* Conversion from the PEHBD/D1 route. EUS-RV: endoscopic ultrasound-guided rendezvous; DEHBD/D2: distal extrahepatic bile duct/duodenal second part; PEHBD/D1: proximal extrahepatic bile duct/duodenal bulb; LIHBD/S: left intrahepatic bile duct/stomach; RIHBD/D1: right intrahepatic bile duct/duodenal bulb; GW: guidewire.
