本文报道48例胸腔积液作胸膜活检的资料分析。成功率为85.5％,阳性诊断率为42.1％,恶性胸的诊断率为46.2％,结核性为33.3％。因病变在胸膜表面呈分散存在,故活检应反复多次进行。本文在第一次活检阳性为53.8％,而第4次或更多次即无阳性发现,因此如第3次活检阴性者即无需再作活检,我们曾比较了胸膜活检与胸水脱落细胞检查的阳性率。前者较高,但无统计学意义。故如无脓胸或出血倾向等禁忌症者,在胸腔抽液时均应作活检以提高阳性率。
This article reports 48 cases of pleural effusion for pleural biopsy data analysis. The success rate was 85.5%, the positive diagnosis rate was 42.1%, the diagnosis rate of malignant thorax was 46.2% and tuberculosis was 33.3%. Due to the presence of lesions in the pleural surface dispersed, so biopsy should be repeated many times. This article in the first biopsy positive was 53.8%, and the fourth or more times that is no positive findings, so if the third biopsy negative that no need for biopsy, we have compared the pleural biopsy and pleural effusion cytology Positive rate. The former is higher, but not statistically significant. Therefore, such as no empyema or bleeding tendency and other contraindications in the chest fluid should be biopsy to improve the positive rate.
