纤维支气管镜检查对右肺中叶不张的诊断价值的再评价

目的：进一步探讨右肺叶叶不张的原因及纤维支气管镜的诊断价值。方法：对２６２例对胸部Ｘ片或胸部ＣＴ诊断右肺叶叶不张的患者进行纤维支气管镜检查。结果：纤维支气管镜下发现新生肿物７５例（２８．６２％）,５２例（１９．８５％）可见管腔明显狭窄,非特异性改变占５３例（２０．２３％）,８２例（３１．２９％）镜下未见明显异常。经钎支镜确诊为肺癌７８例（２９．７７％）,４５岁以上鹗２６例占同年龄右肺中叶不张患者的

A STUDY ON RE-EVALUATING THE DIAGNOSTIC VALUE OF FIBROBRONCHOSCOPIC FINDINGS FOR RIGHT MIDDLE LOBE ATELECTASIS

Objective: To follow up the causes of right middle lobe atelectasis and the diagnostic value of bronchoscopic findings for this disease. Methods: 262 cases of right middle lobe atelectasis proved by chest radiography or computerized tomography (CT) were examined with bronchoscopy. Results: Specific endoscopic findings of neoplastic masses were seen in 75 cases (28.62%) and bronchial stenosis in 52 cases (19.85%). Abnormal but nonspecific changes were presented in 54 cases (20.23%) while normal endoscopic findings were presented in 82 cases (31.29%) of these patients. Chronic inflammatory disease was the most common etiological factor (56.49%). Tumors diagnosed by branchofiberoscope accounted for 29.77% (78/262). Conclusions: Benign inflammatory disease, tumors and tuberculosis are still the common causes of right middle lobe atelectasis. Tumors account for a high percent in the patients more than 45 years old. Bronchoscopy is vital in rational approach to right middle lobe atelectasis. The diagnostic value of Bronchoscopy for this disease appears to be almost 50%.
