507例中叶和161例舌叶病变的纤维支气管镜检查和临床分析

目的　了解中叶和舌叶纤维支气管镜下病变的特点,为诊断提供依据。方法 对经纤维支气管镜检查的161例舌叶病变和507例中叶病变的临床症状、影像学及纤维支气管镜下异常表现进行回顾性分析。结果 中叶和舌叶纤维支气管镜下异常病变发生率之比3.1∶1,舌叶病变中肺癌居首位,胸片上具有团块影的肺癌征象仅占34.4%,纤维支气管镜检查示支气管壁异常改变和支气管腔内异常均以肺癌多见。中叶病变以肺炎多发,纤维支气管镜检查显示肺炎以支气管壁异常改变常见,肺癌以支气管腔内异常为主。结论 舌叶肺癌在胸片和纤维支气管镜下常见的典型表现不明显,纤维支气管镜检查对中、舌叶病变的早期诊断及鉴别诊断有着重要意义。

Retrospective analysis on the characteristics of lingular segments and right middle lobe lesions under broncho-scopic and clinical aspects

Objective To explore the characteristics of lesions in lingular bronchus and right middle lobe for providing diagnosis evidences.Methods Retrospective analysis on the clinical,radiological,and bronchoscopic characteristics of the 161 cases with lingular segments lesions and 507 cases with right middle lobe lesions from a total of 5?286 cases examined by fiberoptic bronchoscopy.Results The ratio of the incidence between right middle lobe and lingular segment lesions was 3.1∶1.Out of these cases lingular bronchus with lingular bronchus lesions,the number of lung carcinoma patient was the top one.The lump image with cancer symptom only constitutes 34.4% of all lung cancers.Abnormality in the bronchial wall and bronchial cavity found by the fiberoptic bronchoscopy commonly resulted by lung cancers.Pneumonia occured frequently at right middle lobe.Abnormality in its bronchial all was commonly resulted by pneumonia,and abnormorlity in its bronchial cavity was mostly observed in lung cancer by fiberoptic bronchoscopy.Conclusion The typical signs of lung cancer in lingular segments are undefined by the chest radiography and fiberoptic bronchoscopy.Fiberoptic bronchoscopy examination would play important role in early diagnosis and identification diagnosis for the lingular segments and middle lobe lesions.
