    Abstract:
    The technical success of cadaveric whole-size liver transplantation and better immunosuppressive drugs has extended the application of this life-saving procedure to include patients with irreversible acute and chronic liver diseases. However, because of the scarcity of cadaveric liver grafts, living-donor liver transplantation (LDLT) has emerged as an alternative to cadaveric-donor liver transplantation (CDLT), especially in Asia. In Korea, 8% of the population are hepatitis B virus (HBV) carriers, and the resultant HBV cirrhosis, with or without hepatocellular carcinoma (HCC), is common in the 40- to 60-year-old generation. Accordingly, many patients require orthotopic liver transplantation (OLT). In 1992, we started performing CDLTs in the Asan Medical Center. In 1994, the first successful pediatric LDLT was performed in Korea, on a 9-monthold infant with biliary atresia. In 1997, the first successful adult LDLT was performed in our department, using a left lobe, on a 37-year-old patient with HBV cirrhosis associated with HCC. Even after the first successful right-lobe LDLT, we faced the obstacle of anterior segment congestion of a right-lobe graft, and initiated reconstruction of the middle hepatic venous tributaries of a right-lobe graft in 1998. In 1999, we performed more than 100 OLTs a year. Insufficient graft size has hindered the expansion of adult LDLT, when the remaining left-lobe of potential donors is too small to assure donor safety. Dual two-left-lobe graft LDLT (transplanting from two donors into one recipient) was developed in 2000 to solve graft-size insufficiency and minimize donor risk. More than 200 OLTs a year have been performed since 2004, while broadening the indications for adult LDLT to near complete obstruction of the portal vein, with the application of intraoperative portography (IOP) and portal vein stenting. In 2007, 320 LTs were performed, including 276 adult LDLTs, 10 pediatric LDLTs, and 34 CDLTs (including 7 adult and 1 pediatric split-liver transplant). There has been no donor mortality in LDLT. With technical refinement and advanced perioperative care, the in-hospital mortality of recipients has dropped to 4%: attributed to the dedication of our liver transplantation team members.
