Objectives: Data describing the incidence and risk factors for colectomy in pediatric ulcerative colitis (UC) is inconsistent. Our aim was to describe the colectomy rate and to identify risk factors associated with colectomy in a large cohort of children with UC with long-term follow-up. Materials and Methods: We performed a retrospective chart review of pediatric UC cases that were diagnosed at Schneider Children's Medical Center of Israel between 1981 and 2013. Potential predictors for colectomy including age at diagnosis, sex, disease extent, severity indices, and different therapeutic regimens during disease course were assessed. Results: Of 188 patients with pediatric onset UC, 34 (18%) underwent colectomy. Median follow-up was 6.9 years (range, 1-30). Kaplan-Meier survival estimates of the cumulative probability for colectomy were 4% at 1 year and 17% at 10 years from diagnosis. Multivariate Cox models showed that male sex (hazard ratio 4.2, P = 0.001) and severe disease at diagnosis reflected by Pediatric Ulcerative Colitis Activity Index score ≥65 (hazard ratio 8.9, P < 0.001) were associated with increased risk for colectomy. Age, disease extent, ethnicity, family history of inflammatory bowel disease, early introduction of immunomodulators, or treatment with antitumor necrosis factor α agent did not affect the risk of colectomy. Conclusions: Male sex and higher Pediatric Ulcerative Colitis Activity Index score at diagnosis are independent risk factors for colectomy.
