Endoscopic Ultrasound-Guided Biliary Drainage

Abstract

Endoscopic ultrasound (EUS)-guided biliary drainage is an emerging technique that combines the advantages of the endoscopic and percutaneous approaches, without the inconveniences and discomfort of an indwelling external catheter. There has been growing interest and experience in EUS-biliary drainage. Several different EUS-guided techniques have been developed to access the obstructed biliary tree from either the stomach or duodenum, according to the location of the stricture, the anatomy of the patient, and the experience of the endoscopist.
