Abstract
|
|
|
|
Endoscopic retrograde cholangiopancreatography is the standard therapeutic approach for malignant distal biliary obstruction (MDBO). However, it can be challenging in patients with surgically altered anatomy, pyloric/duodenal obstruction, or failed biliary cannulation. Since the development of endoscopic ultrasound (EUS), EUS-guided biliary drainage (EUS-BD) has been increasingly performed. The current article provides a concise review of the latest practices and techniques of EUS-BD procedures for MDBO including EUS-assisted rendezvous, EUS-guided antegrade stenting, EUS-guided choledochoduodenostomy, and EUS-guided hepaticogastrostomy.
