Biliary complications after a right-lobe living donor liver transplantation

Right-lobe living donor liver transplantation (RL-LDLT) has become an acceptable procedure for adult patients with end-stage liver disease in this decade. However, biliary complications in RL-LDLT remain a serious problem: the incidence of anastomotic biliary leakage and stricture after RL-LDLT is reported to be 4.7%–18.2% and 8.3%–31.7%, respectively. The incidence varies according to the type of biliary reconstructions between Roux-en-Y hepaticojejunostomy and duct-to-duct biliary reconstruction. The anatomical biliary diversity of a right-lobe graft makes it difficult to reconstruct the biliary system. Indeed, most biliary strictures in patients with duct-to-duct reconstruction develop in multibranched fashion. In this regard, endoscopic biliary stenting appears to be efficacious for treating multibranched biliary strictures because multiple stenting permits the drainage of each segmental branch of the stricture. In this review, we describe various aspects of biliary complications occurring in RL-LDLT and their treatment.
