Factors influencing disease recurrence after ileocolic resection in adult and pediatric onset Crohn's disease

BackgroundFactors influencing recurrence of ileocecal Crohn's disease (CD) after surgical resection may differ between adolescents and adults.MethodsCD patients who underwent ileocecectomy were retrospectively divided into pediatric onset (age at diagnosis ≤ 16 years, n = 34) and adult onset (>16, n = 108) patients to evaluate differences in risks of endoscopic and clinical recurrence.ResultsIn 142 patients, rates of any recurrence, endoscopic recurrence, and clinical recurrence at 5 years were 78%, 88%, and 65%, respectively. Risks of recurrence were similar between groups. Younger patients were more likely to be on immunologics preoperatively and more likely to be started on immunoprophylaxis postoperatively. Immediate postoperative prophylaxis was predictive of delayed clinical recurrence only in the older group.ConclusionsDespite increased preoperative and postoperative immunoprophylaxis in younger patients, recurrence rates of CD after ileocecectomy do not differ between these groups. Immediate postoperative prophylaxis was predictive of delayed clinical recurrence only in patients with adult onset CD.
