Session Name: Liver: Living Donor Liver Transplant and Partial Grafts
Session Date & Time: None. Available on demand.
*Purpose: The present study aims to report outcomes of adults following SLT in a single-center and compare this selected group with adults recipients following whole liver transplantation.
*Methods: Between 2010 and 2019, SLT conducted at a single-center were identified retrospectively by electronic medical records review. A 1:1 case-control match was performed to match patients following split liver transplant and adult patients receiving a whole liver graft in the same period. The random match analysis was based on recipient age (±10 years), MELD (±5 points), and indication for transplant. Demographic variables, surgical variables, postoperative outcomes and long-term complications in the two groups of patients were compared.
*Results: Twenty-one SLT were performed during the study period (SLT group) and 21 adults receiving a whole liver (WL group) were randomly generated. The median (IQR) age at transplant was 59 (49-63) for the SLT group and 59 (52-64) for the WL group (p=0.35). Recipient male gender proportion was higher, but not statistically different, in the WL group (52.4% vs 38.1% respectively;p=0.35). Recipient BMI (SLT=25.4 (23.8-28.2) vs WL=28 (23.8-32.7); p=0.11) and MELD (SLT= 23 (16-27) vs. WL= 25 (16.5-28); p=0.95) at transplant were similar between groups. The most common indication for liver transplant was Alcohol induced cirrhosis found in 7 (33.3%) recipients, followed by HCV cirrhosis in 4 (19%) and NASH in 3 (14.3%) recipients in both groups. Donor age (WL= 47 (33.5-66) vs. SLT= 16 (15-22) years, p=<0.001) and donor BMI (WL= 25.5 (21.3-31.2) vs SLT= 22.9 (20-24.7), p=<0.002) were significantly higher in the WL group compared to SLT group. Length of stay, ICU stay and readmission within 30 days post-transplant were similar between both groups. Re-transplantation occurred in one (4.8%) patient in the SLT group. This consisted of a patient who received a right lobe split liver and subsequently developed HAT within the first 7 days after LT. No recipients in the WL group were re-transplanted. No mortality occurred in neither of the groups. Graft survival at 1-, 3- and 5- year were similar between groups (100% vs 95% for all time periods, p=0.31). Patient survival at 1-, 3- and 5- year were 100% in both groups.
*Conclusions: SLT represents a feasible option to expand the donor pool with favorable outcomes in well-selected adult recipients.
