Objective To investigate the feasibility and primary therapeutic effect of Dumon Y-shaped airway stent for complex airway disease (stenosis or fistula). Methods Seven patients with complex airway disease underwent placement of Dumon Y-shaped airway stent via rigid bronchoscope, and selected stent depend on carefully measuring the diameter and length of the stenosis or fistula. We retrospectively analyzed the therapeutic efficacy of the patients placed Dumon Y-shaped airway stent. Results All the Dumon Y-shaped airway stent placed successfully. The diameter of the narrowest tracheal stenosis under the carina was improved significantly from (8.03 ± 5.45) mm to (13.08 ± 3.41) mm after the operation. Medical Research Council dyspnea grade improved significantly from Ⅲ～Ⅳ to Ⅰ～Ⅱ and the oxygen saturation improved significantly from (93.86 ± 1.07) % to (98.14 ± 1.07) %. There is no treatment-related complication and death in the seven patients. Conclusion As a new choice, the technique of Dumon Y-shaped airway stent is feasible and safety for the complex airway disease (stenosis or fistula), and worthy of widely promoting.
