Core Tip
Core tip: Migration of self-expandable esophageal stents occurs in up to 36% of cases. The lasso system available in most stents provides a safe way to remove or reposition the stent while it is still in the esophagus. However, when the stent migrates into the stomach, other techniques are needed to guarantee a safer retrieval. The use of clipping, suturing or external fixation should be considered for stents at high risk for migration.
