电磁导航支气管镜系统在呼吸系统疾病诊治中的应用现状与展望

摘要

Bronchoscopy is a minimally invasive method for obtaining peripheral pulmonary lesions (PPL). Traditional bronchoscopy-guided transbronchial lung biopsy (TBLB) is performed under X-ray guidance, and diagnostic rate is relatively low. A new, real-time electromagnetic navigation bronchoscopy (ENB) is a minimally invasive diagnostic technique which appeared in recent years. Studies suggest ENB is a feasible and safe method for diagnosis of PPL which shows higher diagnostic yields than traditional TBLB, and its potential application in localization and treatment of PPL. This article reviews the clinical application of the technique.%支气管镜为获取肺外周病变(peripheral pulmonary lesions，PPL)的一种微创技术。传统支气管镜引导的经支气管肺活检(transbronchial lung biopsy，TBLB)在X线透视指导下进行，诊断率相对较低。电磁导航支气管镜(electromagnetic navigation bronchoscopy，ENB)是近年来出现的一项新的微创诊断技术。其对PPL诊断率优于传统经支气管镜。多项研究已显示出ENB诊断PPL具有的可行性和安全性，并且显示出ENB在PP定位和治疗领域具有潜在的应用前景。该文就这一技术临床应用现状作一综述。
