Tracheal Resection after Previous Treatment Provides Comparable Outcome to Primary Surgery

Area of Science:

• Thoracic surgery
• Otolaryngology
• Pulmonary medicine

Background:

• Tracheal and laryngotracheal surgery offers excellent functional and long-term results for tracheal stenosis.
• Re-resections are seldom necessary due to the success of initial surgical treatments.
• This study compares outcomes of re-operation or post-bronchoscopic surgery versus primary surgical intervention.

Purpose of the Study:

• To compare the outcomes of tracheal or laryngotracheal re-resection and surgery following bronchoscopic interventions with primary surgery for benign tracheal stenosis.
• To evaluate functional results and long-term outcomes in patients undergoing different surgical pathways for tracheal stenosis.

Main Methods:

• A retrospective analysis of 66 patients undergoing tracheal resection for benign tracheal stenosis between January 2016 and April 2020.
• Patients were categorized into four groups based on prior interventions: previous resection, previous stent, previous bronchoscopic intervention without stenting, and untreated.
• Perioperative characteristics and functional outcomes were statistically analyzed.

Main Results:

• Sixty-six patients were analyzed, with varying prior interventions. Group B (previous stent) showed significantly worse lung function at baseline.
• While Group A (previous resection) required more complex reconstructions, postoperative outcomes (ICU stay, hospital stay) were comparable across groups.
• Anastomotic complications and surgical revisions were higher in the previous stent group (Group B) compared to untreated (Group D). Postoperative lung function (FEV1, PeakEF) was significantly better in the untreated group.

Conclusions:

• Tracheal or laryngotracheal resection following previous interventions can achieve outcomes comparable to primary surgery in carefully selected patients.
• Specialized centers can achieve successful results even after multiple tracheal interventions.
• The study highlights the importance of patient selection and specialized care for complex tracheal stenosis cases.
