目的 :探讨经皮肝穿刺集束电极射频治疗大肠癌肝转移的价值及其适应证。方法 :在 B超引导下 ,使用 RF2 0 0 0射频仪对 2 3例大肠癌肝转移患者 (共 39个转移结节 )进行集束电极射频治疗 ,比较治疗前后肝功能、血清 CEA、瘤体血供及大小的变化。结果 :术后 7d肝功能恢复至正常 ,78.3%患者血清 CEA术后 30 d内降至正常范围 ( P <0 .0 5 )。彩色 B超及 CT复查显示 :瘤体直径 <5 cm者 ,于术后 1～ 6个月内其瘤体血供消失、体积缩小甚至消失。瘤体直径≥ 5 cm者 ,于术后 1～6个月内瘤体血供消失、体积缩小。结论 :经皮肝穿刺集束电极射频治疗大肠癌肝转移疗效确切、简便安全
Objective : To explore the value and indications of radiofrequency ablation of colorectal carcinoma liver metastases with percutaneous transhepatic puncture electrode. METHODS: Radiofrequency ablation (RF) was performed on 23 patients with colorectal hepatic metastases (39 metastatic nodules) using radiofrequency (RF)-guided radiofrequency (RF-200) radiotherapy. Liver function, serum CEA, and tumor blood were compared before and after treatment. Supply and size change. Results: Liver function returned to normal 7 days after operation, and serum CEA decreased to normal range within 30 days after operation in 78.3% of patients (P < 0.05). Color B-ultrasound and CT examination showed that: tumor diameter <5 cm, within 1 to 6 months after surgery, the tumor blood supply disappeared, and the volume was reduced or even disappeared. The diameter of the tumor was ≥ 5 cm. The blood supply disappeared and the volume decreased within 1 to 6 months after operation. Conclusion : Therapeutic effect of percutaneous radiofrequency catheter ablation electrode for treatment of colorectal cancer liver metastases is clear, simple and safe
