It has been shown that the nutritional state of the donor may affect the outcome of liver transplantation. However, many donors staying in the intensive care unit for a long period are in a reduced nutritional state. In this study, we investigated the effects of various methods of nutritional repletion on the outcome of liver transplantation in pigs. Donor pigs were divided into three groups according to the nutritional pretreatment given for 7 days before harvesting: group I were fasted and received intravenous administration of saline; group II were fed orally; group III were fasted, but given 20% glucose intravenously. Donor livers were stored for 4 hr in cold Euro-Collins’ solution and transplanted. The serum AST level 24 hr after reperfusion remained at a lower level in group III compared with those in groups I and II. Bile production of the liver after transplantation was also well recovered in group III. The glycogen content of the liver at harvesting, which was completely consumed in group 1, was well preserved in groups II and III. These storages in both groups were rapidly consumed 1 hr after reperfusion. On the other hand, ATP content of the liver in groups I, II, and III, which were at a similar level at harvesting, were markedly decreased 4 hr after cold preservation and, 1 hr after reperfusion, recovered to 26%, 48%, and 73% of that before preservation, respectively. The mean survival time in group III was 37.2 days, significantly longer than 5.8±0.7 and 9.8±2.0 days in groups I and II, respectively (P<0.01). These results show that the favorable outcome of liver transplantation depends on the glycogen storage in the donor liver, and also on ATP generation after reperfusion. Furthermore, it was suggested that ATP generation was affected by some unknown factor related to the method of nutritional repletion.
