Double soft-tipped guidewire facilitating the rendezvous technique for ERCP.

The rendezvous technique has been a traditional salvage technique when transpapillary cannulation is difficult [1] [2]. For the rendezvous technique, a guidewire is inserted via a percutaneously or an endosonographically created route (endoscopic submucosal resection [ESR]) into the duodenum through the papilla and then caught under duodenoscopy to ensure transpapillary access from the duodenum. After successfully approaching the duct from the duodenum along the guidewire, the wire must be exchanged or inverted to use the seeking tip to seek upward ducts.
