目的 探讨经皮穿刺深度冷冻治疗原发性肝癌的方法,安全性及临床应用的初步经验。方法 11例原发性肝癌患者,超声引导下穿刺至肝内肿瘤表面,LCS—2000冷冻机5mm冷冻头插至肿瘤中心冷冻。结果 11例病人冷冻治疗后恢复均顺利,无手术死亡及肝破裂、出血、胆瘘、穿刺窦道种植转移等并发症,穿刺部位愈合良好,5例肿瘤缩小≥50％,1例肿瘤完全消 失。结论 超声引导下经皮冷冻治疗肝癌是一种安全、有效、微创的治疗新方法。
Objective To explore the method, safety and preliminary experience of clinical application of deep cryotherapy for primary liver cancer. Methods 11 patients with primary liver cancer underwent ultrasound-guided puncture to the surface of intrahepatic tumors. The LCS-2000 freezer 5mm frozen head was inserted into the center of the tumor to be frozen. Results All 11 patients recovered well after cryotherapy. There were no complications such as operative death and hepatic rupture, hemorrhage, biliary fistula, puncture and sinus implantation. The puncture site healed well. In 5 patients, tumor shrinkage was ≥50%, and 1 tumor completely disappeared. . Conclusion Ultrasound-guided percutaneous cryotherapy for liver cancer is a safe, effective and minimally invasive treatment.
