目的评价 CT引导纤维支气管镜经支气管肺活检 (CT-TBLB)和经皮肺穿刺活检 (CT-NL B)在肺周围性病变中的综合应用价值。方法根据病灶处在肺野位置不同 ,5 1例选择 CT-TBL B,46例采用 CT-NL B。结果综合选择下两组肺活检取材总成功率达 10 0 % ,阳性率 87.6% ,诊断符合率 97.9% (其中 CT-TBLB达 10 0 % ) ,气胸和咯血等并发症明显较少。两种方法阳性率和符合率较高 ,但组间无显著性差异 (P均 >0 .0 5 )。结论 CT-TBLB和 CT-NL B是肺周围性病变定性诊断可行的和理想的非开胸活检方法 ,适合不同位置类型病灶。若综合选用可提高肺周围活检的准确性和安全性。
Objective To evaluate the value of CT-guided bronchofibroscopy in bronchogenic lung biopsy (CT-TBLB) and percutaneous lung biopsy (CT-NL B) in the treatment of peripheral pulmonary lesions. Methods According to the location of the lesion in the lung field, CT-TBL B was selected in 51 cases and CT-NL B in 46 cases. Results The overall success rate of lung biopsy in the two groups was 100%, the positive rate was 87.6%. The coincidence rate of diagnosis was 97.9% (CT-TBLB was 100%). There were less complications such as pneumothorax and hemoptysis. The positive rate and coincidence rate of the two methods were higher, but there was no significant difference between the two groups (P> 0.05). Conclusion CT-TBLB and CT-NL B are feasible and ideal non-thoracotomy biopsy methods for the qualitative diagnosis of peripheral pulmonary lesions. They are suitable for different types of lesions. If the comprehensive selection can improve the accuracy and safety of biopsy around the lungs.
