目的 分析孤立性肺部小结节（SPN）在电视胸腔镜（VATS）术前CT引导下定位的价值。方法 回顾性分析我院2013年6月～2016年6月收治的肺部小结节VATS手术的58例患者,其中,将VATS术前行CT引导下定位术31例设为观察组。另27例行单纯VATS术为对照组,分析比较两组手术时间、术后住院时间、出血量、疼痛情况以及术中转开胸手术情况。结果 观察组与对照组比较,两组病理结果比较差异无统计学意义（P〉0.05）,但手术时间、术后住院时间、出血量、疼痛及术中转开胸均低于对照组,两组比较差异有统计学意义（P〈0.05）。结论肺部小结节在胸腔镜术前先行CT引导下定位术具有确切临床手术增益价值。
Objective To investigate the value of preoperative CT-guided localization of VATS in the treatment of soli- tary pulmonary nodules（SPN）. Methods A total of 58 patients who were admitted to our hospital and were given VATS surgery of pulmonary nodules from June 2013 to June 2016 were retrospectively analyzed. Among them, 31 cases who were given CT-guided localization before VATS were enrolled in the observation group. The other 27 patients who were given simple VATS were enrolled in the control group. The operation time, postoperative hospital stay, bleeding volume, pain and switching to tboracotomy during the operation were analyzed and compared. Results The two groups were compared, and there was no significant difference in the pathological results between the two groups（P〉0.05）. However, the operation time, postoperative hospital stay, bleeding volume, pain and switching to thoracotomy during the operation in the observation group were lower than those in the control group. There were significant differences between the two groups （P〈0.05）. Conclusion CT-guided localization of small pulmonary nodules before thoracoscopic surgery has a definite clinical value of surgical operation.
