目的:探讨支气管内膜结核(EBTB)的临床特征及早期诊断方法。方法:回顾性分析41例确诊的EBTB患者的临床资料。结果 :纤维支气管镜(FB)检查提示增殖型病变12.5%,溃疡型病变45%,炎症浸润型病变17.5%,狭窄闭塞型病变20%,大致正常5%。结论:EBTB缺乏特异性临床表现,联合PPD试验、痰TB-DNA在EBTB初筛可提高EBTB早期诊断率,确诊主要依靠FB检查,联合应用刷检、支气管肺泡灌洗及活检对于EBTB诊断起着关键性作用。 Objective: To investigate the clinical characteristics and early diagnosis of bronchial invagination (EBTB). Methods: The clinical data of 41 EBRB patients diagnosed were retrospectively analyzed. RESULTS: Fiberoptic bronchoscopy (FB) revealed a proliferative lesion of 12.5%, ulcerative lesions of 45%, inflammatory infiltrates of 17.5%, and stenotic occlusions of 20% and approximately normal 5%. Conclusion: EBTB lack of specific clinical manifestations, combined with PPD test, sputum TB-DNA in EBTB screening can improve the early diagnosis of EBTB, confirmed mainly rely on FB examination, joint application of brushing, bronchoalveolar lavage and biopsy for EBTB diagnosis plays The key role.
