Idiopathic Subglottic and Tracheal Stenosis: A Survey of the Patient Experience.

OBJECTIVES: To report and compare patients' experiences with acquired subglottic stenosis (AS) versus idiopathic subglottic and tracheal stenosis (ISTS). METHODS: A survey was made available to patients with AS and ISTS. Results were analyzed for inter- and intragroup differences using a 2-tailed t test. RESULTS: The study included 160 survey participants (AS n = 28; ISTS n = 132), with a predominance of female participants (82% AS, 98% ISTS). Acid reflux was the most prevalent comorbidity across groups (42%-43%). A significant difference in time to diagnosis was found between groups, with 32% of AS patients diagnosed within 3 months of symptom onset, compared to 2% with ISTS. A diagnosis delay greater than 18 months occurred for 58% of ISTS patients. There was no difference in treatment approach, with the most common treatment being balloon dilation, followed by laser dilation. Tracheal resection was performed in 36% of patients in both groups. Patient satisfaction with surgical outcomes was significantly higher after tracheal resection (76%) compared to other treatment modalities (39%). CONCLUSIONS: ISTS remains a diagnostic challenge as highlighted by the delay in diagnosis compared to AS. There appears to be no historical or symptomatic factors specific to ISTS. Additionally, patients report increased satisfaction and symptom resolution after tracheal resection.

[Etiology, prophylaxis and treatment of extensive, multifocal cicatricial tracheal stenosis at the junction of sciences--surgery and anesthesia].

759 patients with cucatritial stenosis of trachea were treated in the Russian Scientific Center of Surgery in the period from 1963 to 2009. Extensive or multifocal stenosis was diagnosed in 172 patients. 157 patients were previously operated in other hospitals. The lesion of larynx during admission was diagnosed in 122 cases. All patients were operated in compliance with the principle of alternation methods of anesthesia and respiratory support. As a result of consistent application of the landmark reconstructive-plastic operations and resection in combination with endoscopic surgery good results were achieved. Based on the data, treatment algorithm of extended and multifocal cicatricial stenosis of the trachea was developed.

The impact of social determinants of health on laryngotracheal stenosis development and outcomes.

OBJECTIVES: The social determinants of health affect a wide range of health outcomes and risks. To date, there have been no studies evaluating the impact of social determinants of health on laryngotracheal stenosis (LTS). We sought to describe the social determinants in a cohort of LTS patients and explore their association with treatment outcome. METHODS: Subjects diagnosed with LTS undergoing surgical procedures between 2013 and 2018 were identified. Matched controls were identified from intensive care unit (ICU) patients who underwent intubation for greater than 24 hours. Medical comorbidities, stenosis characteristics, and patient demographics were abstracted from the clinical record. Tracheostomy at last follow-up was recorded from the medical record and phone calls. Socioeconomic data was obtained from the American Community Survey. RESULTS: One hundred twenty-two cases met inclusion criteria. Cases had significantly lower education compared to Tennessee (P = .009) but similar education rates as ICU controls. Cases had significantly higher body mass index (odds ratio [OR]: 1.04, P = .035), duration of intubation (OR: 1.21, P < .001), and tobacco use (OR: 1.21, P = .006) in adjusted analysis when compared to controls. Tracheostomy dependence within the case cohort was significantly associated with public insurance (OR: 1.33, P = .016) and chronic obstructive pulmonary disease (OR: 1.34, P = .018) in adjusted analysis. CONCLUSION: Intubation practices, medical comorbidities and social determinants of health may influence the development of LTS and tracheostomy dependence after treatment. Identification of at-risk populations in ICUs may allow for prevention of tracheostomy dependence through the use of early tracheostomy and specialized follow-up.

Validation of the Clinical COPD Questionnaire as a psychophysical outcome measure in adult laryngotracheal stenosis.

OBJECTIVES: To validate the Clinical Chronic Obstructive Pulmonary Disease Questionnaire (CCQ), a patient-administered instrument developed for bronchopulmonary disease as a disease-specific psychophysical outcome measure for adult laryngotracheal stenosis. DESIGN: Prospective observational study. SETTINGS: Tertiary/National referral airway reconstruction centre. PARTICIPANTS: Thirty-three tracheostomy-free patients undergoing endoscopic laryngotracheoplasty. MAIN OUTCOME MEASURES: CCQ and the Medical Research Council (MRC) Dyspnoea scale, a previously validated but more limited scale, were administered to patients 2 weeks before surgery, preoperatively, and 2 weeks after endoscopic laryngotracheoplasty. Pulmonary function was assessed preoperatively. Internal consistency was assessed with Cronbach alpha statistics and test-retest reliability was determined using intraclass correlation. Correlations between CCQ and MRC scale, and pulmonary function were used to assess convergent and divergent validity respectively. Instrument responsiveness was assessed by correlating total and domain-specific CCQ scores with anatomical disease severity and post-treatment effect size. RESULTS: There were 12 males and 21 females. Mean age was 44 +/- 15 years. Cronbach alpha coefficient and intraclass correlation coefficient were 0.88 and 0.95 respectively. Total and domain-specific CCQ scores significantly correlated with the MRC scores (P < 0.001) and significant correlations between CCQ and peak expiratory flow rate and FEV(1) were identified (P < 0.03). There were statistically significant changes in total and domain-specific CCQ scores when different stenosis severities were compared. Clinical COPD Questionnaire scores also changed significantly and congruently following surgery (P < 0.05 in both cases). DISCUSSION: Clinical COPD Questionnaire is a valid and sensitive instrument for assessing symptom severity and levels of function and well-being in adult patients with laryngotracheal stenosis and can be used as a patient-centred disease-specific outcome measure for this condition.
