[Therapeutic effect of tracheal anastomosis versus interventional bronchoscopy in the treatment of airway stenosis].

Objective: To compare the therapeutic effects of tracheal anastomosis and interventional bronchoscopy in the treatment of airway stenosis.

Methods: From February, 1990 to February 2008, 53 patients with airway stenosis including 32 male and 21 female patients aged 2 to 80 years (mean 38 years) received end-to-end anastomosis or bronchoscopic stent-graft treatment in our hospital. End-to-end anastomosis of the narrow sleeves resected was performed in 26 cases, balloon dilatation in 14 cases, and stent implantation in 13 cases. The clinical and follow-up data of the patients were analyzed retrospectively and the surgical outcomes were evaluated.

Results: No perioperative deaths occurred in these cases. Eight patients (5 with anastomosis, 2 with balloon dilation, and 1 with stent implantation) were lost to the follow-up ranging from 1 to 204 (mean 44.94-/+54.56) months. Of the patients available to the follow-up, 12 had airway restenosis, including 2 receiving end-to-end anastomosis (9.5%), 6 (50%) receiving balloon angioplasty, and 6 with granulation hyperplasia following stent implantation (50%). Of the 3 treatment, end-to-end anastomosis was associated with the lowest restenosis rate (Chi2=8.869, P=0.012).

Conclusion: End-to-end anastomosis, with a low postoperative restenosis rate and better prognosis, should be the primary choice for treatment of tracheal airway stenosis.
