In this chapter we will discuss two bronchoscopic advances in the diagnosis and staging of lung cancer.
Endobronchial ultrasound utilizes a flexible ultrasound probe fed through the working channel of a bronchoscope to image and biopsy lesions and lymph nodes beyond the wall of the bronchus. Electromagnetic navigation and guidance involves a specialized electromagnetic table with a computer program that maps the endobronchial tree and then helps navigate a bronchoscope to a particular lesion or lymph node.
We review a number of recent studies that utilize endobronchial ultrasound and electromagnetic navigation and guidance and analyze their performance characteristics for lung cancer diagnosis and staging as well the clinical applications of both technologies. Both are likely to play an increasing and integral role in the diagnosis and staging of lung cancer in the near future. Endobronchial ultrasound will likely have its greatest impact on mediastinal lymph node staging while electromagnetic registration may impact both staging and diagnosis of peripheral lesions.
在本章中，我们将讨论肺癌诊断和分期方面的两项支气管镜检查进展。
支气管内超声利用通过支气管镜工作通道插入的柔性超声探头，对支气管壁外的病变和淋巴结进行成像及活检。电磁导航与引导涉及一张配有计算机程序的专用电磁台，该程序可绘制支气管树图谱，然后帮助将支气管镜引导至特定病变或淋巴结。
我们回顾了一些近期利用支气管内超声以及电磁导航与引导的研究，并分析了它们在肺癌诊断和分期方面的性能特征以及这两种技术的临床应用。在不久的将来，这两种技术都可能在肺癌的诊断和分期中发挥越来越重要且不可或缺的作用。支气管内超声可能对纵隔淋巴结分期产生最大影响，而电磁定位可能对周围病变的分期和诊断都有影响。
