Anastomotic biliary stricture developing 3 weeks after living donor liver transplantation

A 54 year old gentleman with liver cirrhosis secondary to Hepatitis C. He received a right lobe graft from his nephew. This stricture was noted three weeks post transplant. The stricture was evident ton cholangiogram during ERCP (A: white arrow). A 12cm plastic stent of 10 French diameter was placed (B &  C: white arrows). There was a lot of sludge coming out of the stent and we suspect that the stent may get blocked sooner rather than later.
