Abstract

SummaryBackgroundEarly complicated Crohn's disease (CD) may require ileal resection as first‐line treatment.AimTo evaluate the long‐term outcomes of patients who underwent early ileal resection.MethodsWe conducted a retrospective study in two inflammatory bowel diseases (IBD) referral centres, including patients with ileocaecal resection and segmental ileal resection within 5 years of CD diagnosis. Early resection was defined as within 6 months of diagnosis, intermediate resection between 6 months and 2 years, and late resection between 2 and 5 years. The primary outcome was the cumulative risk of a second ileal surgery. Secondary outcomes included the use of postoperative treatments and morphological recurrence after initial surgery (Rutgeerts score ≥i2, or recurrence on imaging).ResultsAmong 393 patients who underwent ileal resection within 5 years of diagnosis, 130, 128 and 135, respectively, had early, intermediate and late resection. The cumulative risk of second surgery at 10 years was not significantly different in the early resection group (25.0% [95% CI 17.4–35.2]), than the intermediate (16.8% [95% CI 10.5–26.2]; p = 0.17) or late resection group (22.7% [95% CI 15.1–33.3]; p = 0.83). The early resection group required fewer postoperative treatments than the late resection group with median survivals without treatments of 3.7 and 0.9 years, respectively (p = 0.002). Patients who had early resection had significantly less morphological recurrence than the late resection group (p = 0.02).ConclusionEarly ileal resection in CD is not associated with a higher risk of a second resection. It may be associated with reduced use of medical treatments and fewer morphological recurrences.
