摘要
目的:探讨胸腔镜手术前使用CT引导带钩钢丝定位,确定肺部小结节位置,以利于手术中切除的疗效与安全性。方法:收集自2012年2月至2014年3月天津医科大学肿瘤医院住院34例患者,术前使用CT引导下带钩钢丝(hookwire)定位肺部小结节,定位完成后直接行胸腔镜下肺部病变切除,根据术中冰冻病理结果决定下一步术式。结果:肺部小结节直径5~22 mm。采用CT引导下hookwire定位成功率100%,中位定位时间23 min。2例患者在操作过程中穿刺针脱落,有3例患者定位后CT扫描时发现气胸。结论:术前使用CT引导下带钩钢丝定位肺部微小病变的方法准确、安全性高,能够提高胸腔镜手术中肺部结节切除的准确率。
Objective:To explore the feasibility and safety of CT-guided hookwire localization of small lung nodule in video-as-sisted thoracic surgery. Methods: Preoperative localization of small lung nodule was performed using the CT-guided hookwire tech-nique, followed by video-assisted thoracic surgery in the wedge resection. The next mode of operation depends on the results of frozen biopsy. Results:Preoperative localization with CT-guided hookwire was performed in 34 patients between February 2012 and March 2014. The diameter of lung nodule ranged from 5 mm to 22 mm. CT-guided hookwire localization was successful in all patients, with a median positioning time of 23 min. Puncture needles were detached from two of the total patients during the surgery, and three other pa-tients showed pneumothorax by CT scan after localization. Conclusion:Preoperative hookwire localization of small lung nodule is an accurate and safe approach to improve the rate of wedge resection in video-assisted thoracic surgery.
