Direct Insertion of Dumon Stents for Patients With Permanent Tracheal Stoma

Abstract

Dilation of the airway by means of stenting is a standard strategy for airway stenosis. The Dumon stent, a typical stent made of silicone, is usually inserted through a rigid bronchoscope, however that technique is unable to be performed in patients with permanent tracheal stomas. We need to consider the best way to manage stent insertion for those patients. Cases. We encountered two cases of tracheal stenosis with permanent tracheal stoma after surgery for hypopharyngeal carcinoma, and directly inserted Dumon stents into their tracheas. Patients were maintained with spontaneous respiration under intaravenous and inhalation anesthesia. Dumon stents were folded and directly held with Kelly forceps matched with the curve of the trachea. The stents were inserted through the portion of stenosis using video-fluoroscopy. Stentings were performed promptly and safely in both cases and their dyspnea improved distinctly after operation. Conclusion. Insertion of Dumon stent for patients with permanent tracheal stoma was performed easily using curved Kelly forceps. Grasping of the folded stent by Kelly forceps is the key point of the technique.
