目的探讨纤支镜在不明原因肺不张中的应用价值。方法50例X线诊断为肺不张患者同时进行胸部CT和纤支镜检查。结果两上叶肺不张肺癌比例最高,占59·3%(16/27);右中叶不张炎性反应比率最高,占66·7%(8/12)。其他部位均以肺癌为主要原因。纤支镜对肺不张病因诊断达98%(49/50),而胸部CT对肺不张病因诊断为78%(39/50)。两者比较差异有统计学意义P<0·05。结论在阻塞性肺不张的病因诊断方面,纤支镜检查明显优于胸部CT,纤支镜应作为不明原因肺不张的常规检查。
Objective To investigate the value of bronchofibroscopy in unexplained atelectasis. Methods 50 cases of X-ray diagnosis of atelectasis in patients with chest CT and bronchoscopy. Results The proportion of lung atelectasis in the two upper lobes was the highest, accounting for 59.3% (16/27). The ratio of atelectasis in right middle lobe was the highest, accounting for 66.7% (8/12). Other parts are lung cancer as the main reason. Fiberoptic bronchoscopy atelectasis of the cause of diagnosis of 98% (49/50), while the chest CT of the cause of atelectasis diagnosis of 78% (39/50). The difference between the two was statistically significant P <0 · 05. Conclusion In the diagnosis of obstructive pulmonary atelectasis, bronchoscopy is superior to chest CT, and bronchofibroscopy should be used as routine examination for unexplained atelectasis.
