Abstract
Tracheal reconstruction is a challenging field of research for thoracic surgeons. Recent tracheal grafting studies report short observation times, which make it difficult to conclusively evaluate efficacy. Long-term studies examining the durability of artificial trachea strategies are needed. An ideal artificial trachea strategy would allow for no intervention following replacement, but this approach is presently infeasible. Today, interventional bronchoscopic techniques are widely accepted as a follow-up to airway problems after surgery. Our laboratory developed a semiconductor laser method for endobronchial treatment of stenotic implanted artificial trachea grafts. We herein report the results of a pilot study testing the endobronchial laser treatment in a canine model. The laser treatment yielded vigorous airway re-epithelialization on the graft from the native trachea.
