Long-term outcome after first intestinal resection in pediatric-onset Crohn's disease: a population-based study

Background: To describe long-term postoperative evolution of pediatric-onset Crohn's disease (CD) and identify predictors of outcome we studied a population-based cohort (1988–2004) of 404 patients (0–17 years), of which 130 underwent surgery. Methods: Risks for a second resection and first need for immunosuppressors (IS) and/or biologics were estimated by survival analysis and Cox models used to determine predictors of outcome. Impact of time of first surgery on nutritional catch-up was studied using regression. Results: In all, 130 patients (70 females) with a median age at diagnosis of 14.2 years (interquartile range: 12–16) were followed for 13 years (9.4–16.6). Probability of a second resection was 8%, 17%, and 29% at 2, 5, and 10 years, respectively. In multivariate analysis, age
