自制穿刺活检固定仪在CT引导下经皮肺占位穿刺活检中的临床应用

目的探讨自制穿刺活检固定仪在CT引导下经皮肺占位穿刺活检中的临床价值。方法选取2008年11月～2013年4月我院收治的肺内占位性病变行穿刺活检的患者216例，回顾性研究穿刺活检的成功率、并发症及其影响因素。结果216例患者中，恶性病变188例，良性病变23例，穿刺活检成功率97．69％。病灶良恶性及病灶大小对穿刺活检成功率有显著影响（P〈0．05）。并发出血24例（11．1％），气胸27例（12．5％），气胸发生率与病灶大小及病灶距胸膜距离显著相关（P〈0．05）。结论自制穿刺活检固定仪的应用能够提高肺穿刺活检的成功率。

Clinical Appliction of Homemade Biopsy Locator in CT-Guided Percutaneous Puncture Biopsy of Lung Space-Occupying Lesions

Objective To explore the clinical value of the homemade biopsy locator in CT-guided percutaneous puncture biopsy of lung space-occupying lesions. Methods A retrospective study of 216 patients with lung space-occupying lesions who had been admitted from November 2008 to April 2013 in our hospital and underwent CT-guided percutaneous puncture biopsy was conducted to investigate the success rate and complications with their influence factors of percutaneous puncture biopsy. Results There were 188 cases with malignant lesions and 23 cases with benign lesions among all the patients （216 cases）. The success rate of percutaneous puncture biopsy was 97.69%. The natures of lesions including benign and malignant and the sizes of lesions can significantly affect the success rate of percutaneous puncture biopsy （P〈0.05）. The major complications ofpercutaneous puncture biopsy were hemorrhage （24 cases, 11.1%） and pneumothorax （27 cases, 12.5%）. The sizes and the depths of lesions can significantly affect the occurrence rate of pneumothorax （P〈0.05）. Conclusion The success rate of percutaneous puncture biopsy of lung space-occupying lesions can be improved with the application of the homemade biopsy locator.
