Background: There is limited evidence on the long-term outcome of intestinal resection in pediatric-onset Crohn's disease (POCD) with no established predictors of adverse outcomes. We aimed to investigate clinical outcomes and predictors for adverse outcome following intestinal resection in POCD. Methods: The medical records of patients with POCD who underwent at least 1 intestinal resection between 1990 and 2014 were reviewed retrospectively. Main outcome measures included time to first flare, hospitalization, second intestinal resection, and response to nonprophylactic biologic therapy. Results: Overall, 121 patients were included. Median follow-up was 6 years (range 1-23.6). One hundred and seven (88%) patients experienced at least 1 postsurgical exacerbation, 52 (43%) were hospitalized, and 17 (14%) underwent second intestinal resection. Of 91 patients who underwent surgery after the year 2000, 37 (41%) were treated with antitumor necrosis factor α (anti-TNFα) (nonprophylactic) following intestinal resection. Time to hospitalization and to second intestinal resection were shorter among patients with extraintestinal manifestations (EIMs) (HR 2.7, P = 0.006 and HR = 3.1, P = 0.03, respectively). Time to initiation of biologic treatment was shorter in patients with granulomas (HR 2.1, P = 0.038), whereas being naive to anti-TNFα treatment before surgery was a protective factor for biologic treatment following surgery (HR 0.3, P = 0.005). Undergoing intestinal resection beyond the year 2000 was associated with shorter time to first flare (HR 1.9, P = 0.019) and hospitalization (HR 2.6, P = 0.028). Conclusion: Long-term risk for flares, hospitalization, or biologic treatment is significant in POCD following bowel resection. EIMs increase the risk for hospitalization and second intestinal resection.
