title: Endobronchial Ultrasound Bronchoscope Damage.
abstract: Endobronchial ultrasound (EBUS)-guided transbronchial needle aspiration is an effective, safe, and cost-effective diagnostic bronchoscopy technique for the work-up of mediastinal lymphadenopathy. Concern has been raised, however, about the high cost of convex-probe EBUS bronchoscope repairs. The damage is usually due to breakage of the insertion tube (the flexible part that is advanced into the airways), moisture invasion and damages to the working channel, image guide bundle, or umbilical cord. Understanding the root cause of EBUS scope damage is important for its prevention. We describe 2 unusual cases of EBUS scope damage. In the first case, the distal black rubber covering of the EBUS scope insertion tube was damaged due to friction with the edge of an endotracheal tube and in the second case, the EBUS scope insertion tube was angulating laterally instead of vertically during the flexion maneuver, probably due to scope manipulation while wedged tightly in a segmental bronchus.
