We performed tracheal tube stent operation in a total of six patients of who received endoscopic Nd-YAG laser treatment of tracheal stenosis. Several types of teflon tubes and silicone T-tubes were used for the tracheal stent. The technique of the tube stent was modified from the methods of Mihashi and Montogomery. The teflon tube stent had some problems in terms of fixation in the trachea but was advantageous in terms of manipulation of fiberoptic bronchoscopy in the tube. The silicone Ttube was easer to fix in the trachea but manipulation of the fiberoptic bronchoscope was more difficult in the tube. It is therefore necessary to choose which trachea tube should be used based on the individual case. Dyspnea and pulmonary function improved dramatically after tracheal tube stent, especially PFR and V75 improved threefold over levels before Nd-YAG laser surgery. We consider that the tracheal tube stent resulted in significantly decreased need for exertion for exhalation at high lung volumes than by Nd-YAG laser surgery only.
