Core Tip

Core Tip: Endoscopic retrograde cholangiopancreatography is the current standard of care for bile duct obstruction but is not always possible. The traditional rescue modality is percutaneous transhepatic biliary drainage which has many disadvantages. Endosonography-guided biliary drainage is a new promising interventional technique, showing many advantages over percutaneous biliary drainage and is able to fully replace it when the expertise is available. Developing new devices, training models and guidelines is expected to make this procedure easier, safe and widely accepted in the near future.
