Comparative study of rendezvous techniques in post-liver transplant biliary stricture

Figure 2 Guidewire technique. A: The percutaneous transhepatic biliary drainage (PTBD) catheter was located over the anastomotic stricture into the duodenum. The angle between the right hepatic duct and the common bile duct was steep (100°); B: The 0.035 inch guidewire was inserted through the PTBD catheter, and then the PTBD catheter was removed; C: The end of the guidewire was placed outside the papilla; D: The guidewire was inserted through a bottle-top metal-tip endoscopic retrograde cholangiopancreatography (ERCP) cannula, and then the ERCP cannula was advanced into the intrahepatic bile duct; E: Two inside stents were placed over the stricture in the anterior and posterior branches of the right hepatic duct in the recipient liver.
