Management of non-tumoral tracheal stenosis in 112 patients

From January 1973 to August 1989, 112 patients with non-tumoral tracheal strictures were treated in our unit. In 102 patients, the stenosis followed respiratory support. Eighty-one patients were treated surgically; the rest required only endoscopic therapy. In 28 patients, surgical treatment followed failure of endoscopic management. Of the patients submitted to surgery an isolated tracheal stenosis was present in 54 cases while a laryngotracheal stricture was the lesion in the other 27. Tracheal resection and end-to-end anastomosis was performed in the former group. Rethi, Pearson and Couraud procedures, respectively, were carried out in the latter. We emphasize the difference in the results achieved in the first 5 years and those obtained in the last 10 years. In the former period, 7 reoperations were needed. On the other hand, although the overall mortality of both series was 9%, it decreased to 2% during the last 10 years. Excellent or good ultimate results were achieved in 92% of survivors. Finally, we stress the differences in the proportion of reinterventions and definitive failures in the surgical treatment of isolated tracheal stenosis compared to laryngotracheal strictures.
