Background: We aimed to prospectively assess whether endoscopic recurrence severity at 1 year in Crohn's disease is predictive of clinical recurrence within 5 years. Methods: Clinical recurrence (Crohn's Disease Activity Index > 150) was assessed yearly for 5 years in Crohn's disease patients undergoing ileo-colonic resection. At 1 year, recurrence was assessed by colonoscopy (Rutgeerts' score ≥i1 or ≥2i) and small intestine contrast ultrasonography. Results: 40 patients were included (23 males, median age 39 [16-69] years). Clinical recurrence occurred within 5 years in 16 (40%) patients (years 1, 2, 3, 4, 5: 2 [5%]; 10 [25%]; 4 [10%]; 2 [5%]; 4 [10%], respectively). At 1 year, endoscopic recurrence (score ≥ i1) occurred in 39 (97.5%) patients (score ≥ i2: 33 [82.5%]). Ultrasound detected lesions compatible with recurrence in 39/40 (97.5%) patients. Endoscopic score at 1 year was correlated with clinical score at 2 years (p = 0.007; r = 0.41). Endoscopic score at 1 year was higher in patients with (n = 10) vs without (n = 30) clinical recurrence at 2 years (3 [2-4] vs 2 [0-4]; p = 0.003). Higher endoscopic score (>i2) at 1 year was a risk factor for clinical recurrence within 5 years (OR = 0.18; 95% CI 0.04-0.71; p = 0.008). Conclusions: In Crohn's disease, severity of endoscopic recurrence at 1 year remains a predictive marker of clinical recurrence within 5 years. Small intestine contrast ultrasonography is useful for assessing 1-year recurrence.

Abstract

Background: We aimed to prospectively assess whether endoscopic recurrence severity at 1 year in Crohn's disease is predictive of clinical recurrence within 5 years. Methods: Clinical recurrence (Crohn's Disease Activity Index > 150) was assessed yearly for 5 years in Crohn's disease patients undergoing ileo-colonic resection. At 1 year, recurrence was assessed by colonoscopy (Rutgeerts' score ≥i1 or ≥2i) and small intestine contrast ultrasonography. Results: 40 patients were included (23 males, median age 39 [16-69] years). Clinical recurrence occurred within 5 years in 16 (40%) patients (years 1, 2, 3, 4, 5: 2 [5%]; 10 [25%]; 4 [10%]; 2 [5%]; 4 [10%], respectively). At 1 year, endoscopic recurrence (score ≥ i1) occurred in 39 (97.5%) patients (score ≥ i2: 33 [82.5%]). Ultrasound detected lesions compatible with recurrence in 39/40 (97.5%) patients. Endoscopic score at 1 year was correlated with clinical score at 2 years (p = 0.007; r = 0.41). Endoscopic score at 1 year was higher in patients with (n = 10) vs without (n = 30) clinical recurrence at 2 years (3 [2-4] vs 2 [0-4]; p = 0.003). Higher endoscopic score (>i2) at 1 year was a risk factor for clinical recurrence within 5 years (OR = 0.18; 95% CI 0.04-0.71; p = 0.008). Conclusions: In Crohn's disease, severity of endoscopic recurrence at 1 year remains a predictive marker of clinical recurrence within 5 years. Small intestine contrast ultrasonography is useful for assessing 1-year recurrence.
