title: [Early enteral nutrition in patients treated with major surgery of the abdomen and the pelvis].
abstract: Hypercatabolism after operations has a negative influence on nutritional status, the healing process, infective complications and hospital stay. Moreover, the immune status of the patient has been shown to be equally important for septic morbidity and mortality. It is extensively accepted that in critical situations, an adequate nutritional support (enteral or parenteral) is absolutely necessary, but subjects such as the best way of feeding, the kind of nutrients to be used and the administration time are still debatable issues. Our aim was to evaluate the effectiveness (nutritional and immunological features) and clinical outcomes (septic morbidity and mortality) of total parenteral nutrition (TPN), early enteral nutrition and early enteral immunonutrition (EEN, EEIN) in 171 patients undergoing major abdominal and urological surgery for neoplastic pathology. Our prospective, randomised study showed no significant differences among the 3 nutritional supports (TPN, EEN, EEIN) with regard to restoration of normal nitrogen balance during the acute phase of surgical stress. No correlations were found in the 3 groups with immunoglobulin percentage, lymphocyte subpopulations and their functional patterns as studied by specific immunological tests. The skin test, on the other hand, seems to be more representative of the immune condition of the patients, demonstrating a faster improvement in immunological status in the EEIN group as compared to the control group. A smaller percentage of septic morbidity and mortality was found in both enteral nutritional groups (EEN and EEIN), although there was a statistically significant difference only between the TPN and EEIN groups. The hospital stay was 3.5 days shorter in enteral feeding patients (EEN, EEIN). Finally, EEN was less expensive than the other nutritional conditions, this result depending on the cost of the different materials used (infusion sets, linear filters, prepacked diets, etc.).
