Tratamiento de la estenosis traqueo-bronquial con prótesis. Factores de buena respuesta.

Aim : Determine good response predictors in use of stent in benign and malignant tracheobronchial stenosis. Materials and Methods : We retrospectively reviewed medical records of patients submitted to the procedure in the period 2014 to 2016. Clinical records, operative protocols, and histopathological and imaging studies were reviewed. Demographic and clinical data, performance status (PS) at admission and after the procedure, etiology of tracheal stenosis, need for oxygen in liters (L) Post-intervention, hospital stay, procedure-related morbidity, indication of therapy (Chemotherapy and/or Radiotherapy) and survival. Data were analyzed with descriptive and analytics statistics. Results : A total of 68 procedures were performed in 44 patients, 24 women. Tracheal stenosis 40 cases were diagnosed. The malignant etiology was 88%. The admission PS was greater than or equal to 2 in 68% and 22% after the procedure. The oxygen requirements prior to the procedure were at least 1 L in 36 cases and decreased in 13 cases after the procedure. The average hospitalization period was 6.2 days (1-60). Complementary therapy was indicated in 13 patients; the morbidity associated with the procedure was 2.9%, displaced installation and iatrogenic injury. The one year survival was 27%. Conclusions : Benign etiology, el PS minor than or equal to 3, oxygen requirements prior to the procedure of 1 L and tumoral obstruction less than 75% were good response predictors in our study.
