A new designed self-expandable metal stent for the management of benign radiotherapy-induced hypopharyngeal or cervical esophageal strictures.

The use of this conformable, small caliber new designed Niti-S stent, exchanged periodically, appeared safe and permitted durable oral intake in patients with difficult-to-treat hypopharyngeal or cervical esophagus strictures, avoiding the need for periodic dilations.
