Study of perioperative enteral immunonutrition in patients with gastrointestinal cancer / 中国现代普通外科进展

ABSTRACT

Objective:To evaluate the effects of perioperatively administrated enteral immunonutrition in gastrointestinal cancer patients on immune and inflammatory responses,nutrition states and postoperative morbidity.Methods:Sixty patients with gastrointestinal cancer were divided randomly into two groups.Two groups perioperatively(from preoperative day 5 to postoperative day 7) received an supplemented diet with arginine,RNA,and ?-3fatty acids(immunonutrition group;n=30) or an isoenergetic and isonitrogenous standard diet (standard-nutrition group;n=30).All variables of immune and inflammatory responses,nutrition states and postoperative morbidity were measured on preoperative day 5 and postoperative day 1,4 and 8.Results:On postoperative day 4 and 8,most immune variables and prealbumin in the immuno-group were significantly higher than those in the standard-group(P0.05),and inflammatory variables as CRP in the immunonutrition group were significantly lower than those in the standard group.In the immunonutrition group,there were significantly fewer patients who experienced postoperative complications and shorter days of hospital stay compared with standard group(P0.05).Conclusion:The perioperative administration of enteral immunonutrition in gastrointestinal cancer patients can significantly modulate the postoperative immunosuppressive and inflammatory responses at the early postoperative day,can significantly decrease the occurrence of infectious and overall postoperative complications as well as the length of hospital stay.
