Current opinion in pulmonary medicine

Peripheral pulmonary lesions (PPL) are being diagnosed with increasing frequency, especially with the increased use of chest computed tomography (CT). Depending on the location and size, these lesions often present a diagnostic challenge in terms of the low yield of traditional bronchoscopic biopsy techniques or the risks of a percutaneous biopsy approach. ⋯ These advanced bronchoscopic techniques play an increasingly common role in the evaluation and biopsy of PPL. Electromagnetic navigation bronchoscopy and radial endobronchial ultrasound are the most commonly used guided techniques either in isolation or in combination and have the most published data regarding clinical experience and diagnostic yield; however, none of the techniques have consistently matched the yield of CT-guided trans-thoracic needle biopsy for PPL. Overall the complication rate of image-guided bronchoscopy techniques is low with pneumothorax being the most common adverse event.
