[目的]探讨在高分辨率CT片定位下,气管镜下刷检对位于肺第5～9级支气管间的肺占位性病变的诊断价值。[方法]对85例肺部肿块位于肺第5～9级支气管间的患者,术前在高分辨率CT片定位下行支气管镜下刷检细胞学检查,以细胞病理学结果为诊断依据。[结果]经支气管镜肺刷检总阳性率为44.71%,其中非小细胞癌20例,小细胞癌18例。所有患者术后均未发生气胸、肺内大出血等严重并发症。[结论]高分辨率CT片定位下对位于第5～9级支气管的病灶进行超选择性的刷检具有一定的诊断价值。
[Objective] To explore the value of bronchoscopic brushing in the diagnosis of lung-space occupying lesion located in grade 5 ~ 9 bronchus in lung under high-resolution CT slice location. [Method] Totally 85 patients with lung mass located in bronchial grade 5-9 in the lung were examined by bronchoscopy under high-resolution CT before operation. Cytological results were used as the diagnostic basis. [Results] The positive rate of bronchoscopy was 44.71%, among which 20 were non-small cell carcinoma and 18 were small cell carcinoma. No severe complications such as pneumothorax or intrahepatic hemorrhage occurred in all patients. [Conclusion] The high resolution computed tomography (CT) positon imaging has the certain diagnostic value for the super selective brushing of the lesions located in the bronchial tubes of grade 5 ~ 9.
