Inoperable tracheobronchial stenoses are most often due to malignant disease. Apart from systemic therapy, various local treatment modalities such as laser resection, cryotherapy and endobronchial radiation therapy have been designed to maintain airway patency. Recently, various models of tracheobronchial stents (or endoprostheses) have been designed to maintain airway patency. They prevent recurring endobronchial tumor growth or progressive extrinsic compression of dilated airways. Silicone stents are highly suitable for this purpose. We treated 12 patients (11 males, 1 female, median age 68,5 years) suffering from bronchial carcinoma (6), esophageal carcinoma (4), metastatic colon carcinoma (1) and metastatic osteosarcoma (1). One stent per patient was inserted at the following sites: 6 in the right main bronchus, 4 in the trachea, 1 in the left main bronchus and 1 tracheobronchial left. We observed 2 complications: one obstruction of a bronchial stent by secretions which could be managed by fiberbronchoscopy and one short fire to a bronchial stent on repeat laser therapy. Rapid and lasting relief of dyspnea was observed in all patients. Our initial experience with a median follow-up of 2 months confirmed the easy insertion technique, the excellent effect and tolerance as well as the simple postoperative care of these silicone stents. Their use immediately after relief of a tracheobronchial obstruction by local means can be recommended.
