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.


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.


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 <14, stenosing (B2) and penetrating (B3) behaviors and upper gastrointestinal location (L4) at diagnosis were associated with an increased risk of second resection. Probability of receiving IS or biologics was 18%, 34%, and 47% at 2, 5, and 10 years, respectively. In multivariate analysis, L4 was a risk factor for requiring IS or biologics, while surgery within 3 years after CD diagnosis was protective. Catch-up in height and weight was better in patients who underwent surgery within 3 years after CD diagnosis than those operated on later.


In this pediatric-onset CD study, mostly performed in a prebiologic era, a first surgery performed within 3 years after CD diagnosis was associated with a reduced need for IS and biologics and a better catch-up in height and weight compared to later surgery.
