利用支气管镜作为诊断肺癌的工具历史较久。硬式支气管镜检查对病人痛苦较大,且诊断阳性率较低。1967年开始,世界各国相继应用光导纤维支气管镜(以下简称纤镜)代替硬式支气管镜对支气管、肺疾病患者进行检查。由于痛苦较小,且检查范围较广,因此,病人易于接受,诊断阳性率亦较前大为提高。 The use of bronchoscopy as a tool for the diagnosis of lung cancer has a long history. Hard bronchoscopy is more painful to the patient, and the diagnostic positive rate is lower. Since 1967, all countries in the world have applied fiberoptic bronchoscopes (hereinafter referred to as fiberscopes) instead of rigid bronchoscopes to examine bronchial and pulmonary diseases. Since the pain is small and the scope of the examination is wide, the patient is easy to accept, and the positive rate of diagnosis is also much higher than before.
