目的探讨超声引导射频消融术 (RFA)对肝癌、肝转移癌的疗效。方法对不能或不宜手术治疗的原发性肝癌 82例 ,肝转移癌 4 9例 ,共计 131例 ,2 2 6个癌灶 ,行超声引导下射频消融治疗。结果治疗后 1d～ 1个月CT检查 ,可见 2 0 3个癌灶被灭活 ,有效灭活率达 90 % (2 0 3/ 2 2 6个灶 ) ;另有 1例肝撕裂伤及 1例肝癌破裂出血者行RFA止血成功。 10 6例经 3～ 2 6个月随访 ,生存率 3个月或以上达 98 1% (10 4 / 10 6例 ) ,6个月或以上达 85 7% (72 / 84例 ) ,1年以上达 73 7% (42 / 5 7例 ) ,6例出现并发症 (4 6 % ) ,包括出血 ,脓肿 ,胆瘘 ,胆囊炎等。结论超声引导RFA具有疗效好 ,治疗周期短 ,患者创伤小 ,易接受 ,可反复治疗等优点。
Objective To investigate the curative effect of ultrasound-guided radiofrequency ablation (RFA) on liver cancer and liver metastases. Methods 82 cases of primary liver cancer, 49 cases of liver metastases, 131 cases in total, and 226 cases of cancer were treated with radiofrequency ablation guided by ultrasound. Results CT examination at 1 day to 1 month after treatment showed that 203 cancerous lesions were inactivated and the effective inactivation rate was 90% (203/226). Another case of liver laceration and One case of ruptured liver cancer patients underwent RFA hemostasis. 106 cases were followed up for 3 ~ 26 months, the survival rate was 981% (10 4/106) for three months or more, 85.7% (72/84) for 6 months or more, and one year More than 73.7% (42/57) patients had complications, and 6 patients had complications (46%), including hemorrhage, abscess, biliary fistula and cholecystitis. Conclusion Ultrasound-guided RFA has the advantages of good curative effect, short treatment period, small trauma, easy acceptance and repeated treatment.
