观察经纤维支气管镜针吸术对肺癌的诊断价值。方法　对 2 2例肺癌患者采用经纤维支气管镜针吸活检、刷检、钳夹活检进行分析。结果　针吸活检 ,刷检 ,钳夹活检阳性率分别是 72 .72 %、6 8.18%、6 3.6 3% ,针吸活检结合刷检阳性率 86 .36 % ;针吸活检结合刷检较单纯钳夹活检对诊断肺癌的阳性率存在显著性差异。结论　经纤维支气管镜针吸活检结合刷检方法简单 ,安全 ,并发症少 ,在不易钳夹活检的肺癌诊断上有一定价值。 To observe the value of bronchoscopy needle aspiration in the diagnosis of lung cancer. Methods Twenty-two patients with lung cancer underwent needle biopsy, brush biopsy and biopsy by fiberoptic bronchoscopy. Results The positive rates of needle biopsy, brush examination and biopsy were 72.72%, 6.18% and 6.36% respectively. The positive rate of needle biopsy combined with brush test was 86.36% There were significant differences in the positive rate of lung biopsy in the diagnosis of lung cancer. Conclusion The fiberoptic bronchoscopy needle aspiration biopsy combined with brushing method is simple, safe, less complications, it is valuable in the diagnosis of lung cancer difficult to clamp biopsy.
