Abstract
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 ɑ (anti-TNFɑ) (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 naïve to anti-TNFɑ 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.
