Application value of CT-guided percutaneous puncture biopsy with coaxial localization needle in deep lung lesions

目的探讨同轴定位针CT引导下经皮穿刺活检在肺深部病变中的应用价值。方法选取行经皮穿刺活检的60例肺深部病变患者作为研究对象,根据是否采用同轴定位针引导分为2组。观察组33例患者采用同轴定位针CT引导下经皮穿刺活检,对照组27例患者采用常规CT定位经皮穿刺活检。观察并比较2组穿刺时间、平均穿刺次数、一次取材成功率、病变检出率、诊断准确率、并发症发生率。结果观察组穿刺时间短于对照组,一次取材成功率高于对照组,穿刺失败率低于对照组,差异均有统计学意义(P<0.05);2组诊断肺深部病变准确率比较,差异无统计学意义(P>0.05),观察组检测结果与手术或随访结果一致性较高(Kappa=0.725),对照组一致性中等(Kappa=0.631);观察组并发症发生率低于对照组,差异有统计学意义(P<0.05)。结论同轴定位针CT引导下经皮穿刺活检可提高穿刺成功率,降低穿刺相关并发症发生风险,与手术或随访结果一致性较高。

Objective To investigate the application value of CT-guided percutaneous needle biopsy with coaxial localization needle in deep lung lesions.Methods A total of 60 patients with deep pulmonary lesions undergoing percutaneous puncture biopsy with coaxial localization needle were selected and divided into two groups according to application of CT-guided coaxial localization needle.The observation group(n=33)underwent CT-guided percutaneous needle biopsy with coaxial localization needle,while the control group(n=27)underwent CT-guided percutaneous needle biopsy with conventional localization needle.The puncture time,the average puncture times,the success rate of one-time sampling,the detection rate of pathological changes,the accuracy rate of diagnosis and the incidence rate of complications were observed and compared between the two groups.Results The puncture time of the observation group was significantly shorter than that of the control group,the success rate of one-time sampling was significantly higher than that of the control group,and the failure rate of puncture was significantly lower than that of the control group(P<0.05).There was no significant difference in diagnostic accuracy of deep lung lesions between the two groups(P>0.05).In the observation group,the detection result was highly consistent with the results of operation and follow-up(Kappa=0.725),and had medium consistent results in the control group(Kappa=0.631).The incidence of complications in the observation group was significantly lower than that in the control group(P<0.05).Conclusion CT-guided percutaneous needle biopsy with coaxial localization needle can increase the success rate of puncture and reduce the risk of puncture-related complications,which is highly consistent with the results of surgery or follow-up.
