The Impact of Immunostimulating Nutrition on Infectious Complications After Upper Gastrointestinal Surgery: A Prospective, Randomized, Clinical Trial
Background and Aim : Immunomodulating nutrition is supposed to reduce the number of complications and lengthen of hospital stay during the postoperative period in patients after major gastrointestinal surgery . The aim of the study was to assess the clinical effect of immunostimulatory enteral and parenteral nutrition in patients undergoing resection for gastrointestinal cancer in the group of well-nourished patients . Material and Methods : Between June 1 , 2001 , and December 31 , 2005 , a group of 214 well-nourished patients was initially assessed ( 150 men , 64 women , mean age 61.2 years ) to participate in the study . Nine patients were subsequently excluded and the remaining 205 subjects were r and omly assigned in a 2 × 2 factorial design into 4 study groups , ie , st and ard enteral nutrition ( n = 53 ) , immunomodulating enteral nutrition ( n = 52 ) , st and ard parenteral nutrition ( n = 49 ) , and immunomodulating enteral nutrition ( n = 51 ) . The study was design ed to test the hypothesis that immunonutrition and enteral nutrition would reduce the incidence of infectious complications after upper gastrointestinal surgery ; the secondary objective of the study was to evaluate the effect of nutritional intervention on overall morbidity and mortality rates , and hospital stay . The study was registered in the Clinical Trials Data base – number NCT 00558155 . Results : The overall morbidity rate was 33 % and the incidence of individual complications was comparable between all groups . Infectious complications occurred in 26 of 102 patients given st and ard diets and in 22 of 103 patients receiving immunomodulatory formulas ( odds ratio 0.81 ; 95 % CI , 0.43–1.50 ) . There were no significant differences between infectious complications in patients using parenteral nutrition ( 22 of 100 patients ) and parenteral formulas ( 26 of 105 , odds ratio 1.14 ; 95 % CI , 0.61–2.14 ) . Neither immunostimulating formulas nor enteral feeding significantly affected secondary outcome measures , including overall morbidity and mortality rates , and hospital stay . Conclusions : Our study failed to demonstrate any clear advantage of routine postoperative immunonutrition in patients undergoing elective upper gastrointestinal surgery . Both enteral and parenteral treatment options showed similar efficacy , tolerance , and effects on protein synthesis .  Parenteral nutrition composed according to contemporary rules showed similar efficiency to enteral nutrition . However , because of its cost-efficiency , enteral therapy should be considered as the treatment of choice in all patients requiring nutritional therapy
