Abstract

Abstract: Objective: Although tracheal stomal stenosis can be life-threatening, factors associated with the occurrence of stomal stenosis remain unknown. This study was performed to evaluate these factors in adult patients. Methods: We retrospectively identified adult patients who underwent tracheostomy from 2010 to 2016 using a Japanese national inpatient and outpatient database. We performed Cox proportional hazard regression analyses to evaluate factors associated with the occurrence of tracheal stomal stenosis. Results: We obtained data on 25, 436 eligible patients. The proportion of tracheal stomal stenosis was 0.9%. Tracheal stomal stenosis was significantly less likely to occur in patients with regular use of oral steroids [hazard ratio (HR), 0.28; 95% confidence interval (CI), 0.09–0.88; P = 0.03] and in male patients (HR, 0.75; 95% CI, 0.57–0.97; P = 0.03). The occurrence of tracheal stomal stenosis was significantly associated with use of a mechanical ventilator at home (HR, 2.54; 95% CI, 1.55–4.15; P < 0.001) and a body mass index of <18.5 kg/m 2 (HR, 1.45; 95% CI, 1.06–1.99; P = 0.02). Conclusion: Our study revealed several factors that are associated with tracheal stomal stenosis. These findings may help physicians to manage tracheal stomas.
