肺结节术中体表定位在胸腔镜手术中的应用研究

背景与目的：关于肺结节手术的定位,目前报道较多的是在CT引导下的术前定位。我们通过研究,探讨一种更简便、安全、可靠的肺结节定位法,为需行胸腔镜下肺部分切除的肺结节患者提供精确的定位。方法：56例肺小结节患者通过术前CT上测量肺小结节在胸壁体表可以定位的位置,进而行胸腔镜下肺部分切除。术中麻醉成功摆置体位后,作好标记,消毒、铺巾后,于术前定位点用静脉套管针刺入,嘱麻醉师膨肺,用电凝烧灼套管针金属内芯外端,使肺表面留下电灼定位点,胸腔镜下根据电凝烧灼点,确定结节的位置。统计定位准确率、并发症发生率。结果：统计该胸壁体表定位法肺小结节定位点与结节的距离,结果准确定位的成功率为94.6%。其中3例患者术中发现小结节与定位点出现较大偏差(大于1.5 cm),有2例出现穿刺点活动性出血(发生率为3.6%),无其他并发症。结论：术中即时的肺结节体表定位法,区别于其他术前定位方法(如Hook-wire),该方法可以避免患者长时间暴露在放射线的辐射中,并减少患者疼痛及心理负担,减少术前定位环节。术中即时操作,并可避免其他有创定位法的各种并发症。是一种简便、安全、经济、精准的胸腔镜肺结节术前定位的好方法。

定位技术在电视胸腔镜诊治孤立性肺小结节中的应用

背景与目的电视胸腔镜已广泛应用于孤立性肺小结节(solitary pulmonary nodule,SPN)的诊治,但经常遇到术中无法准确定位病灶的情况。本研究探讨电视胸腔镜手术(video-assistant thoracoscopic surgery,VATS)在诊治孤立性肺小结节过程中的定位技术的临床应用价值。方法对孤立性肺小结节患者,术前先行三维CT定位,如SPN≤1.5 cm,或深达肺胸膜下2.0 cm,予行Hook-wire定位,术中先用器械间接触诊法,如失败改行电视胸腔镜辅助小切口(video-assisted minithoracotomy,VAMS),用手指直接触诊法定位,术中定位成功后,以直线切割缝合器行SPN楔形切除术,术后快速冰冻病理检查以决定下一步治疗方案。结果本组23例完成了胸腔镜SPN的切除,其中完全胸腔镜手术10例,VAMS 13例。结论电视胸腔镜SPN切除术术前术中的精确定位具有临床应用价值。

CT引导下带钩钢丝术前定位在胸腔镜下孤立性肺小结节切除术中的应用

Objective Video-assisted thoracoscopic surgery (VATS) provides a minimally invasive approach to resect small solitary pulmonary nodules (SSPN). The aim of this study is to evaluate the efficacy and safety of preoperative CT-guided hookwire localization for SSPN in VATS. Methods Hookwire was used to localize 26 SSPN under CT guidance in 24 patients (14 male, 10 female, age range 21-61 years, mean 52.3 years), preoperatively, and wedge resection was performed through VATS. The lesion size, distance from the lesion to parietal pleura, the time of localization and complications were evaluated. Results All the 26 pulmonary nodules were preoperatively detected and localized with hookwire under CT-guidance. The mean lesion size was 10.05 ± 3.08 nun in diameter, and the mean distance from lesion to parietal pleura was 10.09±2. 62 mm. The mean localization time was 20. 18±7.16 min, and then the nodules were removed by VATS within 18 ± 6. 65 min. The major complication of CT-guided hookwire localization was mild pneumothorax in 6 patients (25.0%), but no one needed chest tube drainage. The dislodgment of hookwire was found in only one patient (4.2%) during the operation, but the lesion was still successfully resected under VATS. Of those patients, 8 were confirmed to have a primary NSCLC by rapid pathologic diagnosis during VATS wedge resection, and then VATS lobectomies were performed. Condusion The preoperative CT-guided hookwire localization for small solitary pulmonary nodules is an effective and safe technique to assist VATS resection of the nodules.
