- W2315642052 abstract "Tracheal stenosis (TS) requires a precise diagnosis and an experienced operator in both endoscopic and surgical treatment. We describe a case series at a tertiary care teaching hospital. Twenty patients with TS and/or subglottic stenosis were included. All underwent flexible bronchoscopy (FB). Spirometry (SP) was obtained in 8 patients, and helical computed tomography with three-dimensional reconstruction (HCT3D) was obtained in 11 patients. All cases were graded by each modality on a scale of 1 to 3, and the findings were correlated among modalities. Mean follow-up was 11.1 months (range: 3 to 47 mo). Postintubation injury was the most frequent cause of stenosis in 16 patients (80%). Mean stenosis grade±SD was 2.0±0.92 for SP, 2.3±0.86 for FB, and 2.54±0.68 for HCT3D. A significant correlation was found between HCT3D and FB (r=0.76, P<0.01). There was no correlation between SP and FB (r=0.46, P=0.2) or between SP and HCT3D (r=0.68, P=0.13). Treatment was conservative in 8 patients. Eighteen tracheal dilatation procedures were performed in 7 patients (mean: 2.5 dilatations/patient, range: 1 to 6; mean free time between dilatations 109.7±81 d, range: 6 to 210 d). Tracheoplasty was carried out in 7 patients, with tracheal anastomosis in 4 patients and thyroid-tracheal anastomosis in 3 patients. Tracheostomy was required in 1 patient with scleroma. Neither complications nor mortality related to FB was reported. HCT3D has a good correlation with FB. Tracheal dilatation is a viable option for patients who are not surgical candidates and for those with restenosis of tracheal anastomosis." @default.
