纤维支气管镜检查对痰菌阴性下肺野结核的诊断价值（附45例分析）

报告利用纤维支气管镜诊断痰菌阴性的下肺野结核45例。纤维支气管镜下表现为溃疡性肉芽肿，纤维性狭窄和炎性粘膜充血水肿。经纤维支气管活检病理诊断6例（6／45），刷检涂片诊断16例（16／40），吸检涂片16例（16／42），灌洗液涂片诊断例（8／16）。表明利用纤维支气管镜检查可提高痰菌阴性的下肺野结核的诊断率和了解支气管内膜病变情况。

Diagnostic Value of Fiberoptic Bronchoscopy in Sputum Negative Lower Lung Field Tuberculosis(An Analysis of 45 Cases)

Forty five cases of lower lung field tuberculosis with sputumnegative finding diagnosed by fiber- bronchoscopic examination were reported.The major bronchoscopy findings were ulcerative granulo- ma,fibrostenosis,and inflammatory broncheal mucosa with congestion and edema.In 6 of 45 cases the pathological biopsy was diagnosed tuberculosis,bronchoscopic brushing smear was positive in 16 of 40, bronchoscopic aspirate smear was positive in 16 of 42.BAL(Bronchoalveolar Lavage) smear was posi- tive in 8 of 16.It is suggested that fibroptic bronchoscopy is valuable in detecting pathological and mi- cobiological evidence of lower lung field tuberculosis with smear-negative sputum and assessing the severity of endobronchial lesions.
