目的 :了解慢性咳嗽的病因及纤维支气管镜对慢性咳嗽的诊断价值。方法 :对我院 1 994年～ 2 0 0 1年行纤维支气管镜检查的 64例慢性咳嗽患者进行回顾性分析。结果 :在慢性咳嗽中 ,肺部慢性炎症仍占据首位 ,但随着年龄的增长 ,肺癌和结核引起的慢性咳嗽明显上升 ,纤维支气管镜检查可明显提高慢性咳嗽的病因诊断。结论 :在慢性咳嗽的鉴别诊断中 ,纤维支气管镜检查具有不可替代的作用 Objective: To understand the etiology of chronic cough and the value of bronchoscopy in the diagnosis of chronic cough. Methods: A retrospective analysis was performed on 64 chronic cough patients who underwent fibrobronchoscopy between 1994 and 2001 in our hospital. Results: In chronic cough, chronic lung inflammation still occupy the first place, but chronic cough caused by lung cancer and tuberculosis obviously increases with age. Fiberoptic bronchoscopy can obviously improve the etiological diagnosis of chronic cough. Conclusion: Fiberoptic bronchoscopy plays an irreplaceable role in the differential diagnosis of chronic cough
