Abstract
Placement of self-expandable metal stents (SEMS) provides effective palliation in patients with malignant dysphagia. Although fully covered SEMS are increasingly used to prevent tissue ingrowth, they are prone to migrate. To reduce migration risk, we developed the HANARO-Utrecht stent, a new fully covered 20-mm SEMS which combines bilateral flared ends and three rows of anchoring flaps on the stent body for the prevention of migration.
