Benign Tracheobronchial Stenoses: Long-term Clinical Experience with Balloon Dilation
Section snippets
Patients
From November 1994 to September 2000, 59 consecutive patients (45 women and 14 men; age range, 1–76 y; mean age, 36 y) were treated by means of fluoroscopically guided balloon dilation. These patients were followed for at least 12 months and the results were evaluated retrospectively. Indications for balloon dilation included clinical respiratory symptoms (eg, dyspnea, cough, stridor, wheeze, or recurrent postobstructive pneumonia), decline of pulmonary function test (PFT) results, and stenosis
Initial Improvement
A total of 101 balloon dilation sessions were performed in 59 patients, with a range of one to four sessions per patient (mean, 1.7 sessions). Balloon dilation was performed in a single session in 35 patients, two sessions in 10 patients, three sessions in 10 patients, and four sessions in four patients. There were no technical failures. Clinical success was achieved in 49 (83%) of the 59 patients (Fig 1). These patients described a subjective improvement of physical well-being and ease of
DISCUSSION
Since the first report of balloon dilation to treat tracheobronchial stenosis by Cohen et al (3) in 1984, several reports have described the usefulness of balloon dilation in the treatment of airway stenosis. Short-term results of balloon dilation to treat benign tracheobronchial stenosis have been favorable (9, 10, 11). However, the longterm efficacy of balloon dilation in a large number of patients has rarely been reported. Carre et al (11) reported a 100% clinical success rate and 50%

Lee and colleagues15 reported the incidence of bronchospasm as less than 1% during bronchoscopic airway dilation. Manifestations include coughing, dyspnea or desaturation if pulse oximetry is monitored.
