目的探讨纤维支气管镜在原因不明慢性咳嗽诊断中的价值。方法对咳嗽8周以上、X线胸片检查无异常的75例患者,排除嗜酸粒细胞性支气管炎、咳嗽变异性哮喘、胃食管反流综合征、变应性咳嗽和上气道咳嗽综合征后进行纤维支气管镜检查,以期明确咳嗽病因。结果支气管黏膜局限性充血、水肿22例(29.33%),气管或支气管结核8例(10.66%),支气管肺癌5例(6.66%),支气管异物2例(2.66%),声带结节1例(1.33%),支气管息肉1例(1.33%),局部管腔狭窄1例(1.33%),正常35例(46.66%),诊断阳性率为53.33%。结论纤维支气管镜检查对原因不明的慢性咳嗽有重要的诊断价值,值得临床推广。
Objective To investigate the value of fibrobronchoscopy in the diagnosis of chronic cough with unknown causes. Methods 75 patients with cough more than 8 weeks and no abnormal chest X-ray examination, excluding eosinophilic bronchitis, cough variant asthma, gastroesophageal reflux syndrome, allergic cough and upper airway cough syndrome Post-bronchoscopy, in order to clear the cause of cough. Results There were 22 cases (29.33%) with edema, 8 cases with tracheal or bronchial tuberculosis (10.66%), 5 cases with bronchogenic carcinoma (6.66%), 2 cases with bronchial foreign body (2.66%) and 1 case with vocal cord nodules 1.33%), bronchial polyps in 1 case (1.33%), local stenosis in 1 case (1.33%) and normal in 35 cases (46.66%). The diagnostic positive rate was 53.33%. Conclusions Fiberoptic bronchoscopy has important diagnostic value for chronic cough of unknown origin and is worthy of clinical promotion.
