N2 - BACKGROUND: The advantage of early ileocecal resection after Crohn's disease diagnosis is a matter of debate. This study aims to assess the timing of ileocecal resection on prognosis, after correction for possible confounders. METHODS: Patients with Crohn's disease with primary ileocecal resection between 2000 and 2019 were included in a retrospective multicentre cohort. The primary endpoint was endoscopic recurrence (Rutgeerts score =i2b) within 18 months. Secondary endpoints were escalation of inflammatory bowel disease medication within 18 months and re-resection during follow-up. The association between timing of ileocecal resection and these endpoints was investigated using multivariable proportional hazard models, corrected for covariates including Montreal classification, postoperative prophylaxis, smoking, indication for surgery, medication before ileocecal resection, perianal fistulas, surgical approach, histology, length of resected segment and calendar year. RESULTS: In 822 patients ileocecal resection was performed after a median of 3.1 years (i.q.r. 0.7-8.0) after Crohn's disease diagnosis. The lowest incidence of endoscopic recurrence, escalation of inflammatory bowel disease medication and re-resection was observed for patients undergoing ileocecal resection shortly after diagnosis (0-1 months). After correction for covariates, patients with ileocecal resection at 0, 4 and 12 months after diagnosis had a cumulative incidence of 35 per cent, 48 per cent and 39 per cent for endoscopic recurrence, 20 per cent, 29 per cent and 28 per cent for escalation of inflammatory bowel disease medication and 20 per cent, 30 per cent and 34 per cent for re-resection, respectively. In the multivariable model ileocolonic disease (HR 1.39 (95 per cent c.i. 1.05 to 1.86)), microscopic inflammation of proximal and distal resection margins (HR 2.20 (95 per cent c.i. 1.21 to 3.87)) and postoperative prophylactic biological and immunomodulator (HR 0.16 (95 per cent c.i. 0.05 to 0.43)) were associated with endoscopic recurrence. CONCLUSION: The timing of ileocecal resection was not associated with a change of disease course; in the multivariable model, the postoperative recurrence was not affected by timing of ileocecal resection.
