Abstract
Background Tracheal stenosis is able to lead to airway obstruction. Objective To evaluate the efficacy and safety profile of Montgomery T-tube implantation in patients with tracheal stenosis. Methods Fifty-two patients with tracheal stenosis diagnosed between 2016 and 2019 were included in this retrospective cohort study. The patients were divided into observation group (n = 25 cases) and control group (n = 27). The therapeutic effect, arterial blood gas analysis, arterial oxygen partial pressure (PaO2), arterial carbon dioxide partial pressure (PaCO2), shortness of breath score, airway diameter change, dyspnea score, quality of life, and safety were compared between the two groups before and after treatment. Results The therapeutic effect of the observation group gained better results than that of the control group (84.00% vs. 62.96%). One week after operation, the pH value, SaO2, PaCO2, shortness of breath score, airway diameter change, dyspnea score, life quality, and incidence of postoperative complications in the observation group exerted better results as compared to the control group. Conclusion The implantation of Montgomery T-tube has effective function in terms of improving the symptoms of dyspnea and the life quality of patients with safety profile in patients harboring tracheal stenosis.
Highlights
Tracheal stenosis is able to lead to airway obstruction, causing shortness of breath and dyspnea, which is aggravated by increased respiratory secretions, physical activity, or aerobic exercise, accompanied by wheezing and can result in asphyxia in serious cases [1, 2]
For some patients with tracheal stenosis, lesions may not be completely removed, and improper suture at the end of the operation will lead to restenosis of the tracheal scar. e degree and length of stenosis affect the choice of operation
If the inner segment of the Montgomery T-tube cannot be completely dilated, the balloon-assisted Montgomery T-tube should be used to open the inner segment of the Montgomery T-type stent. e results of this study showed that one week after operation, the score of shortness of breath, the change of airway diameter, the score of dyspnea, and the quality of life in the observation group were better than those in the control group (P < 0.05), indicating that the implantation of Montgomery T-tube in patients with tracheal stenosis can effectively improve the outcomes of patients with shortness of breath and dilate the airway diameter, which is beneficial to breathing and improves the quality of life of patients
