Removal of a Covered Esophageal Stent which Migrated into the Stomach Lumen, Using Fiberscope and Snares

Abstract

We successfully endoscopically removed an esophageal stent that had migrated into the stomach. A 63-year-old man was given a diagnosis of advanced esophageal cancer 7 cm long in the Ut-Ce region. A covered self-expanding type metallic stent was inserted. After that we continued chemotherapy on an outpatient basis, but 100 days later after placement of the stent, it migrated to the stomach. We replaced it with an uncovered self-expanding type metallic sent, then using a 2-channeled fiberscope, brought up the narrow drop stent from the stomach. Next we secured the migrated stent by two forceps into the replaced stent under fluorescence endoscopy. We successfully removed the migrated stent from the stomach, and did not remove the newly inserted stent. Removal of a stent that has migrated into the gastric lumen using a fiberscope and snares is rare.
