目的评价透视定位下行纤维支气管镜检查诊断肺内孤立性病变的阳性率及安全性。方法回顾性总结88例肺内孤立性病变患者应用DSA透视定位行纤支镜检查,经支气管肺活检(TBLB)、刷检(BB)和支气管肺泡灌洗(BAL)检查的结果,分析影响诊断阳性率的相关因素。结果有52例患者获诊断结果,诊断率59.1%(52/88),其中恶性病变诊断率65.3%(49/75),良性病变诊断率23.1%。病灶大小和病灶部位与诊断阳性率相关。结论透视定位下行纤维支气管镜检查是诊断肺内孤立性病变的有效方法,特别对直径>2 cm、位于近肺门区和中间区的病灶有意义。
Objective To evaluate the positive rate and safety of fluoroscopic bronchoscopy in the diagnosis of isolated solitary pulmonary lesions. Methods Eighty-eight cases of solitary pulmonary lesions were retrospectively reviewed. The results of bronchofulmonary biopsy (TBLB), brush test (BB) and bronchoalveolar lavage (BAL) were analyzed by DSA fluoroscopy, Positive rate of the relevant factors. Results Fifty-two patients were diagnosed, with a diagnosis rate of 59.1% (52/88). The diagnosis rate of malignant lesions was 65.3% (49/75), and that of benign lesions was 23.1%. The size of the lesion and the location of the lesion correlated with the positive rate of diagnosis. Conclusions Positioning fluoroscopy is an effective method for the diagnosis of solitary pulmonary lesions, especially for lesions> 2 cm in diameter and near the hilar and medial regions.
