominal pain in 32.3% (136/421), nausea in 9.0% (38/421), fever in 34.9% (147/421) and biliary leakage in 0.2% (1/421) of the patients.
CONCLUSIONUltrasound-guided percutaneous radiofrequency ablation with cool-tip needle is effective and safe in the treatment of liver tumors.
