345例肺癌的纤维支气管镜检查分析

目的　探讨纤维支气管镜对肺癌的诊断价值及影响活检率的因素。方法　报告 1987年～ 1997年纤维支气管镜检查 34 5例肺癌 ,34 5例毛刷 ,2 95例活检。结果　毛刷阳性率 86 0 9% ,活检阳性 6 1 0 2 % ,术后诊断2 32 % ,鳞癌占 38 2 6 % ,不定型 45 5 1%。结论　纤维支气管镜对肺癌的检查是目前可获得细胞学的重要手段 ,活检阳性率与肿瘤部位、类型、镜下不典型及麻醉等因素有关。

Analysis of fiberoptic bronchoscopy in 345 cases of lung cancer

Objective To evaluate diabnostic value of fiberoptic bronchoscopy in lung cancer and factors of influencing positive rate of biopsy.Methods Fiberoptic bronchoscop was conducted in 345 cases of lung cancer.In the course of examination,brushing was performed in all cases,and biopsy in 295 cases.Results The positive rate of brushing was 86 09%,while the positive rate of biopsy was 61 02%.Among all those cases 38 26% was found to be squamous cell cancer and 45 54% to be undetermined type.Conclusion Fiberoptic bronchoscopy is an important approach of cytologic examination in diagnosis of lung cancer.The positive rate of biopsy is related to tumrous site ,type,atypical manifestation and anaesthetization,etc.
