title: Removal of displaced double flanged metal stent in walled-off necrosis by endoscopic ultrasonography.
abstract: Endoscopic ultrasonography (EUS)-guided walled-off necrosis drainage using a double flanged metal stent was reported for satisfactory drainage and endoscopic necrosectomy. High complication rates related to stent migration are reported. This is the first report of the removal of a displaced, double flanged metal stent in walled-off necrosis by EUS. The patient was a 62-year-old male who was suffering from mild midepigastric abdominal pain. A double flanged metal stent had been placed in our endoscopy center 8 weeks before presentation. Computed tomography demonstrated complete resolution of the walled-off necrosis; however, the stent migrated into the cyst. We dislodged the stent using forceps with real-time endosonography. In conclusion, Follow-up is important for patients with a double flanged metal stent, specifically with regards to postprocedural stent migration.
