Background/Aims: It has not determined whether post-transplant persistent hypersplenism (PTPH) occurs after living donor liver transplantation (LDLT). Methodology: One hundred and ninety-four patients who survived more than 6 months after LDLTs were examined for the evaluation to determine the incidence of PTPH (leukocyte counts <3,500/μL and/or platelet counts <7.5×104/μL). In addition, 154 patients without a splenectomy were evaluated for the risk factors for PTPH. Results: The incidence of PTPH was 20.1% (n=31/154), and the occurrence ranged between 1.1 and 9.9 years after the LDLT, with the mean follow-up periods of 3.3±2.5 years. Multivariate analysis showed that portal pressure >30mmHg at the time of the laparotomy (p<0.01) and post-LDLT small for size syndrome (p<0.01) are risk factors for PTPH. For those with severe portal hypertension (>30 mmHg at laparotomy), the splenectomy tended to give better survival rate (p=0.09) without increasing the rate of septic complications. Conclusions: Hypersplenism did persist in a proportion of patients after LDLT. A high-risk for PTPH, especially severe portal hypertension, may be an indication for a splenectomy during LDLT in order to achieve uncomplicated post-transplant recovery.
