CT引导纤维支气管镜对小支气管源性癌的活检价值

目的：探讨CT引导纤维支气管镜(纤支镜)对小支气管源性癌的活检价值。方法：33例CT引导纤支镜活检结果与手术病理对照并与纤支镜盲检及CT引导经皮肺穿刺活检比较。结果：单纯1～3级大支气管内病变，可采用纤支镜直视活检；小支气管内病变以CT引导纤支镜活检更为可靠、准确和并发症少；细支气管及肺泡病变则以CT引导经皮肺穿刺活检成功率高。结论：对发生于小支气管内的较小病灶，CT引导纤支镜活检，可以采集到更全面的病理标本，并通过镜检 刷检 多点活检技术的综合应用，能进一步提高活检的准确性。

Value of CT guided fiberbronchoscopic biopsy of carcinoma originating from small bronchiole

Objective To evaluate the value of CT guided branchofiberoscopic biopsy of carcinoma originating from small bronchiole. Methods The fiberbronchoscopic biopsy results of 33 cases under CT guidance were compared to the results of surgical pathology, including fiberbronchoscopic blind examination and CT guided percutaneous lung biopsy. Results The lesions occurred in 1 - 3 grade bronchus could be approached with fiberbronchoscopic biopsy under direct vision. CT guided fiberbronchoscopic biopsy had the benefit of getting more reliable, accurate samples simultaneously with less complications in the diagnosis of bron-chiolar lesions. It was more easy and having higher positive rate to diagnose the lesion of terminal bronchiole and alveoli by CT guided percutaneous lung biopsy. Conclusions CT guided fiberbronchoscopic biopsy can collect more wholesome pathologic specimen than other examinations for small lesions of bronchus. The comprehensive utilization of microscopy, brush biopsy and multiple sites biopsy can improve the accuracy.
