Total stricture of liver transplant biliary anastomosis resolved with peroral digital cholangioscopy and the non-flexible end of a 0.018-inch biliary guidewire.

A 64-year-old man underwent orthotopic liver transplantation due to hepatocellular carcinoma on liver cirrhosis diagnosed 2 years earlier. Three months after transplantation surgery, he presented with jaundice, and a cholangio magnetic resonance imaging scan revealed a biliary anastomosis stricture with marked kinking and retrograde dilatation. A multidisciplinary committee decided on an endoscopic approach.
