Influence of Probiotics Administration Before Liver Resection in Liver Disease

The aim of this study is to evaluate the effect of the administration of probiotics on intestinal barrier function in patients with chronic liver disease (fibrosis stage F3 or F4) operated for hepatocellular carcinoma. 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. Then the main criterion to demonstrate the effectiveness of a diet enriched with probiotics is the AUC of circulating levels of endotoxins ((pg/ml) using the Limulus amebocyte lysate (LAL) assay) observed for each patient. Endotoxin levels were analysed on samples of peripheral blood. The two arms of equal size will be considered significantly different when compared to the AUC of circulating levels of endotoxin if the null hypothesis (AUC is the same for both arms) is rejected in favor of the alternative hypothesis (AUC differs between the two arms - Wilcoxon test) In order to estimate the sample size to distinguish between the two hypotheses with sufficient power, the median AUC in arm without probiotics be used to form two groups of patients in each arm. Thus, half of the patients without probiotics have a higher median AUC arms. Then, this proportion may be compared to the proportion of patients with probiotics have an AUC greater than the median of the group without probiotics. The secondary endpoints are: * Evaluation of systemic inflammation by assay of inflammatory cytokines * IL-2, IL-4, IL-6, IL-8, IL-10, GM-CSF, IFNa, TNFa * CRP * Leukocyte count * The post-operative liver function monitored in the usual manner * Standard Liver function tests between J1 and J5 (Bilirubin, prothrombin, ammonia) * Indocyanine green clearance with measuring retention rates at 15 minutes between J1 and J3 * Monitoring of overall postoperative complications and specifically liver failure and infectious complications at 3 months.
