Diagnosis of biliary strictures after liver transplantation: Which is the best tool?

Figure 1 Differences in underlying liver disease prior to transplantation. NoST = no apparent biliary stenosis in ERC. AST = anastomotic stricture in ERC. ITBL = ischemic type biliary lesions in ERC. ALF = acute liver failure; AlCi = alcoholic liver cirrhosis; HBV = chronic hepatitis B virus infection; HDV = chronic hepatitis D virus superinfection; HCV = chronic hepatitis C virus infection; HCC = hepatocellular carcinoma; n.s. = not significant.

Figure 2 Comparison of ERC and MRC in posttransplant biliary stenosis. ITBL type III with hilar stenosis (arrow) and multiple peripheral duct stenoses. Left: MRC, right: ERC. The dominant hilar stenosis (arrow) is seen with both methods. The peripheral stenoses are better seen in ERC.
