Summary
Crohn's disease patients undergoing bowel resection have significant re-resection rates, influenced by disease activity and phenotype. Early biologic therapy shows promise in reducing re-resection risk for specific Crohn's disease subgroups.
Area of Science:
- Gastroenterology
- Surgical Oncology
- Clinical Epidemiology
Background:
- Crohn's disease (CD) management often necessitates bowel resection, despite medical advances.
- Post-resection recurrence and re-resection remain significant challenges for CD patients.
Purpose of the Study:
- To determine contemporary re-resection rates in Crohn's disease patients.
- To identify factors influencing re-resection and disease modification.
Main Methods:
- Retrospective, population-based cohort study of 631 Danish CD patients undergoing primary resection (2010-2020).
- Individual patient-level data analysis to assess re-resection rates and risk factors.
Main Results:
- 24.5% of patients had a second resection, 5.3% a third; 1, 5, and 10-year re-resection rates were 12.6%, 22.4%, and 32.2%.
- Disease activity and stoma reversal were primary reasons for re-resection.
- Early biologic therapy (within 1 year) reduced re-resection risk for stenotic/penetrating phenotypes (HR 0.58).
- Risk factors included resected segment location, disease location/behavior, smoking, and perianal disease.
Conclusions:
- Re-resection rates are lower than previously reported and linked to CD phenotype and location.
- Biologic therapy initiated within a year post-resection may modify disease course in specific CD patient subgroups.

Introduction
Inflammatory bowel disease, commonly known as IBD, refers to a collection of disorders that lead to persistent inflammation of the gastrointestinal tract. The two types of IBD are ulcerative colitis, which impacts the colon, and Crohn's disease, which can involve any part of the gastrointestinal segment.

Surgical interventions for inflammatory bowel disease (IBD), which includes ulcerative colitis and Crohn's disease, are essential in managing symptoms and addressing complications. The selection of surgical procedures is contingent upon the specific conditions and complications that stem from these illnesses.
