Electromagnetic Navigation Bronchoscopy for Peripheral Pulmonary Lesions (NAVIGATE)

Peripheral pulmonary lesions (PPLs) are increasingly detected on CT screening. Electromagnetic navigation bronchoscopy (ENB) allows bronchoscopic access to peripheral lesions. NAVIGATE was the largest prospective ENB study.

Prospective multicenter study (37 centers, n=1,215) evaluating ENB for PPL biopsy.

Tool-in-lesion confirmation rate: 77.9%. Diagnostic yield: 73% for malignant lesions. Pneumothorax rate: 3.6% (chest tube required: 1.6%). No procedure-related deaths.

ENB is a safe bronchoscopic approach for peripheral lung lesions with acceptable diagnostic yield (~73% for malignancy). Newer robotic bronchoscopy platforms (Monarch, Ion) show improved yields (>80%). ENB is preferred over CT-guided biopsy for central lesions or patients with high pneumothorax risk.

No comparator arm. Diagnostic yield varies by lesion size and location. Newer robotic platforms may supersede ENB.
