摘要 目的总结hookwire术前定位在全胸腔镜下切除肺部直径小于2cm的孤立性小结节的临床经验。方法回顾性分析2010年7月至2012年10月中山大学附属中山医院82例肺部孤立性小结节,共88个直径小于2cm的肺部孤立性病灶,行全胸腔镜下病灶切除术,术前均在数字减影(DSA)InnovaCT引导下采用hookwire对病灶穿刺定位的临床资料,其中男47例、女35例,年龄34~78(61.4±10.7)岁。对手指触诊阳性率与病灶临床因素进行相关性分析,比较手指触诊与hookwire定位的成功率,并总结hookwire定位的安全性、有效性及适应证。结果Hookwire定位常见并发症为无症状气胸13例(14.8%),少量血胸7例(7.9%),严重胸痛3例(3.4%)。9个病灶(10.2%)术中发现穿刺针移位。85个(96.5%)病灶可通过Hookwire准确定位,与触诊(53.4%)准确性差异无统计学意义(P=-0.097)。手指触诊的阳性率与病灶的病理类型和病灶的性质有关,对于微浸润性/浸润前病变、肺部单纯性磨玻璃样结节(pureground-glassopacity,pGGO)的触诊阳性率明显偏低,分别为25.8%和19.2%。结论对于直径小于2cm的肺部孤立性结节,胸腔镜手术前hookwire穿刺定位是一项安全的技术。其最佳适应证为直径小于2cm的pGGO。
