Abstract

Endoscopic ultrasound (EUS) was originally devised as a novel diagnostic technique to enable endoscopists to stage malignancies and acquire tissue. However, it rapidly advanced toward therapeutic applications and has provided gastroenterologists with the ability to effectively treat and manage advanced diseases in a minimally invasive manner. EUS-guided biliary drainage (EUS-BD) has gained considerable attention as an approach to provide relief in malignant and benign biliary obstruction for patients when endoscopic retrograde cholangiopancreatography (ERCP) fails or is not feasible. Such instances occur in those with surgically altered anatomy, gastroduodenal obstruction, periampullary diverticulum or prior transampullary duodenal stenting. While ERCP remains the gold standard, a multitude of studies are showing that EUS-BD can be used as an alternative modality even in patients who could successfully undergo ERCP. This review will shed light on recent EUS-guided advancements and techniques in malignant and benign biliary obstruction.
