Endoscopic ultrasound‐guided choledochoduodenostomy using a thin stent delivery system in patients with unresectable malignant distal biliary obstruction: A prospective multicenter study

When endoscopic retrograde cholangiopancreatography (ERCP) fails in patients with malignant distal biliary obstruction, endoscopic ultrasound‐guided choledochoduodenostomy (EUS‐CDS) is an alternative. It has high technical and clinical success rates, but also has high adverse event rates. This prospective cohort study was aimed to evaluate the clinical efficacy and safety of EUS‐CDS with our newly developed partially covered self‐expandable metal stent with a thin delivery system.
