Objective To conduct a scoping review of existing research on nutritional pre-rehabilitation for patients undergoing colo-rectal cancer surgery, in order to provide a valuable reference for developing an effective nutritional pre-rehabilitation plan specifi-cally tailored to these patients. Methods Employing the Australian JBI Evidence-based Health Centre Scope Review Guidelines as the methodological framework, a systematic search was conducted in PubMed, Embase, Cochrane Library, Web of Science, CINAHL, CBM, CNKI, WanFang Data and VIP network. The relevant studies on nutritional pre-rehabilitation of patients undergoing colorectal cancer surgery were collected, and covering the period from database establishmentuntil April 2024. Two researchers independently performed literature screening and data extraction. Results A total of 11 studies were included, covering nutritional risk assessment tools, specific intervention measures, timing and location of interventions, outcome indicators for interventions, and the actual effects of intervention in nutritional pre-rehabilitation for patients undergoing colorectal cancer surgery. Conclusion Nutritional pre-rehabilitation intervention is both practical and effective for patients undergoing colorectal cancer surgery. However, there remains considerable variability in specific intervention measures and outcome indicators, necessitating further evidence to establish an optimal nutritional pre-rehabilitation strategy.
