Esophageal stent migration: A report of two cases

Self-Expandable Metallic Stents (SEMSs) are widely used to treat esophageal strictures, both benign and malignant in origin. Esophageal stenting, performed by using different types of SEMS (fully covered, partially covered or uncovered), has a high technical success rate, but carries the risk of several complications occurrence, including migration that is considered one of the major. We report two cases of fully coated (FC) SEMS displacement and discuss migration predisposing factors, aiming to highlight the differences in safety of partially coated (PC) versus FC-SEMSs in malignant stenosis.
