Endoscopic Ultrasound-Guided Biliary Interventions in Liver Disease.

If endoscopic retrograde cholangiopancreatography (ERCP) fails in cases of biliary obstruction and jaundice, percutaneous drains have been traditionally the current second-line option. Endoscopic ultrasonography-guided biliary drainage (EUS-BD) with choledocoduodenostomy or hepaticogastrostomy is alternative modality that have shown equivalent or better technical and clinical success compared with percutaneous drainage. Similarly, EUS-guided gallbladder drainage has emerged as a therapeutic option in acute cholecystitis as well. Furthermore, EUS-BD avoids some of the pitfalls of percutaneous drainage. Current research in EUS-BD involves optimizing devices to improve technical and clinical success. In centers with advanced endoscopists trained in these procedures, EUS-BD is an excellent second-line modality.
