Core Tip
Core Tip: This quasi-experimental, period difference study examined the Nutritional Risk Screening 2002 (NRS-2002) instructed individualized nutritional intervention among postoperative colorectal cancer patients. The Overall intervention protocol included preoperative nutrition assessment via NRS-2002, initiation of enteral nutrition as soon as possible postoperatively, customized energy-protein supply for different risks stratification, and supplementary oral nutritional (ensure) input in addition to dynamic adjusted formula usage during the perioperative period. These interventions were correlated with faster gastrointestinal recovery, lower inflammatory response, short time of hospital stay and fewer complications. Despite these encouraging findings, more studies are needed to prove causation and derive specific dietary recommendations for the clinical setting, particularly randomized controlled trials.
