在X线电视指引下,经纤维支气管镜(以下简称纤支镜)取肺活检际本,对周围型肺癌的定性和病理分型有较高的诊断价值。作者于1981年1～6月间曾对20例经X线检查疑为“周围型肺癌”,而痰细胞学检查阴性(18例),常规纤支镜检查无异常发现(2例)的病人进行这一检查,标本获取率为95％(19/20),诊断阳性率为85.7％(12/14)。作者认为,诊断阳性率的高低与下述因素有关:
Under the guidance of X-ray television, the use of fiberoptic bronchoscopy (hereinafter referred to as fibrobronchoscopy) to obtain a lung biopsy specimen has a high diagnostic value for the qualitative and pathological classification of peripheral lung cancer. From January to June 1981, the author had 20 patients suspected of having “peripheral lung cancer” by X-ray examination and negative sputum cytology examination (18 cases). There was no abnormality in routine bronchoscopy (2 cases). For this check, the specimen acquisition rate was 95% (19/20) and the diagnostic positive rate was 85.7% (12/14). The author believes that the positive rate of diagnosis is related to the following factors:
