title: Use of endotracheal silicone stents for relief of tracheobronchial obstruction.
abstract: In this article we describe our initial experience with bifurcated and longitudinal silicone stents that can be inserted entirely endoscopically. A total of 10 patients were stented; half had upper airways obstruction resulting from malignant disease and half had anastomotic obstruction after single-lung (3 patients), double-lung (1 patient), or heart-lung transplantation (1 patient). All patients derived immediate relief of life-threatening stridor. Stents were in place for between 5 days and 2 1/2 years (mean, 232.9 days). In the patients with malignant disease, the stents have provided effective relief from stridor for the remainder of their lives. In the transplant recipients, the medium-term results are encouraging, with the stents providing effective relief from stridor, although the longitudinal stents have been associated with distal migration, requiring that the stents be replaced on up to five occasions. The stents have not been associated with infection in the nonimmunosuppressed patients, and during the relatively short follow-up period there has been no tissue reaction to the material.
