The first comparative analysis of open and robotic tracheobronchoplasty for excessive Central airway collapse.

Abstract

Objectives: Tracheobronchoplasty is an operation to treat excessive central airway collapse by stabilizing the posterior tracheal membrane. In 2020, our institution transitioned from the traditional open approach to the robotic-assisted tracheobronchoplasty in select patients. This retrospective cohort study compares postoperative complications and short-term outcomes for patients undergoing open versus robotic tracheobronchoplasty at a high-volume complex airway center.

Methods: A retrospective review of all patients who underwent open tracheobronchoplasty (2018-2020) and robotic tracheobronchoplasty (2020-2023) was conducted.

Results: During the study period, 43 and 69 patients underwent robotic and open tracheobronchoplasty, respectively. Robotic tracheobronchoplasty had longer median operative times than open (8.4 vs 6.2 hours; p = <0.01). Both median ICU length of stay (1.0 vs 3.0 days, p = <0.01) and hospital length of stay (5.0 vs 7.0 days, p = <0.01) were shorter after robotic tracheobronchoplasty. There were no significant differences in major or minor complications, total Clavien-Dindo Score, estimated blood loss, discharge to home, and 30-day readmission. The robotic group had two reoperations during the index hospitalization and three conversions to open. There were no mortalities in either group. Short-term (3-month) functional and quality of life outcomes were equivalent between groups.

Conclusions: In selected patients with severe and symptomatic excessive central airway collapse, robotic tracheobronchoplasty is a safe and feasible alternative to the traditional open approach. Patients undergoing robotic tracheobronchoplasty have shorter ICU and total hospital stays with equivalent complication rates. As the robotic approach becomes more prevalent, further comparative outcomes are necessary with longer follow-up to ensure durability of the robotic-assisted repair.
