Sequential silastic and expandable metal stenting for tracheobronchial strictures

The risks and limitations of surgical resection and reconstruction for tracheobronchial strictures demand consideration of other therapeutic options that can alleviate the distressing symptoms of tracheobronchial obstruction. One alternative is to stent the obstructive lesion until surgical advances allow primary reconstruction or replacement of the critically diseased airway or until an ideal endoprosthesis is found. The latter requires uniformity in the distribution of expansile force, conformability and stability within the tracheobronchial tree, and ease of placement. Here we report our experience with the placement of expandable metal stents (Wall-stent) used in conjunction with our Silastic (Dow Corning) endobronchial stents in 5 patients with recurrent tracheal or bronchial strictures. The major site of obstruction was the trachea in 1 patient and a main bronchus or both bronchi in 4 patients. Three patients had a benign bronchial stricture (anastomotic stricture in 2, idiopathic polychondritis in 1), and 2 patients had an obstructive airway neoplasm. Placement of the stents was performed under rigid bronchoscopic guidance. We had no complications from our technique of stenting. There has been no evidence of restenosis or occlusion within the stented segment of airway. The complementary use of expandable metal and Silastic endobronchial stents provided symptomatic and functional improvement in our patients during follow-up ranging from 5 to 24 months.
