经支气管针吸术对管壁浸润型肺癌的诊断价值

目的探讨支气管针吸术对管壁浸润型肺癌的诊所价值及安全性。方法48例纤维支气管镜下未见具体肿物仅见管腔受外压，局部管壁黏膜隆起，诊断考虑管壁浸润型肿癌，采用经支气管针吸术细胞学检查，并同时行活检及刷检进行对照。结果通过病理组织学或细胞学明确诊断为肺癌38例，总阳性率79％。针吸阳性率63％，活检阳性率54％，刷检阳性率29％。结论针吸术对管壁浸润型肺癌有较高的诊断价值。三项综合检查提高了对管壁浸润型肺癌的诊断率。48例除仅有部分穿刺部位极少量出血外，无其他并发症。

Role of needle biopsy in the diagnosis of bronchial wall infiltration in lung cancer

Objective:To explore role of needle biopsy in the diagnosis of bronchial wall intiltration in lung cancer.Methods:Forty-eight cases of doubtful lung cancer with only local bronchial wall swelling were examined by fiberobronchoscopical needle aspirasion eytologic examination.Punch and smear biopsy were done simultaneous-ly.Results:38cases were identified as lung cancer(79%)and the positive rates of the transbronchial needle as well as the punch and smear biopsy were63%,54%and29%respectively.Conclusions:Thtransfiber bronchoscopical needle biopsy is more of advantage in the methods,and would further elevate the diagnostic potential.
