Abstract
As many as 8% of self-expanding esophageal metal stents (SEMS) migrate, especially the covered types. Most often this occurs within 1 month of placement.1 They can move through the pylorus and induce obstruction, bleeding, or perforation.2 Thus it is necessary that migrated stents be extracted. Different extraction methods have been proposed, all of which are technically challenging. The major cause of failure is the high expansion force of SEMS which hampers the ability to compress the stent to a size small enough to allow it to be removed.
