This study evaluates the efficacy of treating postintubation trachea stenosis with stent implantation. Twenty-two patients with postintubation trachea stenosis were treated with stent insertion (21 silicone stents and 1 Gianturco stent). The stenoses were detected 107 days after an average of 14 days of mechanical ventilation. If the laser photocoagulation and/or mechanical dilatation were ineffective and the stricture recurred, a stent was implanted after the second dilatation procedure. A 1-year follow-up showed that stent implantation significantly improved the quality of life for 13 patients considerably restricted by tracheal stenosis. Nine interventions were unsuccessful (3 patients required surgical resection, 5 required Montgomery T-tube implantation, and 1 died because of unresolved main airway stenosis). These results indicate that stents are effective in the maintenance of airway patency in postintubation stenosis. The stent should be removed no earlier than 10 months after implantation. In cases of restenosis, surgical resection or Montgomery T-tube implantation are the choices of therapy.
