    BackgroundEarly endoscopic evaluation is recommended for assessment of postoperative recurrence (POR) of Crohn's disease (CD) but no further monitoring recommendations are available.AimTo evaluate the long-term outcome of patients without endoscopic POR at first endoscopic assessment.MethodsRetrospective four-centre study including consecutive CD patients with ileocolonic resection (ICR) without endoscopic POR (Rutgeerts score i0-i1) at first endoscopic assessment performed within 18 months from ICR. All patients had a clinical follow-up ≥24 months and at least one further endoscopic assessment. Main outcomes were endoscopic, clinical and surgical POR, need for rescue therapy and "delayed POR" (any need for rescue therapy or clinical or surgical POR) during follow-up.ResultsOverall, 183 patients were included (79% with risk factors for POR, 44% without postoperative prophylaxis). Endoscopic POR was observed in 42% of patients. Clinical POR-free survival was 89.4% and 81.5% at 3 and 5 years, and delayed POR-free survival was 76.9% and 63.4% at 5 and 10 years, respectively. In multivariate analysis, postoperative prophylaxis (HR .55; 95% CI .325-.942) and active smoking (HR 1.72; 95%CI 1.003-2.962) were independent risk factors for clinical POR, whereas presence of mild endoscopic lesions at index ileocolonoscopy (i1) was the only risk factor for delayed POR (HR 1.824; 95% CI 1.108-3.002).ConclusionsLong-term risk of POR among patients with no or mild endoscopic lesions at first ileocolonoscopy after surgery is steadily low, being higher among smokers, in the absence of postoperative prophylaxis and when mild endoscopic lesions are observed in the first endoscopic assessment.© 2024 Stichting European Society for Clinical Investigation Journal Foundation.
