目的探讨经支气管镜于活检前、后吸引对诊断支气管镜下可视病变肺癌患者阳性率的影响。方法 170例经活检、细胞学或外科手术确诊的肺癌患者,患者支气管镜下有可直视病变,取材方式为钳夹活检及活检前、后吸引,将活检前吸引与活检后吸引的肺癌诊断阳性率进行比较分析。结果患者活检前及活检后吸引的细胞学检查阳性率比较,差异无统计学意义(P>0.05);111例镜下增生型表现者,活检后吸引细胞学阳性率高于活检前吸引细胞学阳性率,差异有统计学意义(P<0.05);59例镜下浸润型表现者,活检前吸引细胞学阳性率高于活检后吸引细胞学阳性率,差异有统计学意义(P<0.05)。结论支气管镜下联合钳夹活检及针吸两种方式取材,根据病变镜下表现决定活检前后吸引可显著提高肺癌诊断的阳率。
Objective To investigate the influence of bronchoscopy before and after biopsy on the positive rate of lung cancer in the diagnosis of bronchoscopic lesions. Methods One hundred and seventy patients with lung cancer diagnosed by biopsy, cytology or surgery were enrolled in the study. Bronchoscope was used to treat the lesions directly. The biopsy and biopsy were performed before and after biopsy, and the biopsy and lung biopsy were used to diagnose lung cancer Positive rate for comparative analysis. Results There was no significant difference in the positive rate of cytology before and after biopsy (P> 0.05). The positive rate of cytology in 111 cases under microscopy was higher than that in cytology (P <0.05). The positive rate of aspiration cytology before biopsy was significantly higher than that of biopsy positive after cytology (P <0.05), and the difference was statistically significant . Conclusions Bronchoscopic biopsy combined with biopsy and needle aspiration are available. According to the pathological findings under microscope, the pre and post biopsy can significantly improve the positive rate of lung cancer diagnosis.
