Small (2 cm) peripheral lung lesions and ground glass opacities remain a difficult subset of lung lesions for the diagnosis and management of lung cancer. Surgical biopsy is more difficult for these lesions because intraoperative localization has to be made without the aid of direct visualization or manual palpation. Electromagnetic navigation bronchoscopy can be used in the operating room to identify a small peripheral lesion and marked using an injection of methylene blue, which can be seen on the visceral pleura of the lung. We present our initial experience using this technique. The sample was eight patients who had peripheral lesions with an average size of 19 mm. Surgical wedge biopsy was diagnostic in all cases, with an average procedure time of 28 minutes. There were no complications from this procedure. In conclusion, these data suggest that electromagnetic navigation bronchoscopy can be performed safely with high diagnostic accuracy by the operating thoracic surgeon, but further data are needed to establish its utility and safety.
小的（2厘米）周边肺部病变和磨玻璃影仍是肺癌诊断和管理中较难处理的一类肺部病变。对于这些病变，手术活检难度更大，因为术中定位必须在没有直接可视化或手动触诊辅助的情况下进行。电磁导航支气管镜可在手术室用于识别小的周边病变，并通过注射亚甲蓝进行标记，亚甲蓝在肺的脏层胸膜上可见。我们展示了使用该技术的初步经验。样本为8例患有平均大小为19毫米的周边病变的患者。所有病例手术楔形活检均具有诊断价值，平均手术时间为28分钟。该手术无并发症。总之，这些数据表明胸外科手术医生可安全地进行电磁导航支气管镜检查，诊断准确性高，但需要更多数据来确定其效用和安全性。
