Efficacy of the double inverted Y-shaped airway covered stent therapy thoracostomach-right main bronchus fistula / 实用放射学杂志

ABSTRACT

Objective To study the efficacy of double inverted Y-shaped airway covered stent for patients with thoracostomach-right main bronchus fistula.Methods Fifteen cases with thoracostomach-right main bronchus fistula were investigated retrospectively.All patients had accepted esophageal resection and thoracostomach esophagus anastomosis,as well as radiation therapy after surgery due to esophageal cancer. All fistulas located close to the opening of right upper lobe bronchus.According to the normal tracheobronchial diameter and length of patients,two inverted Y-shaped airway covered stents were designed individually.Stenting was performed under X-ray,and the situation of fistula and clinical symptoms improvement were investigated.Results The double inverted Y-shaped airway covered stents were implanted and fistulas were closed successfully.All patients could take normal diet,and the supine cough symptoms disappeared, without complications such as airway bleeding and pneumothorax after stenting.Conclusion The stenting of double inverted Y-shaped airway covered stent may be an effective,feasible and safe treatment for thoracostomach-right main bronchus fistula.
