[Objective] To study the atelectasis fiberoptic bronchoscopy to check the form and the value of the etiology and diagnosis. [Methods] 218 cases with imaging confirmed by bronchoscopy received atelectasis brush inspection, biopsy, bronchoalveolar lavage and other tests. [Results] A retrospective analysis on the etiology: 85 cases of malignant tumor (39.0%), 42 cases of inflammation (19.3%), 36 cases of embolus of sputum (16.5%), 32 cases of tuberculosis (14.7%), etc; the relationship between etiology and age: teens are not tumor's factors, main factors of middle-aged and old people are malignant tumor,iriflammation,embolus of sputum (total 80.6%) and other factors. [ Conclusion ] Fiberoptic bronchoscopy is of great value for the etiology and diagnosis of atelectasis, and the diagnosis rate is high (92.2%), safe and reliable.%目的 研究肺不张经纤维支气管镜(纤支镜)检查的形态和病因诊断的价值.方法 影像学确诊的218例肺不张患者经纤支镜刷检、活检、支气管肺泡灌洗术等检查.结果 就病因进行回顾性分析:恶性肿瘤85例(39.0％),炎症42例(19.3％),痰栓36例(16.5％),结核32例(14.7％)等;病因与年龄的关系:青少年人均为非肿瘤因素,中老年人以恶性肿瘤、炎症、痰栓(共80.6％)等因素为主.结论 纤支镜检查对肺不张的病因诊断有重要价值,其确诊率高(92.2％),安全可靠,且可进行相应治疗.
