我们对296例肺癌在纤维支气管镜检查时作活检、刷检及术后痰检,275例阳性、阳性率为92.91%.单项阳性率活检为79.47%,刷检为71.94%.如同时作活检及刷检,阳性率可提高到92.94%,而三项同时进行时,阳性率为96.55%.本组术后痰检的阳性率较低(26.76%),可能由于我们术后即刻留痰一次所致.纤支镜可见病变者活检、刷检阳性率分别为80.38%及73.64%.未见病变者阳性率较低.本组有1例,在X线透视下,于病变部位作肺活检,结果阳性.今后我们应尽量在X线透视下作肺活检.术后多次连续痰检也可望提高阳性率.
We performed biopsy, brush examination and postoperative sputum examinations on 296 cases of lung cancer, with a positive rate of 92.91%, with a positive rate of 79.47% and a brushing rate of 71.94% .Both biopsies And brush test, the positive rate can be increased to 92.94%, while the three simultaneously, the positive rate was 96.55% .This group of postoperative sputum examination of the positive rate was low (26.76%), may be due to our immediate stay after a sputum Due to fiberoptic bronchoscopy lesions can be seen biopsy, brushing positive rates were 80.38% and 73.64% .The positive rate of no lesion was lower in this group in 1 case, under the X-ray examination in the lesion for lung biopsy , The results were positive in the future we should try lung biopsy under X-ray after multiple consecutive sputum examination is also expected to improve the positive rate.
