Immunonutrition in elective colorectal surgery and early inflammatory response.

Background: Immunonutrition has gained increasing interest over years, enough to be recommended in several international guidelines and to be included in the ERAS protocol for colorectal surgery. Although clinical advantages have been proved for malnourished cancer-affected patients, its role is more controversial in other settings. We evaluated the impact of immunonutrition in major colorectal elective surgery for benign and malignant diseases, regardless of the preoperative nutritional status.
