Multidisciplinary approach to management of postintubation tracheal stenoses.

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.
