BACKGROUND: Decannulation is the ultimate therapeutic goal for patients who undergo stenting because of inoperable benign tracheal stenosis. In this study, our objectives were to evaluate whether long-term airway stenting allows decannulation in patients with benign tracheal stenosis who were deemed inoperable and to identify possible predictive factors for successful decannulation (SD).
METHODS: Retrospective cohort study including all patients with inoperable benign tracheal stenosis who underwent tracheal stenting in our tertiary-care university-based institution from 1998 to 2008. For benign stenosis, we use only silicone stents (T tubes, Dumon stents, and Y stents). The main outcome was SD, which was defined as removal of the tracheal stent followed by absence of respiratory symptoms and no requirement for new dilation procedures for at least 6 months. A Kaplan-Meier curve was built to evaluate SD in 5 years, and we used a Cox model to evaluate predictors for a SD.
RESULTS: Ninety-two patients were included, and during the study period 21 were decannulated. However, 2 of them had to undergo new airway procedures and were considered to represent failure. Therefore, 19 patients were successfully decannulated. According to the Kaplan-Meier estimate, the SD rate in 5 years was 27.5%. The mean follow-up time after SD was 34.3 ± 33.9 months (range, 6 to 108 months). Cox regression showed only 1 significant factor: tracheostomy before stent insertion caused a threefold increase in the likelihood of the patient remaining with a tracheal stent (p = 0.048).
CONCLUSIONS: Tracheal stenting may be considered a curative therapeutic approach in as many as 27.5% of patients with inoperable benign tracheal stenosis.
