目的：探讨纤维支气管镜（纤支镜）检查对原因不明孤立性外周肺结节诊断价值。方法：对１０６例孤立性外周肺结节（ＳＰＮ）纤支镜检查结果进行回顾性分析。结果：３４％ＳＰＮ经纤支镜诊断为肺癌；ＳＰＮ经纤支镜肺癌诊断率随患者的年龄和病程增加而增加，有咯血症状者ＳＰＮ肺癌诊断率显著高于无咯血症状者。胸痛的有无、结节的大小及其在肺内的分布，对ＳＰＮ经纤支镜肺癌诊断率无明显影响。结论：纤支镜检查对ＳＰＮ的临床诊断及其分期具有较高价值
Objective: To investigate the diagnostic value of fiberoptic bronchoscopy (BFI) in the detection of peripheral pulmonary nodules of unknown origin. Methods: Retrospective analysis of the bronchoscopic findings of 106 patients with isolated peripheral pulmonary nodules (SPN). Results: 34% SPN was diagnosed as lung cancer by bronchoscopy. The diagnostic rate of SPN by bronchofibrosis was increased with the age and course of the disease. The diagnosis rate of SPN lung cancer with hemoptysis was significantly higher than that without hemoptysis. The presence or absence of chest pain, the size of the nodule, and its distribution in the lung have no significant effect on the diagnostic rate of SPN transbronchial lung cancer. Conclusion: Fiberoptic bronchoscopy is valuable for the clinical diagnosis and staging of SPN
