Operative findings of the migrated stent into the abdominal cavity following endoscopic ultrasound-guided hepaticogastrostomy: Anchoring force of a novel self-expandable metal stent with an anti-migration system (with video).

Koga et al report an emergency surgery for stent migration during endoscopic ultrasound-guided hepaticogastrostomy, which revealed the strong anchoring force of a stent with a spring-type stopper as an anti-migration system at the proximal end. The stent could not be pulled out of the stomach wall and was removed via gastrotomy.
