The administration of nutritional supplements known as immunonutrition before gastrointestinal surgery has been shown to improve clinical outcomes; however, the mechanisms underlying these benefits remain inconclusive.\n\nThe objective of the study is to evaluate the effect of preoperative nutritional supplementation with an immunonutrient-enriched formula compared to an isocaloric and isoproteic formula on plasma BCAA concentration in patients undergoing elective colorectal surgery. A double-blind, randomized controlled clinical trial will be conducted. Patients will be required to drink the supplement daily for the 7 days preceding the surgical intervention. Patients in both groups will be instructed to maintain their usual food intake. During the study, there will be two patient assessments and a review of medical records to document the outcomes.",[90],"Colorectal Surgery",[90,92,93,94,95],"Immunonutrition","Enhanced Recovery After Surgery","Preoperative Care","Amino Acids Branched-Chain","2026-03-23",{"date":98,"type":99},"2026-03-27","ACTUAL",{"date":101,"type":99},"2023-05-25",{"date":103,"type":84},"2026-12-31",{"name":5,"class":6},1]
