Background: Benign stenosis involving the subglottic region represents a major therapeutic challenge.Surgery is the first line of treatment for laryngotracheal stenosis and leads to a high rate of success. Additionally, endoscopic treatment plays an important role for not yet stabilized subglottic stenosis and management of restenosis.Case description: We report a case of a 60-year-old male that came to our attention with a tracheotomy and subglottic stenosis, related with a previous recovery in an intensive care unit for a myasthenic crisis, that required prolonged intubation. The distinctiveness of this challenging case was represented not only by the length of tracheal resection and the presence of tracheotomy, but also by comorbidities (myasthenia gravis, diabetes mellitus associated with steroid therapy). A multidisciplinary approach was permitted to treat the complex tracheal stenosis with surgical intervention (resection/anastomosis) and to manage the postoperative course that was complicated by wound infection and a progressive restenosis. This complication required endoscopic treatments: firstly balloon dilatation and then stent positioning with rigid bronchoscope.
Conclusions:The innovation in respiratory-intensive-care units allowed a prolonged management of mechanical ventilation. Thus, the number of patients that underwent prolonged intubation and/or percutaneous tracheotomy has increased. In our case, the damage to tracheal wall was related to the cuff pressure of orotracheal tube and to the emergency tracheotomy. This fact determinated an increase of tracheal length to be resected. Partial dehiscence and subsequent restenosis are some of the most frequent complications described in the literature (1.5-13.4%). In these cases, the endoscopic approach represented the only possible conservative way to manage the critical situation, aimed to avoid re-tracheotomy, which probably would have been permanent. In some cases, as well as in our one, stent positioning was required in order to stabilise the tracheal wall. Currently, the patient has no symptoms and bronchoscopy showed stent in place without granulomatous tissue. In this case, the surgical resection/anastomosis could not achieve definitive results, the endoscopic approach played an important role in complications management, permitting to restore patency of the airway without tracheostomy, with the aim to remove the stent 10-12 months later. The multidisciplinary approach does not represent the unique point in this manuscript, however it could be seen as key for challenging cases.
