Improvement in postoperative lung function in patients with moderate to severe airway obstruction after robotic-assisted thoracoscopic tracheobronchoplasty.

Robotic-assisted thoracoscopic tracheobronchoplasty improves obstruction and symptoms. With limited follow-up, subgroup analysis showed forced expiratory volume in 1 second improved in severe preoperative obstruction and quality of life improved in moderate obstruction. Future follow-up is required to determine robotic-assisted thoracoscopic tracheobronchoplasty effects on the most severe group, but we cannot conclude that increased degree of preoperative obstruction precludes surgery.
