Rationale: Nutrition-related conditions are prevalent in IBD, especially 6 months preoperatively, adversely impact postoperative outcomes and are potentially reversible with nutritional interventions. In this study, we aim to comprehensively review current preoperative nutritional assessment practices in IBD patients.
Methods: This systematic review (PROSPERO registration number CRD420251153038) included PubMed, Embase, and Scopus studies from inception to November 6, 2025. Retrospective and prospective cohort studies in adult patients with IBD [Crohn’s disease (CD), ulcerative colitis (UC)] undergoing elective or emergency surgery were included if preoperative nutritional screening/assessment was performed within 6 months before surgery.
Results: Of 3,611 studies identified, 31 were included. Nutritional risk was assessed in 15 studies, most commonly using the Prognostic Nutritional Index, NRS-2002, or MUST. Nutritional risk was present in 28.3-87.7% of the patients with CD and in 17.3-81.3% of those with UC. Malnutrition was reported in 12 studies (CD: 21.5-34.2%; UC: 21-62.5%). Only 1 study used GLIM criteria; the remainder applied various definitions (%weight loss, BMI, albumin levels, or combinations thereof). Hypoalbuminemia was included in 7/12 studies, with no variation by year or region. Among the 11 studies reporting sarcopenia prevalence (CD:19.6-70.4%; UC: 37.5-59.4%), 10 assessed muscle mass using an imaging method. Myosteatosis was measured in 3 studies among CD patients. All studies examined the association between nutritional status and postoperative outcomes.

Conclusion: Considerable heterogeneity exists in nutritional assessment in surgical IBD patients. A pooled analysis stratified by nutrition-related conditions is planned to better quantify the prevalence of each condition and its respective impact on postoperative outcomes.
