Risk Factors for Surgery in Pediatric Patients with Crohn's Disease.

<bold>Objective: </bold>Pediatric Crohn's disease (CD) has a more aggressive phenotype and course than in adults. Many patients develop complications that require surgery. The aim of this study was to identify the factors associated with increased risk for surgical intervention in pediatric patients with CD.<bold>Subjects and Methods: </bold>This study is a retrospective review of medical records. We analyzed the following variables: sex, age at diagnosis, presenting symptoms, duration of symptoms before diagnosis, disease location and severity, the presence of extraintestinal manifestations, and the presence of anti-Saccharomyces cerevisiae antibodies. Univariate analysis using the Mann-Whitney test and Fisher's exact test was performed to detect the factors associated with surgery. Potential risk factors with p < 0.05 were further analyzed using a multivariate binary logistic regression model.<bold>Results: </bold>Fifty-seven patients (27 girls and 30 boys) were included in the analysis. More than one-fourth of them (28.1%) required surgical management. Female sex (p = 0.043), disease behavior (p = 0.012), and the presence of perianal disease at diagnosis (p < 0.001) were the variables associated with surgical intervention. Stricturing disease (B2) (odds ratio [OR], 24.944; p = 0.016), stricturing and penetrating disease (B2B3) (OR, 28.276; p = 0.011), and the presence of perianal disease at diagnosis (OR, 95.802; p = 0.001) were independent risk factors for surgery. Female sex was associated with surgery without being an independent risk factor.<bold>Conclusion: </bold>Females with B2 or B2B3 or the presence of perianal disease at diagnosis are at a higher risk for surgery and should be considered for more aggressive medical treatments.
