    Abstract:
    BACKGROUND: The Model of End-Stage Liver Disease (MELD) scoring system can predict short-term survival among patients awaiting liver transplantation and is used to allocate organs prioritizing liver transplantation. Patients with high MELD scores have been reported to have worse early graft dysfunction and survival. However, recent studies have shown that patients with high MELD scores had satisfactory graft survival, although they showed more postoperative complications. In this study, we examined the effect of the MELD score on the short-term and long-term prognosis of living donor liver transplantation (LDLT). METHODS: This study included 102 patients who underwent LDLT in our institution between 2005 and 2020. The patients were divided into 3 groups according to MELD score (low MELD group: ≤20, moderate MELD group: 21-30, and high MELD group: ≥31). Perioperative factors were compared among the 3 groups, and cumulative overall survival rates were calculated using the Kaplan-Meier method. RESULTS: The patients' characteristics were comparable, and the median age was 54 years. Hepatitis C virus cirrhosis was the most common primary disease (n = 40), followed by hepatitis B virus (n = 11). The low MELD group consisted of 68 patients (median score: 16, 10-20); the moderate MELD group, 24 patients (median score: 24, 21-30); and the high MELD group, 10 patients (median score: 35, 31-40). The mean operative time (1241 min versus 1278 min versus 1158 min, P = .19) and mean blood loss (7517 mL vs 11162 mL vs 8808 mL, P = .71) were not significantly different among the 3 groups. The vascular and biliary complication rates were similar. The periods of intensive care unit and hospital stay tended to be longer in the high MELD group, but the difference was insignificant. The 1-year postoperative survival rate (85.3 % vs 87.5 % vs 90.0 %, P = .90) and overall survival rate were also not significantly different among the 3 groups. CONCLUSIONS: Our study showed that LDLT patients with high MELD scores do not have a worse prognosis than those with low scores.
