中央气道狭窄78例误诊分析

Central Airway Stenosis:An analysis of 78 cases with misdiagnosis

目的探讨中央气道狭窄的病因和误诊原因。方法回顾性分析初诊误诊的78例中央气道狭窄患者的临床资料。结果78例患者均经支气管镜检查确诊,良性狭窄32例,其中气管支气管结核24例;恶性狭窄46例,其中支气管肺癌40例。78例院外就诊均被误诊,其中误诊为支气管哮喘急性发作48例、慢性阻塞性肺疾病急性加重15例、自发性气胸10例、心源性哮喘5例。结论中央气道狭窄的临床表现无特异性容易被误诊,对可疑患者应及时进行支气管镜的检查以明确诊断。

Objective To investigate the etiological causes and the reasons ofmisdiagnosis of central airway stenosis. Methods The data of 78 central airway stenosis patients with misdiagnosis were retrospectively analyzed.Results All the 78 central airway stenosis patients were diagnosed by bronchoscopy, with 32 being benign cases including 24 cases of bronchial tuberculosis and 46 being malignant including 40 cases of primary lung cancer. All the 78 patients were misdiagnosed before they came to our hospital, including 48 with acute episode of bronchial asthma, 15 with acute episode of chronic obstructive pulmonary disease, 10 with spontaneous pneumothorax and 5 with cardiac asthma.Conclusion The clinical features of central airway stenosis are atypical and easy to be misdiagnosed. So for a suspicious patient of central airway stenosis bronchoscopy should be timely given for diagnosis.
