Reconstrucción de estenosis traqueal benigna: experiencia de un hospital de alta complejidad en Colombia

Introduction. The most common cause of benign laryngotracheal stenosis is iatrogenic, secondary to orotracheal intubation. Surgical management continues to be the alternative that has shown better long-term results. The objective of this study was to analyze the experience in the surgical management of laryngotracheal stenosis for 15 years in a high-level complexity hospital in Colombia. Methods. Medical records of patients treated with reconstruction of benign tracheal stenosis between 2005 and 2020 were reviewed. Descriptive statistical methods were used, with frequency analysis and measures of central tendency or dispersion. Results. Thirthy-eight patients with laryngotracheal stenosis were identified, with a variable degree of stenosis. Nasofibrolaryngoscopy was well tolerated and safe to determine the degree and length of the stenosis. The use of tomography served to determine the extension and anatomical characteristics. The results of the present study are similar to those of the literature in terms of complications, mortality and failure of the anastomosis. The most frequently reported complications are restenosis, surgical site infection, nerve injury, and fistula, which generally occur in one third of patients. Conclusions. The experience of surgical management of laryngotracheal stenosis in our hospital allows us to conclude that tracheal reconstruction is a safe option in our environment. Treatment success and failure rates are comparable to those reported in the literature.
