Endoscopic ultrasound-guided bile duct access for rendezvous ERCP drainage in the setting of intradiverticular papilla.

Cannulation of an intradiverticular papilla during endoscopic retrograde cholangiopancreatography (ERCP) can be challenging. We present here a technique for endoscopic ultrasound-guided puncture of the common bile duct followed by rendezvous ERCP for biliary drainage through the native intradiverticular papilla.
