ObjectiveThe study objective was to examine pulmonary function and quality of life improvement after robotic-assisted thoracoscopic tracheobronchoplasty for patients with different degrees of obstructive airway disease.MethodsWe performed a retrospective review of a prospective database of patients who underwent robotic-assisted thoracoscopic tracheobronchoplasty between 2013 and 2020.ResultsA total of 118 patients underwent robotic-assisted thoracoscopic tracheobronchoplasty. Preoperative and postoperative pulmonary function tests were available for 108 patients. Postoperative pulmonary function tests at a median of 16 months demonstrated a significant increase in percent predicted forced expiratory volume in 1 second (preoperative median: 76.76% predicted, postoperative: 83% predicted, P = .002). Preoperative and postoperative St George Respiratory Questionnaires were available for 64 patients with a significant decrease in postoperative score at a median of 7 months (preoperative median: 61, postoperative: 41.60, P < .001). When stratified by preoperative degree of obstruction, robotic-assisted thoracoscopic tracheobronchoplasty improved forced expiratory volume in 1 second in moderate to very severe obstruction with a statistically significant improvement in moderate (preoperative median: 63.91% predicted, postoperative median: 73% predicted, P = .001) and severe (preoperative median: 44% predicted, postoperative median: 57% predicted, P = .007) obstruction. St George Respiratory Questionnaire scores improved for all patients. Improvement for mild (preoperative median: 61.27, postoperative median: 36.71, P < .001) and moderate (preoperative median: 57.15, postoperative median: 47.52, P = .03) obstruction was statistically significant.ConclusionsRobotic-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.Copyright © 2022 The American Association for Thoracic Surgery.
