CPAP after endoscopic procedures as add-on therapy for the treatment of tracheal stenosis: a case series

Tracheal stenosis represents a possible complication in intubated or tracheotomised patients. Tracheal resection is currently the gold standard for the treatment of complex stenosis while granulomas and simple stenosis (e.g., web-like) are often treated by endoscopic procedures, which do not consistently give satisfactory long-term results, due to frequent relapses. Administering continuous positive airway pressure (CPAP) after endoscopic procedures might represent a new add-on option for the treatment of this complication. In this case series are presented two patients with tracheal stenosis showed after the removal of tracheostomy tube, both treated with CPAP. The results were straightforward: CPAP treatment helped to keep stable the tracheal lumen, without adverse effects. No further endoscopic dilations were necessary thereafter, with a likely positive impact on patients' quality of life and on health expenditure.
