根据８年来经纤支镜检查确诊的１９６例肺癌纤支镜检查资料，结合文献资料，总结了肺癌纤支镜下的表现：镜下分型、各病理类型肺癌镜下表现的特点及镜下类型与常用纤支镜检查方法阳性率间的关系。指出为提高纤支镜检查方法阳性率，应注意结合使用直视下支气管粘膜活检、经支气管肺活检、经支气管壁针吸活检、刷检和支气管肺泡灌洗等取材方法，纤支镜检查不仅能为肺癌的确诊提供病理学依据，同时还能指导选择治疗方案，为中晚期中心型肺癌提供有效的特殊治疗手段。强调对疑诊肺癌患者进行纤支镜检查的重要性。
According to the data of bronchoscopy in 196 lung cancer patients diagnosed by fiberbronchoscopy over the past 8 years, combined with literature data, the performance of lung cancer under bronchoscopy was summarized: microscopic classification, characteristics of endoscopic appearance of lung cancer in each pathological type, and microscopic observation The relationship between the type and the positive rate of commonly used fiber bronchoscopy methods. It was pointed out that in order to increase the positive rate of bronchoscopy, attention should be paid to the combined methods of bronchial biopsy, transbronchial lung biopsy, transbronchial needle biopsy, brushing, and bronchoalveolar lavage under direct vision. Can provide pathological basis for the diagnosis of lung cancer, but also guide the choice of treatment options for the treatment of central and late-stage lung cancer to provide effective special treatment. Emphasis is placed on the importance of bronchoscopy in patients with suspected lung cancer.
