Impact of Adjuvant Medical Therapies on Surgical Outcomes in Idiopathic Subglottic Stenosis

xlomafota13 shared this article with you from Inoreader Impact of Adjuvant Medical Therapies on Surgical Outcomes in Idiopathic Subglottic Stenosis Via The Laryngoscope Objectives/Hypothesis Adjuvant medications including proton pump inhibitors (PPI), antibiotics (trimethoprim/sulfamethoxazole [TMP-SMX]), and inhaled corticosteroids (ICS) may be prescribed for patients with idiopathic subglottic stenosis (iSGS). We describe medication use with endoscopic dilation (ED) or endoscopic resection with medical treatment (ERMT) and evaluate impact on outcomes. Study Design International, prospective, 3-year multicenter cohort study of 810 patients with untreated, newly diagnosed, or previously treated iSGS. Methods Post hoc secondary analysis of prospectively collected North American Airway Collaborative data on outcomes linked with adjuvant medication utilization. Primary outcome was time to recurrent operation, evaluated using Kaplan–Meier curves and Cox regression analysis. Secondary outcomes of change in peak expiratory flow (PEF) and clinical chronic obstructive pulmonary disease questionnaire (CCQ) score over 12 months were compared. Results Sixty-one of 129 patients undergoing ED received PPI (47%), and 10/143 patients undergoing ED received ICS (7%). TMP-SMX was used by 87/115 patients (76%) undergoing EMRT. PPI use in the ED group did not affect time to recurrence (hazard ratio [HR] = 1.00, 95% confidence interval [CI]: 0.53–1.88; P = .99) or 12-month change in PEF (L/min) (median [interquartile range], 12.0 [10.7–12.2] vs. 8.7 [−5.1 to 24.9]; P = .59), but was associated with 12-month change in CCQ (−0.05 [−0.97 to 0.75] vs. −0.50 [−1.60 to 0.20]; P = .04). ICS did not affect outcome measures. TMP-SMX use in ERMT did not affect time to recurrence (HR = 0.842, 95% CI: 0.2345–3.023; P = .79), PEF at 12 months (75 [68–89] vs. 81 [68–89]; P = .92), or 12-month change in CCQ (0.20 [−1.05 to 0.47] vs. −0.30 [−1.00 to 0.10]; P = .45). Conclusion There is no standard practice for prescribing adjuvant medications. These data do not support that adjuvant medications prolong time to recurrence or increase PEF. Patients with iSGS and gastroesophageal reflux disease may experience some symptom benefit with PPI. Level of evidence Level 3 Laryngoscope, 2021 View on the web Inoreader.
