纤支镜检查对支气管内膜结核和不排菌活动性肺结核都具有重要诊断价值。纤支镜检查可了解支气管病变的有无,以确定手术切除部位和防止术后支气管胸膜瘘、支气管播散及脓胸的发生。一、据统计,约有10～20%的活动性肺结核患者合并支气管内膜结核,而应用硬质支气管镜检查的阳性率不高,这是由于其可见范围较小,视野不够清晰,早期粘膜下病变很难发现之故。纤支镜对支气管内膜结核的诊断率明显提高,所见有三种类型:(1)浸润溃疡型,多发生于急性期,主要表现为
Bronchoscopy bronchial endometrial tuberculosis and non-polluting active tuberculosis have important diagnostic value. Bronchoscopy can understand the presence of bronchial lesions to determine the surgical site and to prevent postoperative bronchopleural fistula, bronchial disseminated and empyema occurred. According to statistics, about 10 to 20% of patients with active pulmonary tuberculosis complicated by endobronchial tuberculosis, and the application of rigid bronchoscopy positive rate is not high, which is due to its smaller visible range, the vision is not clear enough, early mucosa Under the disease is difficult to find out why. Bronchoscopy bronchial endometrial tuberculosis diagnosis rate was significantly improved, there are three types of see: (1) infiltrative ulcer type, occurred in the acute phase, mainly as
