Abstract
AIM: To analyze the MR findings of early and late biliary complications after orthotopic liver transplantation (OLT) and to evaluate the clinical value of MR cholangiopancreatography (MRCP) combined with MR cross-sectional images in diagnosing biliary complications after OLT.
METHODS: Fifty-seven consecutive patients with clinical suspicion of biliary complications after receiving OLT were evaluated on the basis of MRCP and MR cross-sectional images, the latter including T1W axial unenhanced and Gadolinum-enhanced sequences, Gadolinum-enhanced VIBE sequences, unenhanced T2W axial images and coronal True-FISP sequences. The diagnostic accuracy rates were compared between MRCP and MRCP combined with MR cross-sectional images.
RESULTS: The incidence of biliary complications after OLT was 64.9% (37/57). The final diagnoses were as follows anastomotic stricture (n = 14), nonanastomotic stricture (n = 8), solitary biliary stone or sludge (n = 5), cholangitis and periangiocholitis (n = 3), biloma (n = 3), donor-to-recipient common bile duct disproportion (n = 3), and elongation of extrahepatic biliary duct (n = 1) ......
