AbstractA Y-shaped tracheo-bronchial tube was designed and used for two patients with carinal stenosis following a lower tracheal resection in one case and a malignant tracheal fistula in the other. The tube consisted of three parts including a Y-shaped, thin-walled, soft silicone stent; a spiral-wire-reinforced main tube; and a curved tracheostomy tube. The stent was inserted easily and comfortably through the tracheostomy under fiberoptic bronchoscopic guidance with minimal local anesthesia. The positioning stability of the tube was excellent because of the carina-shaped structure of the tube end. Resistance to compression was satisfactory due to the embedded spiral wire. The insertion procedure through the tracheostomy was smooth, even in patients whose respiratory condition was severe or critical. Satisfactory phonational activity was also provided by breathing through the hole on the tube back up to the vocal cord. Bronchoscopic inspection was uncomplicated, and the patients themselves could easily clean the stent. Since palliation of the airway obstruction is the main purpose of such a stent for patients with either severe lower tracheal or carinal stenosis, and because of the difficulty of ordinary stent insertion in this part of the airway, this device appears to offer excellent stability and easy insertion of the stent. In addition, the ease of maintenance and suctioning through the tracheostomal end allows for an excellent quality of life in which the patients are able to return to their homes.
