Abstract: Objective: Evaluate the efficacy and safety of double stents (bare metal stent and covered metal stent) for esophagorespiratory fistulas (ERFs). Methods Clinical data from 10 patients receiving double stents treatment were retrospectively reviewed. Results A total of ten ERFs in 10 patients were included. The fistulas, all caused by lung cancers, had diameters of 0.5 to 5.0 cm. Double stents were successfully placed. Fistula was completely sealed in 70% of patients and other 30% patients showed a partial response. The total efficacy rate was 100%. Conclusion A bare metal stent followed by a covered metal stent( double stents), appears to be a safe and feasible regime for ERFs.
