Introduction: Benign tracheal stenosis (BTS) is a debilitating condition requiring urgent treatment. However, there is still no consensus on the best management option. We aim to describe the efficacy and safety of bronchoscopic treatment (BT) for BTS.
Methods: Retrospective unicenter study including all patients diagnosed with BTS, from 2008 to 2018, that were submitted to BT. Stenoses were classified as simple in granulomas, web-like or concentrical stenosis and if ≤1cm in vertical extension; and as complex if >1cm extension or if associated with tracheomalacia or cartilage involvement.Therapeutic techniques used were mechanical dilation with balloon and/or tracheoscope, argon-plasma coagulation and mitomycin-C. Silicon stent was placed when non-satisfactory tracheal lumen patency (>50% of the normal lumen) was achieved by the previous techniques.After first treatment,further interventions were performed in case of symptomatic stenosis recurrence. Patients were considered cured if there were no recurrence after 1 year of the last therapeutic intervention, over a 2-year follow-up period.
Results: 25 patients were included: 15 females (60.0%); mean age 38.4 ± 26.1 years; submitted to 60 therapeutic procedures. Stenoses were secondary to tracheostomy in 11 patients (44.0%), endotracheal intubation in 10 (40.0%) and tracheobronchopathia osteochondroplastica in 1 (4.0%).In 3 cases (12.0%) were considered idiopathic.BTS were classified as simple in 9 cases (36.0%) and complex in 16 (64.0%).The median follow-up time after diagnosis was 4 years (IQR 1.0 - 8.8). During that period,the group of simple stenoses were submitted to total of 18 procedures with a mean of 1.64 procedures per patient.No silicon stents were used.66.7% of patients were successfully cured trough BT.The remaining (n=3,12.0%) died before completing follow-up. One death (4.0%) was considered procedure-related, secondary to haemoptysis in the 24h post-BT. In the complex stenosis group, a total of 42 procedures were performed with a mean of 2.47 procedures per patient. Silicon stent was placed in 6 (23.1%) patients. 62.5% of patients were cured through BT. From the remaining, 3 (12.0%) had symptomatic stenosis recurrence after stent removal, with need for stent replacement and continue palliative BT, and 3 (12.0%) died before completing follow-up. No death was procedure related.
Conclusion: In our population, BT was shown to be an effective and safe treatment in long-term BTS management, with only one procedure-related death. Even in complex stenosis, high cure rate was achieved by this technique.
