经支气管针吸术对管壁浸润型肺癌的诊断价值

对24例纤维支气管镜下未见具体肿物仅见管脏受外压，局部管壁粘膜隆起，诊断考虑管壁浸润型肺癌，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。结果示通过病理组织学或细胞学明确诊断为肺癌19例，总阳性率73％。针吸阳性率33％，活检阳性率54％，刷检阳性率29％。提示针吸术对管壁浸润型肺癌有较高诊断价值。三项综合检查提高了对管壁浸润型肺癌的诊断率。24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

Twenty-four cases of doubtful lung cancer with only local bronchialwall swelling were examined by fiberobronchoscopical needle aspiration cytologlc examination. Punch and smear biopsy were done simultaneously. As a result , 19 cases wereidentified as lung cancer (79%) and the positive rates of the transbronchial needle aswell as the punch and smear biopsies were 63%, 54%, 29% respectively. It indicatesthat the transfiberobronchoscopical needle biopsy is more of advantage in the diagnosisof bronchial infiltrative lung cancer and that combination of these three methods wouldfurther elevate the diagnostic potential.
