After hepatectomy, kinetic of endotoxemia have been studied previously and the evolution will be summarized by the area under the plasma concentration versus time curve (AUC) of circulating endotoxin levels measured before surgery and at 5 different times analysis after hepatectomy. At 12 hours, portal hypertension and its consequences on gut permeability (impaired barrier function, bacterial translocation) are highest with peak of circulating endotoxins. The decreasing of endotoxemia curve is observed between the 2nd and 3rd day (end of liver regeneration and early liver architectural reorganization). On the 5th day, persist measurable but not deleterious to liver restructured and theoretically functional rates.
