Stenting of strictures close to the upper esophageal sphincter with the Polyflex stent

Abstract

Stent insertion in strictures in the upper cervical esophagus present special difficulties, such as patient discomfort and worry due to continuous neck globus sensation and a metallic taste. Additionally, the endoscopist needs to have great skill to properly adjust the proximal stent end. We present the experience of stenting high cervical esophageal strictures with a self-expanding plastic stent (Polyflex), in three tumoral and one postoperative benign stenosis. Dysphagia disappeared and the endoprosthesis was well tolerated. The Polyflex stent seems to be suitable for insertion in the upper esophagus.
