The role of T-tubes in the management of airway stenosis

OBJECTIVES When the T-tube is inserted as a temporary stent, it is unclear whether keeping it longer in place has any benefit on the outcome. METHODS Among 1738 patients with airway stenosis (1996-2011), 134 underwent T-tube placement (mean duration = 14.3 months); temporarily while waiting for an appropriate time for surgery in 53 (Group 1), as an adjunct after a complex laryngotracheal resection in 27 (Group 2), after surgical failure in 43 (Group 3) and permanently in 11 unresectable strictures (Group 4). A logistic regression model was used for statistical analysis. RESULTS Seventy percent of patients were males (age = 33.6 ± 17 years). The main cause was postintubation/post-tracheostomy stenosis in 87% of patients. The stenosis (29.6 ± 14 mm, 5-80 mm) was located in the subglottis in 33%, trachea in 47% and both in 20% of cases. To assess the effect of T-tubes on stabilizing the airway after decannulation, 50 patients who still had a T-tube at the end of follow-up or for 6 months may increase the chance of successful decannulation, it was not confirmed in our study.
