EUS-guided biliary drainage has been developed as an alternative method for failed ERCP. EUS-BD can be divided into two main approach routes, such as transgastric or transduodenal approach. Also, EUS-guidedhepaticogastrostomy, choledochoduodenostomy, and gallbladder drainage have been reported. In this review, we described technical tips for each basic technique, including literature review. As advanced technique of EUS-BD, antegrade stone removal has been reported. More recently, electrohydraulic lithotripsy for bile duct stones under transluminal cholangioscopy guidance, hepaticojejunostomy stricture dilation through EUS-HGS route, or EUS-guided gastrojejunostomy have been reported. Although EUS-BD has various potential as treatment technique, treatment method should be selected for each patient's conditions.
