title: A simple technique to control placement of Dumon stent in subglottic tracheal stenosis.
abstract: Airway stenting is the chosen treatment for patients affected by subglottic tracheal stenosis and unfit for surgery. Among the different types of prostheses, the Dumon stent is a valid option especially in patients without tracheotomy. Insertion is usually achieved by pushing the stent off from a loader using a prosthesis pusher. If the stent is expelled below the stenosis, rigid forceps grasping the proximal end of the stent retract it above the stenosis. However, in difficult cases such as rigid stenosis with a luminal diameter smaller than the profile of the stent, such a manoeuvre may be difficult in non-expert hands. Thus, we proposed a simple and safe technique to facilitate the placement of a Dumon stent. We passed a long thread from outside to the inside of the stent. After the dilatation of the stenosis, the stent was pushed and, if needed, easily retracted with the thread into the proper position to ensure airway patency and to avoid migration. In addition, our procedure could be useful also to rapidly remove the stent if its size turned out to be inaccurate for the stenosis. With such a simple method we successfully treated 7 consecutive patients affected by complex subglottic stenosis and unfit for surgery.
