Abstract

Purpose: Bronchoscopy for peripheral pulmonary lesions continues to present challenges to clinicians. One potential limitation may be the inability to advance conventional bronchoscopes into close proximity of peripheral lesions before biopsy. This study was performed to assess the reach of a robotic endoscopic system within human cadaveric lungs compared with conventional thin bronchoscopes. Description: All segmental bronchi (RB1 to 10, LB1 to 10) were accessed in two human cadavers using a conventional thin bronchoscope and robotic endoscope of identical outer diameter. Bronchus generation count and insertion depth measured by electromagnetic navigation and external fluoroscopy were recorded. Evaluation: The robotic endoscope was advanced beyond the conventional thin bronchoscope in all segments, particularly in bronchi with increased angulation such as RB1 (mean generation count 8 versus 3.5, respectively) and LB1+2 (mean generation count 8 versus 4.5). Conclusions: The robotic endoscopic system was advanced beyond a conventional thin bronchoscope with identical outer diameter into the periphery of human cadaveric lungs. Improved reach within the lung periphery may address some limitations with contemporary bronchoscopic approaches for peripheral lesion biopsy.
