In brief
Single-center retrospective study of 21 pediatric patients with symptomatic tracheobronchomalacia treated with thoracoscopic aortopexy from 2009-2018. Symptom resolution occurred in 81% of patients, though 14% required subsequent tracheostomy, with bronchial involvement identified as a potential risk factor.

Aim
Symptomatic tracheobronchomalacia can be fatal. Successful treatment includes aortopexy. We report outcomes of the thoracoscopic approach in a single centre.
Methods
All patients undergoing thoracoscopic aortopexies from 2009 to 2018 were retrospectively reviewed. Data was reported as median (interquartile range). Risk factors for subsequent tracheostomy were analyzed with logistics regression model, p < 0.05 as significant.
Results
Twenty-one patients with mid to distal tracheomalacia (n = 17) and bronchial involvement (n = 4) were determined on bronchoscopy, tracheobronchogram, or CT thorax. Preoperative patient demographics and comorbidities, e.g., gastro-oesophageal reflux disease, prematurity, and cardiac anomalies were recorded. Indications for thoracoscopic aortopexy were apparent life-threatening event(s) (n = 14), recurrent chest infections (n = 5), and failure to wean invasive ventilation (n = 2). Thoracoscopic aortopexies (n = 20) with conversion to open (n = 1) were performed. Intraoperative bleeding (n = 2) occurred, and chest tube (n = 1) was inserted for monitoring. Intraoperative bronchoscopy (n = 17) confirmed improvement of tracheomalacia. Anesthetic time was 140 (90–160) minutes. Postoperatively, 2 patients had dehiscence of the aorta from the sternum. They underwent redo open aortopexy with posterior tracheopexy, and 1 required subsequent tracheostomy. Another 2 patients required tracheostomies. Potential risk factors for subsequent tracheostomy were investigated, and only the association of tracheobronchomalacia was close to significance (OR 16 (95% CI 0.95–267.03), p = 0.05). Follow up duration was 365 (72–854) days. Symptoms resolution occurred in n = 17 (81%) of patients.
Conclusion
Different modalities were used to delineate the site of tracheobronchomalacia and its etiology. Tracheomalacia with bronchial involvement may be a risk factor for subsequent tracheostomy.
