ROCABADO B, JOSÉ LUIS et al. Management of tracheal stenosis. Rev Chil Cir [online]. 2007, vol.59, n.6, pp. 408-416. ISSN 0718-4026. doi: 10.4067/S0718-40262007000600004.
Background: Tracheal stenosis is a common complication of intubation or tracheostomy. Aim: To report the experience with tracheal stenosis and propose a new classification to standardize its management. Material and Methods: Prospective study of 32 patients aged 17 to 79 years, 23 males. Twenty had a benign and 12 a malignant stenosis, four of which had tracheoesophageal fistula. Seven patients had a Type I stenosis, defined as a lesion of less than 1 cm in length, five had a type II lesion, defined as a diffuse lesion of less than 3 cm in length and 20 cases had a type III lesion defined as a stenosis of more than 3 cm, in length or multiple lesions or tracheomalacia. Patients with type I stenosis were treated with electro coagulation, those with type II lesions were subjected to a primary resection and tracheal end-to-end anastomosis and type III patients were treated using a dynamic stent. Results: Evolution after treatment was favorable with disappearance of clinical manifestations, improvement in functional capacity and modified Borg Scale score in 69% of the patients. Life quality and flow-volume curves improved in 100% of patients. Seven patients died due to progression of cancer and one committed suicide. Conclusions: The classification of tracheal stenosis in three types, depending on the morphology and extent of the lesion allows a better planning of treatment
