摘　　要：目的 评价肺内结节性病灶胸腔镜术前CT引导下定位的可行性、安全性和临床价值.方法 68例行CT检查并接受胸腔镜切除术的患者,共74个难以定性的结节性病灶,术前皆行CT引导下Hook-wire定位.根据手术结果,评价术前CT引导下Hook-wire定位技术的失败率、并发症发生率、胸腔镜手术转为开胸手术的概率.结果 68例患者74个结节行胸腔镜切除术,术前CT引导下Hook-wire定位全部成功（100.0%）;无症状并发症发生率70.6%（48/68）,其中无症状气胸45.6%（31/68）、无症状出血25.0%（17/68）,同时发生气胸和出血者4.4%（3/68）;胸腔镜手术时间平均（15±6）min;中转开胸手术2例;住院时间平均为（15±6）d.肺内结节性病灶术后组织学诊断结果为：原发性肺癌30个,转移瘤18个,非恶性结节26个.结论 胸腔镜术前CT引导下Hook-wire定位结节病灶,中转开胸手术率低、安全快捷,对于肺内结节性病灶的定性诊断及制定治疗方案具有重要的指导意义.Objective To evaluate the feasibility,safety and clinical value of CT-guided localization with a Hook-wire system for nodular pulmonary lesions before video-assisted thoracoscopic resection （VATS）. Methods The records of all patients undergoing VATS resection for solitary pulmonary nodules preoperatively localized by CT-guided a Hook-wire system were assessed with respect to failure to localize the lesion by the Hook-wire system, conversion thoracotomy rate, duration of operation, postoperative complications, and histology of nodular pulmonary lesions. Results Sixty-eight patients with seventy four nodules underwent VATS resections. Preoperative CT-guided Hook-wire localization succeeded in all patients （ 100. 0% ）. Conversion thoracotomy was necessary in 2 patients. The average operative time was （ 15 ±6）min. Asymptomatic complication rate was 70.6% （48/68）, asymptomatic pneumothorax rate, asymptomatic hemorrhage rate and simultaneous pneumothorax and bleeding rate were 45.6% （31/68）,25.0% （ 17/68 ） and 4. 4% （ 3/68 ）, respectively. The mean hospitalization was （ 15 ± 6 ） days.Histological assessment revealed primary lung cancer （NSCLC） in 30, metastasis in 18, and nonmalignant disease in 26 nodules. Conclusions Video-assisted thoracoscopic resection of nodular pulmonary lesions previously localized by a CT-guided Hook-wire system is related to a low conversion thoracotomy rate, short operation time, and high safety. It for differential diagnosis and treatment.
