Management of Crohn’s Disease in Adult Patients: A Contemporary Surgical Perspective

Introduction: Crohn’s disease (CD) remains associated with long-term morbidity despite biologic therapies. Surgery, historically considered a last-resort option, is increasingly integrated into disease management earlier. This review examines the evolving role of surgery in the biologic era. Methods: A focused narrative review of randomized controlled trials, meta-analyses, observational studies, and international guidelines addressing contemporary surgical strategies in CD was performed. Results: The LIR!C trial demonstrated that early ileocecal resection provides durable remission and improves long-term outcomes compared with biologic therapy in selected patients. The PISA II trial supported an early combined surgical and medical approach for perianal fistulizing disease. Preoperative optimization, including nutritional support and adjustment of immunosuppressive therapy, has become a cornerstone of perioperative management. Laparoscopic surgery remains the preferred approach whenever feasible, while robotic surgery is emerging as a promising platform that is expected to play an increasingly important role in the surgical management of CD. Postoperative recurrence remains a major challenge, prompting the development of innovative surgical strategies. Although the Kono-S anastomosis initially showed promising reductions in recurrence, recent prospective studies failed to confirm superiority over conventional techniques. Similarly, extended mesenteric excision did not demonstrate improved outcomes despite increasing evidence implicating the mesentery in CD pathogenesis. Strictureplasty remains an effective option for selected fibrotic small-bowel strictures. Conclusions: Surgery remains central to multidisciplinary CD management and offers the potential to modify disease when performed early in selected patients. The impact of innovative surgical strategies on postoperative recurrence remains uncertain, and ongoing trials are expected to further help with surgical decision-making.
