Abstract

背景与目的肺小结节尤其是磨玻璃结节(ground glass opacity, GGO)病灶的定位是微创手术切除的难点,报道的方法很多但均有不足。本研究旨在探讨计算机断层扫描(computed tomography, CT)引导下Hook-wire术前定位在胸腔镜下(video-assisted thoracoscopic surgery, VATS)肺结节切除术中的临床应用价值,并初步探讨GGOs积极微创手术治疗的必要性和可行性。方法2013年5月-2015年6月共25例患者的26枚肺结节于术前行CT引导下Hook-wire定位,然后施行胸腔镜楔形切除术。统计Hook-wire定位时间、成功率、并发症及楔形切除时间、住院时间等,计算病灶组织学分型中的恶性几率,讨论肺部GGOs积极手术治疗的必要性。结果共25例患者26个结节(男性10例,女性15例,6个实性结节,20个GGOs),病灶直径5 mm-20 mm(平均8 mm),病灶距离胸膜垂直距离5 mm-30 mm(平均14 mm),CT引导下Hook-wire定位成功率为100%。VATS楔形切除术成功率为100%。CT定位时间平均10 min(5 min-15 min),微创切除病灶所需时间平均20 min(15 min-40 min),平均住院时间为4 d(3 d-6 d)。4例患者定位后发生微量气胸,但无需闭式引流处理。术中定位针脱落1例,但仍于胸腔镜下观察到穿刺点脏层胸膜下血肿后,准确定位并成功切除。20个GGOs术后组织学诊断结果为:16个混合性GGOs(mixed GGO, mGGO)中,微浸润腺癌2例,腺癌5例,小细胞肺癌(small cell lung cancer, SCLC)1例,炎性病灶8例;4个纯GGOs(pure GGO, pGGO)中原位腺癌1例,非典型性腺瘤样增生(atypical adenomatoid hyperplasia, AAH)1例,炎性病灶2例。结论CT引导下Hook-wire肺结节尤其是GGOs术前定位准确率高,相关并发症轻微,是一种安全、有效的方法,能快速确定下一步诊疗方案,值得临床推广;肺部mGGOs是恶性病灶的几率很大,积极微创手术治疗是非常必要的。
