Abstract
OBJECTIVE Early enteral nutrition with fiber-containing solutions plus Lactobacillus may reduce bacterial translocation and minimize the incidence of infections after surgery. METHODS In a prospective, randomized trial in three groups (n = 30/group) of patients after major abdominal surgery, we compared our previous regimen with parenteral nutrition or fiber-free enteral nutrition (group A) with enteral fiber-containing nutrition with living Lactobacillus (group B) and heat-killed Lactobacillus (group C). The main endpoint was the development of bacterial infection. Other analyzed parameters were the durations of antibiotic therapy and hospital stay, non-infectious complications, side effects of the nutrition, and onset of bowel movement. Routine parameters, nutritional parameters, and cellular immune status in the blood were measured preoperatively and on 1, 5, and 10 d postoperatively. RESULTS The incidence of infections was significantly lower (P = 0.01) in groups B and C with enteral nutrition containing fibers (10% each) than in group A (30%). Patients in group B received antibiotics for a significantly shorter time (P = 0.04) than did the patients in groups A and C. The length of hospital stay and the incidence of non-infectious complications did not differ significantly. Fibers and lactobacilli were well tolerated. There were no general benefits of living Lactobacillus as opposed to heat-killed Lactobacillus in the entire study population, but benefits were observed in the patients with gastric and pancreas resections, although no statistical analysis was done due to their small numbers. CONCLUSIONS Early enteral nutrition with fiber-containing solutions reduced the rate of postoperative infections in comparison with parenteral nutrition and fiber-free enteral formula. Addition of living Lactobacillus seemed to increase the benefits in patients with gastric and pancreatic resections.

Abstract
INTRODUCTION Early enteral nutrition with fibre and probiotics has been effective in preventing bacterial translocation and is therefore expected to reduce the incidence of postoperative bacterial infections. PATIENTS AND METHODS In a prospective randomized trial including 172 patients following major abdominal surgery or liver transplantation, the incidence of bacterial infections was compared in patients receiving either a) conventional parenteral or enteral nutrition, b) enteral nutrition with fibre and lactobacillus plantarum 299 or c) enteral nutrition with fibre and heat inactivated lactobacilli (placebo). Liver transplant recipients were also treated with selective bowel decontamination (SBD). Routine laboratory parameters, nutritional parameters and the cellular immune status were measured preoperatively and on postoperative days 1, 5 and 10. RESULTS Patients were comparable regarding preoperative ASA-classification, Child-Pugh classification of cirrhosis, operative data and immunosuppression. The incidence of bacterial infections after liver, gastric oder pancreas resection was 31 % in the conventional group a) compared to 4 % in the lactobacillus-group b) and 13 % in the placebo-group c). In the analysis of 95 liver transplant recipients, 13 % group b)-patients developed infections compared to 48 % group a)-patients and 34 % group c)-patients. The difference between groups a) and b) was statistically significant in both cases. In addition, the duration of antibiotic therapy was significantly shorter in the lactobacillus-group. Cholangitis and pneumonia were the most frequent infections and enterococci the most frequently isolated bacteria. Fibre and lactobacilli were well tolerated in most cases. CONCLUSION Fibre and probiotics could lower the incidence of bacterial infections following major abdominal surgery in comparison to conventional nutrition with or without SBD. With this new concept, costs can be reduced by shortening the duration of antibiotic therapy and sparing SBD.
