Modified Type of Double-Covered Self-Expandable Segmental Metallic Stents for Palliation of Esophageal Fistula

摘要

Purpose: To study the modified type of double-covered self-expandable segmental metallic stents in terms of efficacy, complications, and long-term outcomes. Patients and Methods: A retrospective review of a consecutive series of 24 patients who underwent placement of the modified stent from July 2013 to July 2018 was conducted. Twenty-five modified segmental stents were implanted. Data regarding technical success and complications were collected and analyzed. Results: Stent placement was successful in all patients with no perioperative procedure-related deaths. The median follow-up time was 10.3 months (interquartile range 6.3-23.5 months). Adjustment was required in 9 patients (37.5%) due to stent migration. The mean dysphagia scores before stenting and during follow-up were 3.6 +/- 0.7 and 0.9 +/- 1.6, respectively (P < .0001). Fifteen modified stents were removed due to complications or cure. Conclusion: Modified double-covered self-expandable segmental metallic stents are safe and effective for palliation of esophageal fistula.
