目的观察经纤维支气管镜针吸术对肺癌的诊断价值。方法对180例肺癌患者在纤支镜检查的过程中,采用针吸术,结合钳夹、刷检等序贯取材法收集病理标本,分析各种方法诊断肺癌的阳性率。结果针吸活检、钳夹活检、刷检阳性率分别是70%、80%、67%,针吸活检结合钳夹、刷检阳性率91%;3种单独的取材方法,其阳性率差异并无统计学意义(P>0.05);但采用序贯取材法后,诊断肺癌的阳性率明显高于各种单独的取材方法,差异有统计学意义(P<0.01)。结论纤支镜检查对肺癌的诊断有重要价值,对于疑似肺癌患者应尽可能联合使用多种取材方法,以提高纤支镜检查对肺癌的诊断率。
Objective To observe the value of fiberoptic bronchoscopy needle aspiration in the diagnosis of lung cancer. Methods 180 cases of lung cancer patients in the process of fiberopticoscopy, needle aspiration, combined with clamp, brushing and other sequential method to collect pathological specimens, analysis of various methods to diagnose the positive rate of lung cancer. Results The positive rates of needle biopsy, biopsy and brushing were 70%, 80% and 67%, respectively. Needle biopsy combined with jaws and brushing positive rate was 91%. There were three different methods of harvesting and their positive rates were different (P> 0.05). However, the positive rate of diagnosis of lung cancer after sequential radiography was significantly higher than that of other methods (P <0.01). Conclusion Bronchofiberscopy is of great value in the diagnosis of lung cancer. For patients with suspected lung cancer, a variety of methods should be used in combination as much as possible to improve the diagnostic rate of bronchoscopy for lung cancer.
