简要总结
The aim of the study was to assess the clinical effect of immunomodulating enteral nutrition in patients undergoing resection for gastrointestinal cancer. 196 subjects were randomly assigned into two study groups: standard and immunostimulating. The study failed to demonstrate any clear advantage of routine postoperative immunonutrition in patients undergoing elective upper gastrointestinal surgery
详细描述
Background&Aim: The administration of immunomodulating enteral diets during postoperative period in patients after major gastrointestinal surgery is intended to reduce the number of postoperative complications and to shorten the hospital stay. The aim of the study was to assess the clinical effect of enteral immunostimulatory nutrition in surgical patients.
Material and Methods
196 patients undergoing resection for pancreatic and gastric cancer were randomized in double-blind manner to receive early postoperative enteral nutrition with immunostimulating diet (IMEN group: formula supplemented with arginine, glutamine, omega-3 fatty acids) or oligopeptic control (SEN group) between June 2004 and September 2007. Enteral nutrition was started 6 hours after surgery and continued for 7 days, up to target volume of 100 ml/h. All malnourished patients requiring preoperative nutritional therapy were excluded for the study and treated preoperatively. Outcome measures were: number and type of complications, length of hospital stay, mortality, treatment tolerance, liver and kidney function.
Results: One hundred eighty-three patients (91 in SEN, 92 in IMEN group, 69 F, 114 M, mean age 61.2) of 196 initially enrolled were analyzed. There were 2 deaths in both groups. Median postoperative hospital stay was 12.4 days (SD 5.9) in SEN group and 12.9 days (SD 8.0) in IMEN group (p=0.42). Complications were observed in 21 patients (23.1%) in SEN and 23 (25.2%) in IMEN group (p>0.05). 4 (4.4%) patients in SEN group and 4 (4.4%) in IMEN had surgical complications (p>0.05). There were no differences in liver and kidney function, visceral protein concentration and treatment tolerance.
Conclusion: Clinical and laboratory parameters show no benefit of immunomodulating enteral nutrition over standard enteral nutrition in patients after major gastrointestinal surgery as far as complications, hospital stay, mortality and treatment tolerance and safety are considered.
