螺旋CT引导经皮肺穿刺术对周围性肺部病变的诊断意义

Diagnostic significance of spiral CT-guided percutaneous lung centesis on peripheral lung lesion

目的探讨螺旋CT引导经皮肺穿刺术对周围性肺部病变的诊断价值。方法 2011年12月-2015年12月在螺旋CT引导下行经皮肺穿刺活检的112例周围性肺部占位患者。所有患者均通过活检组织病理学和细胞学检查,比较两种方法所得阳性率是否有差异,同时分析诊断阳性率和并发症。结果 112例患者,穿刺全部成功。阳性结果为107例,阳性诊断率95.54%。有1例假阴性结果。不良反应(气胸和出血)发生率为8.92%。在针吸细胞学检测和活检病理检测相比较,在阳性率方面,其差异无统计学意义(P>0.05)。结论在诊断方面,螺旋CT引导下胸部穿刺术是安全、可靠的微创方法。

Objective To discuss the diagnostic significance of spiral CT-guided percutaneous lung puncture on peripheral lung lesion. Methods A retrospective study was conducted in 112 patients who underwent spiral CTguided percutaneous lung puncture on peripheral lung lesion from Dec,2011 to Dec,2015. Results The overall positive diagnostic rate was 95. 54%. The total complication incidence rate（ pneumothorax and bleeding） was8. 92%. There was no significant difference in positive diagnostic rate between needle aspiration cytology and needle biopsy（ P〉0. 05）. Conclusion The spiral CT-guided percutaneous lung centesis is a reliable and safe minimally invasive diagnostic technique on peripheral lung lesion.
