对36例患者采用经纤维支气管镜同时依次进行支气管冲洗液(BWF)检查、针吸活检(TBNA)、肺活检(TBLB)、毛刷刷检(BB),BWF检查项目有:TB-DNA、CEA、细菌培养及脱落细胞,结果36例确诊34例,确诊率94.4％,其中周围型肺癌15例(44％),结核11例(32％),慢性炎症6例(18％),肺脓肿2例(6％)。四种诊断方法中,确诊周围型肺癌以TBNA,TBLB,BB法阳性率高,确诊结核以BWF-TB-DNA阳性率高,确诊慢性炎症以TBLB法阳性率高,确诊肺脓肿以BWF细菌培养阳性率高。提示对肺周围型球块病变应将四种活检方法同时依次进行,方能取长补短,提高阳性诊断率。
Thirty-six patients underwent bronchoscopy (BWF), needle aspiration biopsy (TBNA), lung biopsy (TBLB), brush brushing (BB) CEA, bacterial culture and exfoliated cells. The results of 36 cases confirmed 34 cases, the diagnosis rate was 94.4%, including 15 cases of peripheral lung cancer (44%), tuberculosis in 11 cases (32%), chronic inflammation in 6 cases (18% 2 cases (6%). Among the four diagnostic methods, the positive rates of TBNA, TBLB and BB in diagnosed peripheral lung cancer were high, the positive rate of BWF-TB-DNA in diagnosed tuberculosis was high, the positive rate of TBLB in diagnosed chronic inflammation was high, and the lung abscess was confirmed by BWF bacterial culture High positive rate. Tip of the lung around the ball-type lesions should be four biopsy method at the same time in order to learn from each other to improve the positive diagnostic rate.
