[Temporary endoscopic occlusion of tracheoesophageal fistula prior to radical surgery]

To assess the effectiveness of Amplatzer Septal Occluder as a palliative approach for temporary TEF occlusion before radical surgery.

The authors present a patient with multifocal post-tracheostomy TEF after mechanical ventilation for COVID-19. Two Amplatzer Septal Occluders were implanted under endoscopic guidance for temporary occlusion. Effectiveness, recurrence rate, and feasibility of radical surgery were evaluated.

TEF occlusion successfully eliminated aspiration and enabled radical repair after four months with minimal postoperative complications. However, device dislocation and fistula enlargement were identified as limitations.

This method appears promising but requires further research to assess complication risks and optimize implantation techniques.
