Robotic Navigational Bronchoscopy Combined with Needle-Based Confocal Laser Endomicroscopy: Case Report of a Novel Approach to Diagnose Small Lung Nodules

Abstract

Lung cancer is the most commonly diagnosed cancer and the leading cause of cancer-related death. Advancements in navigational bronchoscopy have shown encouraging results but the diagnostic yield of small lung nodules by bronchoscopic techniques is still below that of transthoracic needle aspiration. The development of robotic bronchoscopy has demonstrated a significantly improved navigational success but the diagnostic yield is regularly limited by near-miss of the target nodule. Needle-based confocal laser endomicroscopy is a novel imaging technique that allows for the real-time visualization of individual cells and structures with microscopic resolution at the tip of the needle. We present the first reported case of confocal laser endomicroscopy guided robotic bronchoscopy for the real-time diagnosis of a small, partially cystic lung nodule.
