Resumen

Realizamos un estudio retrospectivo de veinte casos de estenosis traqueal pura por intubación endotraqueal, diagnosticados y tratados en nuestro centro entre 1995 y 1999. De los veinte pacientes estudiados 17 eran hombres (85%) y tres (15%) eran mujeres, con edades comprendidas entre 9 y 68 años (32,8 ± 14,9 años). La extensión del segmento estenosado varió entre los 2 y 5 cm (3,3 ± 1,2 cm). Todos estos casos fueron tratados quirúrgicamente por vía externa para resección del segmento estenosado y posterior anastomosis traqueo- traqueal. Los resultados clínicos evaluados entre el tercer y sexto mes postoperatorio fueron: 16 casos (80%) con buen resultado, dos casos (10%) con resultado satisfactorio y dos resultados insatisfactorios (10%), verificando que la existencia de una estenosis, para un nivel de confianza del 5%, está relacionada con el tiempo de intubación y la edad del paciente (R=0,478, p= 0,033).

Abstract

The authors report a case review series of 20 patients with tracheal stenosis after prolonged oral or nasotracheal intubation who underwent surgical treatment between 1995 and 1999. Seventeen were male (85%) and three (15%) were female. The age varied between 9 and 68 years (32,8 ± 14,9 years). The stenotic area of the airway was limited to the trachea, and its length varied between 2 and 5 cm (3,3 ± 1,2 cm.). All patients were treated surgically with an external approach for reconstruction after stenosis ablation. Follow up was at three and six months after surgery there were: 16 cases with (80%) good results, two (10%) with satisfactory results and two unsatisfactory (10%). We found a statistically significant correlation (Spearman correlation) of 5% level between the period of tracheal intubation and patient’s age (R= 0,478, p= 0,033).
