A simplified strategy for stent fixation using a defect-closure system in refractory esophageal stricture
Poster Abstract

Abstract Text

Refractory benign esophageal strictures are commonly treated with fully covered stents, but migration occurs in up to 40% of cases. Endoscopic fixation methods have been introduced to resolve this issue. The X-Tack system, originally designed for GI defect closure, has been repurposed for stent anchoring. We report a simplified tack-only fixation approach that omits the suture component to streamline deployment. A 19-year-old patient with severe caustic-induced stricture, refractory to repeat dilations, experienced early migration of an initial stent. A second fully covered stent was placed and individually secured along the proximal stent edge using sequential helical tacks deployed through the stent mesh into healthy esophageal tissue. At 4-week follow-up, stent removal showed marked luminal improvement. This suture-less tack-only method appears feasible and reproducible.
