经支气管镜肺活检及刷检在肺部占位性病变中的诊断价值

目的评价支气管镜肺活检（TBLB）及刷检（BB）对肺部占位性病变的诊断价值。方法回顾性分析121例胸部CT或X线检查发现肺部占位患者,经病理学、细胞学及临床最终诊断确诊肺癌83例,结核20例,非特异性炎症及其他疾病18例,对TBLB、BB结果分析,了解TBLB、BB病例取材方法的诊断阳性率。结果121例患者中采用TBLB、BB、TBLB＋BB对肺癌、肺结核的检出阳性例数和阳性率为肺癌：37例（44.6%）、16例（19.3%）、42例（50.6%）,肺结核：8例（40%）,4例（20%）,11例（55%）。结论经支气管镜肺活检及刷检对肺部占位性病变是安全、可靠、方便的诊断方法。

Value of transbronchial lung biopsy and brush biopsy in the diagnosis of pulmonary nodules

Objective To evaluate the diagnostic value of transbronchial lung biopsy（TBLB）and brush biopsy （BB）via fiberoptic bronchoscope for pulmonary nodules. Methods A total of 121 patients who presented with pulmonary nodules in chest radiography were proven with pulmonary carcinoma （ n = 83 ）, pulmonary tuberculosis （ n = 20 ）, and nonspecific inflammation or others （n = 18） according to the examination of cytology, histology, and clinical evidence. Each patient received TBLB and BB via fiberoptic bronchoscope without fluoroscopic guidance. The clinical data and pathologic diagnosis were analyzed. Restults The positive diagnosis rate of TBLB,BB and TBLB＋BB for pulmonary carcinoma was 44. 6% ,19. 3% and 50. 6% ,for pulmonary tuberculosis was 40% ,20% and 55% respectively. Conclusion TBLB and BB in diagnosis of pulmonary nodules is a safe,reliable and handy method.
