Removal of a partially covered stent by endoscopic substent dissection

Herein we describe a new technical endoscopic removal of embedded partially covered esophageal stent that was inserted to treat a iatrogenic perforation of esophagus. Usually, partially covered stents can be removed by the stent-in-stent technique. In this case, the embedded stent could not be removed safely with this technique; so we performed a sub stent dissection to detach the stent from the esophageal wall
