[Nitinol stent implantation in benign esophagotracheal fistula]

The self-expanding nitinol stent is easy to handle and well tolerated. It offers an improved method in the treatment of perforations of the upper aerodigestive tract. It is easily implantable with rigid and flexible endoscopes. A 45-year-old female patient developed a tracheal necrosis after polytrauma and protracted intubation and ventilation. The permanent cuff pressure caused a 5-cm long fistula located at the posterior trachea 3 cm above the carina. After stabilization of the general condition and spontaneous reduction of the fistula length to 2 cm, we implanted the silicon-covered esophageal stent. Daily bronchoscopic examination was done before and after implantation of the stent. Two days after implantation, we were able to remove the blocked tracheostomy tube. Immediately oral nutrition was possible without complications. Because of its easy and fast application without any complications, the new type of nitinol stent is a promising alternative for ear, nose, and throat patients in bad general condition to provide fast and safe treatment in benign tracheoesophageal fistulas.
