BACKGROUND Endotoxemia after major vascular surgery has been suggested to be caused by the passage of bacterial endotoxins through the gut. Early enteral feeding has been reported to prevent bacterial translocation. Therefore, we investigated the incidence of endotoxemia in 12 patients with normal liver function after elective surgery for abdominal aortic aneurysm. METHODS Blood samples were taken from the brachial vein of each patient before surgery, 1 day after surgery, and 3 days after surgery. The endotoxin concentration was measured using a chromogenic endotoxin-specific assay. RESULTS The endotoxin concentration was significantly higher one day after surgery (2.15+/-1.36 pg/ml) than that before surgery (1.27+/-1.00 pg/mL), (p<0.05). The mean endotoxin concentration in the patients after early oral feeding (0.74+/-0.74 pg/ml) was significantly lower than that in the patients who could not eat (1.58+/-0.48 pg/ml). CONCLUSIONS A low concentration of systemic endotoxins can be observed after surgery for abdominal aortic aneurysm, and early oral feeding prevented this elevation.

D004926 Escherichia coli A species of gram-negative, facultatively anaerobic, rod-shaped bacteria (GRAM-NEGATIVE FACULTATIVELY ANAEROBIC RODS) commonly found in the lower part of the intestine of warm-blooded animals. It is usually nonpathogenic, but some strains are known to produce DIARRHEA and pyogenic infections. Pathogenic strains (virotypes) are classified by their specific pathogenic mechanisms such as toxins (ENTEROTOXIGENIC ESCHERICHIA COLI), etc. Alkalescens-Dispar Group,Bacillus coli,Bacterium coli,Bacterium coli commune,Diffusely Adherent Escherichia coli,E coli,EAggEC,Enteroaggregative Escherichia coli,Enterococcus coli,Diffusely Adherent E. coli,Enteroaggregative E. coli,Enteroinvasive E. coli,Enteroinvasive Escherichia coli
