Abstract

Endoscopic retrograde cholangiopancreatography (ERCP) is the workhorse for biliary and pancreatic ductal interventions. Despite advances in both endoscopes and accessories for ERCP, it still has limitations in the presence of altered anatomy, luminal obstruction hindering access to the papilla, and proximal duct obstructions by tight stricture, calculi or intraductal growth. Endoscopic ultrasound-guided biliary drainage (EUS-BD) and EUS-guided pancreatic duct drainage (EUS-PDD) have expanded the rescue procedures after failed ERCP. This review discusses the techniques and results of various EUS-BD procedures, as well as EUS-PDD.
