Liver Pathology after Transplantation of Short-Term Preserved Canine Liver with Euro-Collins or UW Solution / 대한이식학회지

ABSTRACT

PURPOSE: In living donor partial liver transplantation, the organ cold preservation time is relatively short, thereby, Euro-Collins (EC) solution could be used with comparable result to University of Wisconsin (UW) solution. METHODS: About 70% partial liver was harvested and reimplanted after 3.5 hours of cold preservation with EC or UW solution in same mongrel dog weighing about 25 kg. In 5 cases EC solutions were used, and UW solutions were used in another 5 cases. Blood sample and liver biopsy specimens were taken just before donor hepatectomy, postreperfusion 1 hour, 7 days and 14 days after operation. Serum aspartate aminotransferase (AST), alkaline phosphatase (ALP), and lactate dehydrogenase (LDH) were monitored, and morphologic grading of liver injury was performed as Spiegel et al. reported in 1999. RESULTS: Total ischemic time was 4 hours and 27 minutes in average. At 1 hour after reperfusion, there were no significant differences in liver enzyme and morphological score between the UW solution group and the EC group. Survival rate was similar in two groups; 2 dongs were alive at postoperative 7th day, and 1 dog was alive at postoperative 14th day in each group. CONCLUSION: In living donor partial liver transplantation where both operations could be performed simultaneously with relatively short graft preservation time, EC solution could be used with comparable results to UW solution.
