Imaging of biliary complications in recipients of right-lobe living donor liver transplantation

Abstract

Right-lobe living donor liver transplantation (RL-LDLT) is a common method devised in order to fulfill the demands of donor organ shortage in adult patients with end-stage liver diseases. However, biliary complications remain as the "Achilles' heel" of RL-LDLT, with wide variety of incidence among transplantation centers. Patients with biliary complications after RL-LDLT may have similar clinical presentations to those with other causes of graft dysfunction. Therefore, radiological evaluation plays a key role for differential diagnosis of such complications. In this article, we discuss the various methods of biliary reconstruction and imaging findings of common and uncommon biliary complications in recipients of RL-LDLT.
