Endoscopic ultrasound-guided biliary drainage (EUS-BD) has been increasingly used as an alternative in patients with biliary obstruction who fail endoscopic retrograde cholangiopancreatography. The advantage of EUS-BD is one-step internal drainage, compared with percutaneous biliary drainage. Recent studies have revealed that cumulative technical success and adverse event rates were 82-100% and 0-21.2%, respectively. Several adverse events have been reported such as bleeding, perforation and peritonitis, which sometimes require surgical and radiological intervention. Therefore, we should understand the mechanism of adverse events and the technique to prevent and manage them. Here, we focus on the progress and problems of EUS-BD referring to articles which have been published until now.
