Abstract:
Okuaki and colleagues present a case video of a stent-stone complex formed by the anti-migration system of a self-expandable metallic stent used in endoscopic ultrasound-guided biliary drainage. As the stone caused gastric outlet obstruction, they successfully crushed it using a balloon catheter and electronic hydraulic lithotripsy with a two-channel scope.
