Stent misdeployment and factors associated with failure in EUS-guided choledochoduodenostomy: an analysis of the combined datasets from the ELEMENT and DRA-MBO trials

Stent misdeployment (SMD) is a feared and poorly characterized technical challenge of endoscopic ultrasound (EUS)-guided choledochoduodenostomy (CDS) using lumen-apposing stents. We aimed to ascertain the rate of stent misdeployment in EUS-CDS for malignant distal biliary obstruction (MDBO) and describe its outcomes while identifying variables associated with its occurrence.
