目的探讨超声引导经皮射频消融(radiofrequenceablation.RFA)治疗毗邻横膈部肝癌的疗效与安全性。方法

对97例肝癌患者应用超声及CT将其分为毗邻横膈组肝癌(肿瘤距横膈≤5mm)A组46例;非毗邻横膈组肝癌(肿

瘤距横膈>5mm)B组51例,其中A组46个病灶,B组56个病灶,两组患者在超声引导下RFA治疗,肿瘤显示不清者建立

人工胸水。治疗结束后15min行即时超声造影<contrastenhancedultrasound。CEUS)或增强CT(contrast

enhancedCT。

CECT)检查。评估即时疗效,如有肿瘤残留,可追加治疗,l~6个月再行CEUS或CECT检查,评估近期疗效,后续每隔6

个月行CEUS或CECT检查,共随访5年,评估远期疗效。

结果RFA治疗毗邻横膈部肝癌无严重并发症发生。轻微并发症:A组误穿人胸腔1例,膈肌灼伤6例,超声及CT显示膈肌增强增厚。反应性胸腔积液1例;B组胆囊壁灼伤5例,肝被膜下血肿1例,两组并发症分别为17.4%、11.8%.差异无统计学意义(P=0.496)。膈肌及胆囊灼伤均为可逆性,无需处理,均在1个月内恢复正常。术后1个月A、B两组肿瘤完全灭活率为82.6%、83,9%(P一0.96);肿瘤残留分别为17.4%、16.1%(P=0.88);术后1年复发率8.7%、8.9%(P一0.97),差异均无统计学意义。

结论超声引导下应用单极冷循环系统多针多点重叠RFA治疗毗邻横部肝癌是一种安全有效的治疗方法。
