Abstract

EUS-guided drainage of unresectable malignant common bile duct strictures (CBD) after failed ERCP and of the gallbladder (GB) in patients with acute cholecystitis unfit for surgery are alternative minimally invasive treatment modalities to percutaneous drainage. Up to now, available EUS-techniques to perform these procedures have required frequent accessories exchange with risk of dislocation and therefore of bile leak and perforation. Our aim was to investigate one-step fluoroless EUS-guided CBD and GB drainage by using a novel lumen-apposing, self-expanding fully covered metal stent incorporated in an electrocautery enhanced delivery system that allows direct puncture of a target, insertion and release in a one-step-fashion.
