Good cooperation between the hepatologist, surgeon and anesthesiologist is required to determine the appropriate perioperative nutritional management for the liver transplant patient. For preoperative risk stratification, nutritional assessment according to resting energy expenditure by indirect calorimetry, and body cell mass by bioelectrical impedence analysis, may be superior to anthropometric parameters. When considering impaired glucose tolerance in the early postoperative period, requirements of energy intake and macronutrients are no different from those established in major abdominal surgery. Preference should be made to use the enteral route whenever possible. Fat emulsions containing medium- and long-chain triglycerides have neither a negative impact on reticulo-endothelial system recovery of the graft, nor any obvious metabolic advantages. There is no evidence for the routine use of branched-chain amino acids. Even in the case of good graft function, long term dietary evaluation and counselling may be useful. Impaired glucose tolerance, hyperlipidemia and hypercholesterolemia should be considered carefully. The role of preoperative nutritional therapy using oral supplements and the value of immune-enhancing substrates should be evaluated with special regard to a decrease in postoperative septic complications and for possible impact on immune tolerance after transplantation.
