Split Liver Transplantation / 대한이식학회지

ABSTRACT

PURPOSE: Split liver transplantation (SLT) offers an effective way of increasing the donor pool. However, it is often difficult to perform SLT under current allocation system. We retrospectively analyzed the outcome of the patients who had undergone SLT in Seoul National University Hospital. METHODS: From the first case of SLT in Korea on November 4, 1998, 8 patients underwent SLT in our center. Three adult patients received extended right liver graft and five child patients received left lateral section graft. All liver were split by in-situ method. RESULTS: All adult patients were alive. One adult patient developed hepatic artery thrombosis one month after SLT and underwent retransplantation due to graft failure. Another patient developed biliary leakage and had to undergo operative bile duct revision. Two of child patients were died of pneumonia and hepatic failure due to HBV hepatitis, respectively. One child patient suffered from hepatic venous stricture and persistent ascites and received interventional therapy. Overall 3-year patient survival rate was 87.5% and graft survival rate was 75.0%. No primary nonfunction developed and three patients (37.5%) suffered form vascular or biliary complications. CONCLUSION: The results of SLT were similar to that of conventional deceased donor liver transplantation. Although SLT is technically difficult and increase the risk of vascular or biliary complications just like living donor liver transplantation (LDLT), its result might be acceptable and it could be a successful method to expand the donor pool if it would be performed in the center experienced in LDLT.
