Outcomes of Primary Ileocolic Resection for Pediatric Crohn Disease in the Biologic Era

ABSTRACT Objectives: Current clinical algorithms position surgery as the last option in pediatric Crohn disease (CD). Studies suggest improved outcomes with earlier surgery, but pediatric postoperative outcomes data in the biologic era are limited. We aimed to describe the preoperative management and postoperative outcomes in a pediatric CD cohort who underwent ileocolic resection (ICR) at a tertiary care inflammatory bowel disease center over the last decade. Methods: Single‐center, retrospective study of pediatric (i2) at 2 years post‐ICR. Key secondary outcomes included endoscopic remission (Rutgeerts’ i0), frequency of 30‐day postoperative complications, anthropometric changes, and histologic recurrence. Uni‐ and multivariable analyses examined associations of clinical/laboratory characteristics with endoscopic recurrence. Factors predictive of 30‐day complications were also analyzed. Results: Seventy‐eight children underwent ICR a median of 17.8 months (interquartile range [IQR] 2.6–53.9) from diagnosis. Median age at diagnosis and surgery was 13.8 (11.1–16.7) and 16.8 years (15.1–17.8), respectively. In the 41 patients with >1 post‐operative endoscopy, the rate of endoscopic recurrence was 46% at 2 years (median time to recurrence: 10 [7–20] months). Histologic recurrence was present in 44% in endoscopic remission (κ = 0.11, P = 0.53). Endoscopic recurrence was associated with younger age at diagnosis and longer disease duration. 30‐day complications occurred at a rate of 18%; only 1% experienced severe complications. All anthropometric measures significantly improved after surgery. Conclusions: Given the inherent risk of postoperative recurrence associated with age and disease duration, children would benefit from postoperative surveillance and effective prophylaxis.
