Summary

A limitation of current approaches to peripheral lesions may be the caliber of bronchoscope used to reach them. As peripheral airways taper further in size, the ability of the bronchoscopist to approximate peripheral lesions diminishes using conventionally sized bronchoscopes of 5 or 4mm in outer diameter. Because of this limitation, the bronchoscopist may be unable to cannulate peripheral airways that lead directly to targeted lesions, thereby significantly compromising the diagnostic yield of the procedure. Ultrathin bronchoscopy utilizing bronchoscopes of 3mm in outer diameter may allow bronchoscopists better access to the lung periphery, thereby allowing access to peripheral airways that may lead directly into targeted lesions, resulting in a concentric anatomical position, where diagnostic yields may be improved.
