[Effect of liver passage on peripheral glucose and hormone concentrations in early postoperative enteral nutrition].
Early postoperative disorders of blood glucose homeostasis and its hormonal regulation do not allow a normal caloric enteral or parenteral substrate supply in this period. Eleven land pigs were investigated to find out how the surgical trauma of a partial gastrectomy influences the absorptive capacity of the small intestine and the hormonal regulation after intraduodenal administration of a glucose solution. We therefore conducted portal vein measurements to correlate the influence of the liver passage of early postoperative changes in blood glucose and hormonal levels. Our data show that neither the porto-arterial differences in blood glucose nor those in hormonal concentrations are significant. Therefore, we conclude that peripheral measurements can be used as good and reliable parameters for such investigations of absorption or hormonal regulation in the early postoperative period.
