两种不同方法肺活检的比较

目的　探讨二种不同肺活检方法的临床价值，以提高诊断准确率。方法 回顾我院1988～2000年经影像学、痰细胞学、细菌学及纤维支气管镜 (以下简称纤支镜 )检查不能确诊的患者293例，对两种不同方法的肺活检结果进行比较分析。结果 经皮肺穿刺活检148例，分别采用X线、CT、B超引导方法，其活检阳性率为87.8%；经纤支镜肺穿刺活检145例，活检阳性率为79.3%。并发症发生率分别为23.6%和21.4%。结论 采用肺活检的方法不同，其结果和临床意义不同，经皮肺活检以CT引导下的方式，诊断准确率最高。

Comparision of two different methods for lung biopsy

Objective To increase the positive rate of diagnosis by comparing with two different Methods for lung biopsy.Methods 293 cases were not be positively diagnosed by radiographs、sputum、cytdogy、bacteriology and fiberbronchoscopy from 1988 to 2000.These cases were examined by two different Methods of lung biopsy.Results Lung biopsy through skin conducted by X-ray、CT and B somascope was used in 148 cases and the positive rate is 87.8%;145 cases were examined by fiberbronchoscopy,with 79.3% positive rate.The frequency of complications was respectively 23.6% and 21.4%.Conclusion Different Methods of lung biopsy have different Results and diferent clinical meanings.Lung biopsy conducted by CT has the most accurate rate of diagnosis.
