CT引导下经皮肺穿刺活检在诊断肺占位性病变中的应用价值

目的:探讨CT引导下经皮肺穿刺活检在诊断肺占位性病变中的应用价值。方法:选取110例肺部不同占位性病变患者,回顾分析110例穿刺病理诊断结果,且记录术后是否出现不良反应及术后并发症,分析总结CT引导下经皮肺穿刺活检优缺点。结果:110例肺部不同占位性病变患者,均穿刺获得满意标本,一次性成功。肺穿刺组织经病理组织学检查后可确诊为肺癌患者83例,准确度(即一致性)93.6%(103/110),特异度74.1%(20/27),误诊率(假阳性率)25.9%(7/27),无假阴性,灵敏度100.0%(83/83)。110例肺穿刺活检后并发症发生率为27.3%,其中气胸严重者3例,占2.7%。结论:对肺部不同占位性病变患者进行CT引导下经皮肺穿刺活检的可行性及安全性均较高,无不良反应,值得临床上进一步推广应用。

The application value of percutaneous lung biopsy guided by CT in the diagnosis of pulmonary occupying lesions

Objective:To explore the application value of the percutaneous lung biopsy guided by CT in the diagnosis of pulmonary occupying lesions. Methods:The pathological data of different space. occupying lesions of lung in 110 patients were retrospectively analyzed. The postoperative adverse reactions and complications were recorded. The advantages and disadvantages of the percutaneous lung biopsy guided by CT technology were analyzed. Results:The effective specimens were successfully obtained from 110 patients with different space-occupying lesions,one-time. Eighty-three cases were identified by histologic examination,The diagnosis rate,specificity, false positive rate,false negative rate and sensibility were 93. 6%(103/110),74. 1%(20/27),25. 9%(7/27),0. 0% and 100. 0%(83/83),respectively. The incidence of complications caused by lung puncture biopsy in 110 cases was 27. 3%,serious pneumothorax in 3 cases ( accounting for 2. 7%) were found. Conclusions:The percutaneous lung biopsy guided by CT in patients with different pulmonary occupying lesions is feasible,safe and no adverse reaction,which is worthy of further clinical application.
