This study aimed to explore the effect of enteral nutrition support, based on the rapid rehabilitation surgery concept, on the postoperative recovery and nutritional status of elderly patients with colorectal cancer. One hundred patients who underwent radical laparoscopic surgery for colorectal cancer in our department from January 2021 to December 2022 were included. Traditional nursing measures were adopted for patients in the control group, while early enteral nutrition support based on accelerated rehabilitation surgery was provided to patients in the observation group. Our findings revealed that the time to get out of bed, exhaust, defecate, have the first feeding, and hospital stay was shorter in the observation group than in the control group (P < 0.05). Following nursing, the occurrence of complications, serum C-reactive protein levels, and lymphocyte count decreased (P < 0.05), while the nutritional and immune indexes, as well as SF-36 scores increased (P < 0.05) in the observation group compared to the control group. Our results suggested that early enteral nutrition support based on rapid rehabilitation surgery can significantly improve the nutritional and immune indexes of patients undergoing colorectal cancer surgery and has good clinical efficacy.
