| Background and Aims: No consensus exists on optimal strategy to prevent postoperative recurrence [POR] after ileocaecal resection [ICR] for Crohn's disease [CD]. We compared early medical prophylaxis versus expectant management with treatment driven by findings at elective endoscopy 6-12 months after ICR. Methods: A retrospective, multicentric, observational study was performed. CD patients undergoing first ICR were assigned to Cohort 1 if a biologic or immunomodulator was [re]started prophylactically after ICR, or to Cohort 2 if no postoperative prophylaxis was given and treatment was started as reaction to elective endoscopic findings. Primary endpoint was rate of endoscopic POR [Rutgeerts >i1]. Secondary endpoints were severe endoscopic POR [Rutgeerts i3/i4], clinical POR, surgical POR, and treatment burden during follow-up. Results: Of 346 included patients, 47.4% received prophylactic postoperative treatment [proactive/Cohort 1] and 52.6% did not [reactive/Cohort 2]. Endoscopic POR [Rutgeerts >i1] rate was significantly higher in Cohort 2 [41.5% vs 53.8%, OR 1.81, p = 0.039] at endoscopy 6-12 months after surgery. No significant difference in severe endoscopic POR was found [OR 1.29, p = 0.517]. Cohort 2 had significantly higher clinical POR rates [17.7% vs 35.7%, OR 3.05, p = 0.002] and numerically higher surgical recurrence rates [6.7% vs 13.2%, OR 2.59, p = 0.051]. Cox proportional hazards regression analysis showed no significant difference in time to surgical POR of proactive versus expectant/reactive approach [HR 2.50, p = 0.057]. Quasi-Poisson regression revealed a significantly lower treatment burden for immunomodulator use in Cohort 2 [mean ratio 0.53, p = 0.002], but no difference in burden of biologics or combination treatment. Conclusions: The PORCSE study showed lower rates of endoscopic POR with early postoperative medical treatment compared with expectant management after first ileocaecal resection for Crohn's disease. |
