几乎凡接受支气管镜检的病人,通常都要作经支气管的肺门淋巴结穿刺。在1841病人中穿刺数达1883次之多。形态学上证明为恶性病症的有84%在涂片上证明了肿瘤细胞,而在97例类肉瘤中则有94%作出了细胞学的诊断。由于相对与纵膈障镜检和胸腔镜检比较来说,其准确性高,操作无危险性,以及病人负担最小,当纵膈障病情不明时,以及为了确定支气管 Almost all patients undergoing bronchoscopy usually undergo transbronchial hilar lymph node puncture. There were as many as 1,883 punctures in 1841 patients. 84% of the morphologically proven malignant lesions demonstrated tumor cells on the smear, while 94% of 97 rheumatoid sarcomas had cytological diagnosis. Because of its relative accuracy compared with longitudinal patency and thoracoscopy, its accuracy is high, the operation is non-risk, and the patient’s burden is minimal, when the medial stricture is unclear, and in order to determine the bronchus
