Summary

This study demonstrates that expandable esophageal stents can be safely and effectively placed using only endoscopic visualization, eliminating the need for fluoroscopy. This technique improves swallowing function in patients with esophageal cancer.

Area of Science:

  • Gastroenterology
  • Oncology
  • Medical Devices

Background:

  • Limited access to fluoroscopic equipment in esophageal cancer prevalent regions.
  • Esophageal cancer frequently causes dysphagia, necessitating palliative interventions.
  • Development of alternative stent placement methods is crucial for underserved areas.

Purpose of the Study:

  • To describe a simplified method for expandable esophageal stent placement.
  • To evaluate the efficacy and safety of stent placement without fluoroscopy.
  • To assess the impact of this technique on dysphagia scores.

Main Methods:

  • Esophageal stent placement performed solely under direct endoscopic control.
  • Utilized a colored mark on the delivery catheter for precise stent positioning.

  • Included 70 patients with dysphagia due to unresectable esophageal cancer.

    • Main Results:

    • Successful stent placement in all 70 patients.
    • No immediate complications reported post-procedure.
    • Significant reduction in mean dysphagia score from 3.3 to 0.5.
    • A trend towards better outcomes with coated stents was observed.

    Conclusions:

    • Direct endoscopic visualization is sufficient for accurate and safe esophageal stent placement.
    • Fluoroscopy is not required for this procedure.
    • This method offers a viable alternative in resource-limited settings.
