Airway Stent Modified With 3D Printing for Gastro-respiratory Fistula Involving Carina and Distal Bronchi

Covered Metallic Segmented Airway Stent Modified With 3D Printing for Gastro-respiratory Fistula Involving Carina and Distal Bronchi

In this study, the investigators used the covered metallic segmented airway stent modified with 3D printing to treat gastro-respiratory fistula involving carina and distal bronchi and aimed to determine the feasibility, efficacy and safety of this technique.

Inclusion Criteria:

• Patients with gastro-respiratory fistula involving carina and bronchi distal to carina based on the diagnosis by bronchoscopy , gastroscopy and CT.
• The patients who could not tolerate surgery and did not have clinical improvement after conservative treatment.

Exclusion Criteria:

• Severe infection
• coagulation disorders
