Percutaneous Approach for Removal of a Migrated Cystogastric Stent from a Pancreatic Pseudocyst: A Case Report and Review of the Literature

Abstract

Stent migration into pancreatic pseudocysts during endosonographic (EUS) cystogastrostomy is a relatively rare complication. The migrated stent may induce, if it remains within the body, infection and perforation. Therefore, retrieval and/or re-stenting is necessary. Endoscopic retrieval is commonly attempted first. However, it is technically challenging and largely dependent on the skill of the endoscopists; if retrieval is unsuccessful, surgery is usually carried out. We report a case of stent migration into a pancreatic pseudocyst that was retrieved with a percutaneous approach under imaging guidance using a simple technique with available devices. A technique that enhances the role of interventional radiology in the management of this rare complication.
