Experience with Transcordal Silicone Stents in Adult Laryngotracheal Stenosis: A Bicentric Retrospective Study.

ABSTRACT

BACKGROUND: Benign stenosis involving laryngeal and upper tracheal structures represents a therapeutic challenge. Open surgery and endoscopic management have to be discussed by a multidisciplinary board in order to evaluate the risk and benefit for each patient. OBJECTIVE: The objective of this retrospective study was to report the experience of two French centers with transcordal silicone stents (TSS) in the endoscopic management of benign laryngotracheal stenosis (BLTS) in adults, with focus on efficacy, safety, and tolerability. METHODS: We performed a retrospective chart review of all cases of BLTS treated with TSS between January 2001 and June 2017 at two tertiary centers in France the Centre Hospitalier Régional Universitaire de Strasbourg and the Hôpital Nord de Marseille. RESULTS: A total of 17 patients were included. Eleven had a tracheostomy at initial management which consisted of 8 T-tubes and 9 strictly endoluminal stents placements. The main complications were minor aspirations in 5 patients (29%), granulation in 3 patients (18%), migration in 2 patients (12%), and severe dysphonia in 3 patients (18%). After a mean duration of 18.3 months, 11 patients (65%) had had their TSS definitely removed, 13 patients were tracheostomy free (76%), and a TSS remained in place in 4 patients (24%). CONCLUSIONS: Adult BLTS treatment with TSS placement is associated with low morbidity and excellent clinical outcomes, with a large proportion of patients free of airway instrumentation on long-term follow-up.
