Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
The 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.

Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
The aim of the study is to evaluate the effect of preoperative nutritional supplementation for 7 days with a formula enriched with immunonutrients compared to an isocaloric and isoproteic formula, on the plasma concentration of BCAAs in patients undergoing elective colorectal surgery. A randomized, double-blind, controlled trial will be conducted with 63 patients per group. The concentration of BCAAs will be measured prior to the 7 days of nutritional supplementation and will be repeated on the day of the surgical intervention before the procedure. The supplements for both groups will provide 500 calories, 41 g of protein, 60 g of carbohydrates, and 11 g of lipids; the supplement for the intervention group is additionally fortified with immunonutrients. Patients will be instructed to consume the supplement daily for the 7 days prior to the surgical intervention. Patients in both groups will be advised to maintain their usual food intake.
The investigators hypothesized that if an oral formula with immunonutrients is administered compared to an isocaloric and isoproteic formula without them for 7 days in the preoperative period in patients undergoing elective colorectal surgery, there will be an increase in the plasma concentration of BCAAs in the intervention group.

Sample Size:
For the sample size calculation, it was considered that patients in the immunonutrition intervention group will have a 21% increase in plasma branched-chain amino acid concentration, as reported in the study by Cangiano C et al. Therefore, considering a type 1 error (α) of 0.05 with one tail, and a type 2 error (β) of 0.20, and using the formula N = 2s² (Zα + Zβ)² / Δ², a sample size of 63 subjects per group is obtained.
