Self-expanding covered metallic stent treatment of esophagojejunostomy fistulas

Purpose

The purpose of this study is to analyze the outcomes of the self-expanding covered metallic stent (SECMS) therapy in the management of the postoperative anastomotic leaks that seen after total gastrectomy–esophagojejunostomy (EJ) operations.

Materials and methods

Contrast radiography and endoscopy revealed EJ fistulas in 14 patients. SECMSs were implanted both fluoroscopically and endoscopically to seal fistulas. Postoperative fistula diagnosis times, postoperative covered stent implantation times, primary success rates, clinical success rates, postinterventional oral feeding beginning times, reduction of the drainage from the surgical drains, procedure-related mortality–morbidity, and mortality related with factors other than the procedure were noted.

Results

Technical success rate was 100 %. Clinical success rate was 79 %. Reduction of the fluid from surgical drains was observed in all patients. There were no procedure-related mortality. Recurrent fistula was observed in two patients (14 %) at the third and fifth day after the intervention. In one patient (7 %), stent dislocation was observed at the 10th day after the intervention. Non procedure-related mortality was 21 %. No anastomotic stricture, no in-stent stenosis was observed during the follow up period(11.09 ± 3.21 months).

Conclusion

From the above results we concluded that SECMS treatment for EJ fistulas is a safe, effective and technically easy procedure.
