The optimal management of postintubation tracheal stenosis is not well defined.A therapeutic algorithm was designed by thoracic surgeons, ear, nose and throat (ENT) surgeons, anaesthetists and pulmonologists. Rigid bronchoscopy with neodymium±yttrium aluminium garnet (Nd-YAG) laser resection or stent implantation (removable stent) was proposed as first-line treatment, depending on the type of stenosis (web-like versus complex stenosis). In patients with web-like stenoses, sleeve resection was proposed when laser treatment (up to three sessions) failed. In patients with complex stenoses, operability was assessed 6 months after stent implantation. If the patient was judged operable, the stent was removed and the patient underwent surgery if the stenosis recurred.This algorithm was validated prospectively in a series of 32 consecutive patients. Three patients died from severe coexistent illness shortly after the first bronchoscopy. Of the 15 patients with web-like stenosis, laser resection was curative in 10 (66%). Among the 17 patients with complex stenoses, three remained symptom-free after stent removal. Bronchoscopy alone was thus curative in more than one-third of the patients. Six patients underwent surgery, two after failure of laser resection and four after failure of temporary stenting. Surgery was always performed with the patient in good operative condition. Palliative stenting was the definitive treatment in nine cases. Tracheostomy was the definitive solution in two cases.This approach, including an initial conservative treatment, depending on the type of the stenosis, appears to be applicable to almost all patients and allows secondary surgery to be performed with the patient in good condition.

The outcome of asthma and/or nonspecific bronchial hyperresponsiveness (BHR) associated with nasal polyposis (NP) is uncertain. Over a 4-yr period, we investigated the long-term changes of pulmonary function and BHR in 46 patients with NP. Each subject was assessed for nasal symptoms and tested for allergy skin prick tests, serum total IgE, spirometry, and carbachol challenge at baseline before initiating any treatment (T0). Nasal symptoms evaluation, spirometric measurements, and carbachol challenge were repeated at T1 and at T2 (respectively, 12.7 +/- 0.9 and 47.9 +/- 2. 2 mo after T0). In addition, bronchodilator response was measured at T2. At T0, 25 patients exhibited BHR and 16 of 25 were asthmatic. All patients were treated first with topical steroids for 6 wk (beclomethasone 600 microg/d). Eighteen patients were successfully treated with topical steroids (topical steroids responders). Intranasal ethmoidectomy was performed in 28 patients who did not improve with topical steroids alone (topical steroids nonresponders). Nasal score improved at T1 and remained improved at T2 as compared with T0 in both groups (p < 0.005). Topical steroids nonresponders demonstrated a significant decrease of FEV(1), FEV(1)/FVC ratio, and FEF(25-75) at T1 (p < 0.05) and at T2 (p < 0.0005), whereas no significant change was observed in FEV(1) and FEV(1)/FVC ratio in responders. DeltaFEV(1) (%) between T2 and T0 was not related to the presence of asthma, BHR, or atopy. Bronchodilator response at T2 was similar in the two groups. BHR did not significantly change over the 4-yr follow-up period in the two groups. No change in pulmonary symptoms and/or asthma severity occurred. Our results show that nonreversible airflow obstruction appears over a 4-yr follow-up period in topical steroids nonresponders patients with NP requiring nasal surgery. The long-term contribution of these changes to the development of respiratory symptoms in patients with NP remains to be documented.
