电子支气管镜及刷检对支气管结核诊断价值

Diagnostic value of electronic bronchoscopy and brush biopsy for bronchial tuberculosis

目的探讨电子支气管镜及刷对支气管结核诊断价值。方法分析48例支气管结核患者检查前痰结核杆菌涂片结果与电子支气管镜检查及刷检的结核分枝杆菌均快速培养及结核均培养的阳性率。结果镜下炎性浸润型28例占58.33%、溃疡坏死型4例占8.33%、瘢痕狭窄型9例占18.75%、肉芽增生型3例占6.25%、淋巴瘘型3例占6.25%、管壁软化型1例占2.08%,痰结核杆菌涂片阳性率35.4%,刷检的结核分枝杆菌快速培养阳性率50%,刷检的结核菌培养的阳性率60.4%。结论电子支气管镜及刷检的结核分枝杆菌快培养及结核菌培养对支气管结核有重要的诊断价值,刷检的结核菌培养明显优于痰结核杆菌涂片阳性率,支气管结核以炎性浸润性为主。

Objective To evaluate the diagnostic value of electronic bronchoscopy and bronchial brush in bronchial tuberculosis.Methods The results of sputum tuberculum smear,electronic bronchoscopy,and bronchial brush were analyzed in 48 patients with bronchial tuberculosis before examination.Results Under the microscope,there were 28 cases of inflammatory infiltrating type(58.33%),4 cases of ulcer necrosis type(8.33%),9 cases of cicatricial stenosis type(18.75%),3 cases of granulomatous hyperplasia type(6.25%),3 cases of lymphatic fistula type(6.25%),and 1 case of tube wall softening type(2.08%).The positive rate for rapid culture using brush mycobacterium tuberculosis was 50%,while that for culture using brush mycobacterium tuberculosis was 60.4%.Conclusion Rapid culture of Mycobacterium tuberculosis through electronic bronchoscopy and bronchial brush is highly valuable in diagnosing bronchial tuberculosis.The positive rate for culture using the brush method is significantly higher than that for sputum smears.
