A RANDOMIZED, CONTROLLED, CLINICAL TRIAL TO COMPARE PERIPHERAL PARENTERAL NUTRITION (PeriOlimel N4-E) VS CONVENTIONAL FLUID THERAPY IN ENHANCED RECOVERY AFTER SURGERY (ERAS) PROTOCOL IN COLORECTAL CANCER SURGERY.

Primary objectives: The main objective is to determine if perioperative nutritional support with PeriOlimel N4-E, that reaches nutritional requirements of ERAS protocol for colorectal cancer surgery patients, can improve nutritional status so it decreases postoperative complications, hospital length of stay and costs, compared to conventional fluid therapy administration since patients receive oral nutrition at day 3-5.
Primary endpoints: We set the primary endpoint as the presence of surgical postoperative complications during the first postoperative month.
