title: Endoscopic Ultrasound-Assisted Pancreaticobiliary Access.
abstract: Endoscopic retrograde cholangiopancreatography (ERCP) is the primary approach to drain an obstructed pancreatic or biliary duct. Failed biliary drainage is traditionally referred for percutaneous transhepatic biliary drainage or surgical bypass, which carry significantly higher morbidity and mortality rates compared with ERCP and transpapillary drainage. Endoscopic ultrasound provides a real-time imaging platform to access and deliver therapy to organs and tissues outside of the bowel lumen. The bile and pancreatic ducts can be directly accessed from the stomach and duodenum, offering an alternative to ERCP when this fails or is not feasible.
