Reverse rendezvous with endoscopic retrograde cholangiography and percutaneous transhepatic cholangio drainage: who meets whom?
14 December 2018 (online)
A 47-year-old severely ill Caucasian man presented with cholestasis (bilirubin 17.8 mg/dL) due to primary sclerosing cholangitis. Endoscopic retrograde cholangiography (ERC) showed high grade strictures of the common bile duct (CBD), dilation of the common hepatic duct (CHD), and left hilar obstruction ([Fig. 1 a]). Attempts to maneuver 5 – 7-Fr bougies across the distal CBD stenosis were not successful.
Via left-sided percutaneous transhepatic cholangio drainage (PTCD), retrograde access to the CBD was not possible even after simultaneous transpapillary wire guidance ([Fig. 1 b]). Therefore, a 1.2-mm biopsy forceps (SpyBite; Boston Scientific, Ratingen, Germany) was introduced percutaneously through an 8-Fr bougie into the dilated CHD to grab the transpapillary 0.025-inch wire. The wire was carefully exteriorized in a reverse rendezvous maneuver ([Fig. 1 c, d], [Video 1]). Given the lack of bougienage options, a 5.2-Fr angiography catheter (Super Torque Plus; Cordis, Baar, Switzerland) was inserted as a temporary spacer across the papilla under duodenoscopic view. Upon PTCD exchange, spurting bleeding from the access site was stopped by upgrade to an 8.5-Fr Yamakawa drain (Peter Pflugbeil GmbH, Zorneding, Germany). Parenchymal damage from initial wire manipulation was suspected, so the percutaneous tract was subsequently occluded with hemostyptic gelatine (Gelita; B. Braun, Melsungen, Germany), and a transpapillary 8.5-Fr pigtail stent was inserted.

The patient gained 10 kg in weight and the bilirubin level persistently dropped to 0.8 mg/dL. After repeated stent upgrades and dilations ([Fig. 1 e]), dysplasia was ruled out by cholangioscopic biopsies. After 20 months, the patient was well and continued to have regular follow-up with no evidence of recurrence of cholestasis.
To our knowledge, reverse rendezvous, with percutaneous uptake of a transpapillary wire, has not been reported previously. The “lucky punch” of being able to grab the transpapillary wire with a port-guided forceps can be facilitated by C-arm rotation. Unsheathed transparenchymal wire extraction is not recommended as the wire may cut the liver parenchyma, necessitating hemostyptic occlusion of the percutaneous tract, as in our patient. Reverse ERC-PTCD rendezvous is a nonstandard rescue maneuver that can offer significant benefit in technically demanding situations.
