经支气管镜联合针吸嵌夹刷检在肺部肿瘤诊断中的价值

目的 探讨经支气管镜针吸(TBNA)细胞学检查及其与嵌夹、刷检在肺癌诊断中的应用价值.方法 胸部CT检查发现肺部病变需要经支气管镜检查确诊的101例患者,常规进镜,发现病变后依次针吸、嵌夹、刷检,进行病理和细胞学检查.结果 101例中最终确诊肺癌91例,其中支气管镜确诊86例,确诊率94.5%.针吸、嵌夹、刷检的阳性率为71.4%、75.8%、61.5%,单靠针吸获组织学诊断5例.结论 TBNA对各种病理类型和不同镜下表现的肺癌均有重要诊断价值,3种取材方法 联合使用能进一步提高诊断率.

The value about the combined application of transbronchiai needle aspiration and ring clamp biopsy, also brush biopsy through bronchofibroscope on the lung tumor

Objective To study the application value of cytological examination and biopsy for the transbronchial needle aspiration (TBNA) in the diagnosis of cancer. Methods 101 patients with lung disease by CT that need TBNA examination to make final diagnosis were selected. They were executed with routine ex-amination of TBNA. And then pathologic biopsy and cytological examination were applied on the collection sam-pies. Results 86 patients among the 96 subjects were finally diagnosed by TBNA. So the ratio of final diagno-sis was 94. 5%. And the positive ratios about transbronchial needle aspiration and ring clamp biopsy, also brush biopsy, were 71.4% 、75.8%、 61.5%. Only 5 patients were histodiagnosed by just transbrenchial needle aspiration. Conclusion TBNA plays an important role on the diagnosis of lung tumor with different types. And the combination of three methods can improve the diagnosis pro-gressively.
