Multivisceral and orthotopic liver/small bowel transplantations have been performed to treat patients with intestinal failure associated with liver failure induced by parenteral nutrition. The aim of this experimental study was to determine the experimental liver-small bowel harvesting and transplantation technique that achieves the best compromise between liver and intestine ischemia times in pigs. Initial portal revascularization of the liver which reduces the hepatic warm ischemia time after cold ischemia preparation of the graft immersed in lactated ringer's solution at 4 degrees C, reduce the risk of primary non function of the graft.
