Background: Electromagnetic navigation bronchoscopy is a tool that can accurately navigation peripheral lung lesions. Because of electromagnetic navigation bronchoscopy (ENB) is too expensive, it has not been widely used in China. It is urgent for us to summarize experience in clinical application, especially in the diagnosis of pulmonary nodules.
Methods: The clinical data of patients with pulmonary peripheral lesions (PPLs) in our department undergoing ENB biopsy between July 2017 and December 2018 were retrospectively analyzed.
Results: There were 18 patients with 21 PPLs (10 males and 8 females). Among them, 11 patients got the final pathological diagnosis, 8 cases were diagnosed with adenocarcinoma lung cancer, 1 case was diagnosed with tuberculosis and 2 cases were diagnosed with small cell lung cancer. The positive rate of diagnosis was 61.1%. The sensitivity was 73.3%. The positive diagnosis rate is related to the size of the lesion, the positive diagnosis rate for lesions >2 cm is 100.0% (P=0.04).
Conclusions: Electromagnetic navigation bronchoscope is safe and effective in clinic. It has a high positive rate for the diagnosis of peripheral lung lesions larger than 2 cm, ENB has broad clinical application prospects.
【中文题目：电磁导航支气管镜在肺外周结节诊断中的应用】 【中文摘要：背景与目的 电磁导航支气管镜是一种能够进行肺部病变精准定位的工具，在肺部病变诊断中具有重要价值，但由于价格昂贵，在我国应用尚未普及，急需总结其在临床中的应用，尤其是肺部结节诊断中的经验。方法 回顾性分析我科2017年7月-2018年12月诊断为肺外周病变，且行电磁导航支气管镜检查患者的临床资料，总结其应用经验。结果 18例患者（男性10例，女性8例），共21处病变，11例诊断明确，8例诊断为肺腺癌，1例诊断为肺结核，2例诊断为小细胞肺癌，诊断阳性率为61.1%，敏感性为73.3%，诊断阳性率与病变大小相关，>2 cm病变诊断阳性率为100.0%（P=0.04）。结论 电磁导航支气管镜在临床中安全有效，对于病变>2 cm的肺外周病变诊断阳性率较高，有着广阔的临床应用前景。】 【中文关键词：电磁导航支气管镜；肺外周病变；活检】.
