Technical feasibility and safety of a new, implantable reflux control system to prevent gastroesophageal reflux in patients with stents placed through the lower esophageal sphincter (with video).

Abstract

When an esophageal stent is placed through the lower esophageal sphincter (LES), gastroesophageal reflux symptoms may persist despite high-dose proton pump inhibitor therapy. A recently developed, short segment, uncovered nitinol stent with a tricuspid-like valve can be placed inside a previously placed esophageal stent.
