Core Tip

Core Tip: Biliary complications are the most common surgical complications after liver transplantation, and represent a major source of morbidity and mortality in liver transplant recipients. Magnetic resonance cholangiopancreatography is the gold standard for the non-invasive diagnosis of intra- and extrahepatic biliary complications. Computed tomography may also be helpful for the assessment of biliary complications, and it is often used due to its more widespread availability as compared to that of magnetic resonance imaging.
