Endoscopic Ultrasound and Endoscopic Retrograde Cholangiopancreatography for Malignant Distal Biliary Obstruction

EUS-BD is a minimally invasive technique where the common bile duct (choledochoduodenostomy) is punctured under EUS-guidance and after transmural dilation, a stent is deployed for biliary drainage.

During the ERCP, a small catheter and guidewire is inserted into the bile duct and the stent can be deployed into the duct.
