Optimizing Biologic Therapy for the Prevention of Post-Operative Recurrence in Crohn’s Disease: Current Evidence and Future Perspectives

Crohn’s disease (CD) imposes a substantial burden on patients due to its chronic, relapsing nature, often necessitating surgical intervention. However, surgery is not curative, and post-operative recurrence (POR) remains a major clinical challenge, with up to 80% of patients developing endoscopic recurrence within one year if left untreated. The pathophysiology of POR is multifactorial, involving dysregulated immune responses, gut microbiota alterations, and mucosal healing impairment, highlighting the need for targeted therapeutic strategies. This review aims to explore the current landscape of POR management, focusing on biologic therapies and emerging advanced treatments. Conventional management relies on early prophylactic therapy with anti-TNF agents such as infliximab and adalimumab, which have demonstrated efficacy in reducing endoscopic and clinical recurrence. However, newer biologics, including IL-23 inhibitors (risankizumab) and Janus kinase (JAK) inhibitors (upadacitinib), have shown promise in CD management, though their role in POR remains underexplored. The lack of direct clinical evidence for advanced biologics in POR prevention, combined with inter-individual variability in treatment response, underscores the need for further research. Future directions should focus on optimizing therapeutic strategies through personalized medicine, identifying predictive biomarkers, and conducting robust trials to establish the efficacy of novel agents in POR prevention. A tailored, evidence-driven approach is essential to improving long-term outcomes and minimizing disease recurrence in post-operative CD patients.
