Abstract
Bacterial translocation is a frequent complication in portal hypertension related to cirrhosis in the human clinical area The aim of this study was to verify the existence of intestinal bacterial translocation to mesenteric lymph nodes in male Wistar rats with triple partial portal vein ligation during short 48 h and longterm 1 month postoperative evolutionAt 48 h ileal total aerobes bacteria p 0001 and Lactobacillus decrease in shamoperated SO and portal hypertensive PH rats At 1 month ileal Enterococci and Streptococcus sp show a statistically significant decrease in SO and PHrats Lactobacillus decreases in the colon in SO p 001 and in PHrats p 0001 At 1 month colonic Enterococci decreases compared to control p 0001 and SOrats p 001 These intestinal microfloral changes are associated with bacterial translocation to mesenteric lymph nodes at 48 h 50 p = 0004 and 1 month 100 p 0001 of postoperative evolution in PHratsThe enlargement of the stenosed portal tract related to triple partial portal vein ligation in the rat since it increases the resistance to the portal blood flow may be a key factor involved in one of the pathological consequences of portal hypertension as is bacterial translocation to mesenteric lymph nodesThe support and secretarial assistance of Maria Elena Vicente and the translation into English by Elizabeth Mascola are gratefully acknowledged We are also indebted to Pedro Cuesta from the Mathematical Unit of Complutense University of Madrid Spain for the statistical study This study was supported in part by grants from the MMA Foundation FMM Ref no PA 3077/2008 and the Department of Health Institute of Health Sciences and the Autonomous Government of CastillaLa Mancha Ref numbers 0404700 and PI2007/64
