    Abstract:
    INTRODUCTION: The incidence of endoscopic recurrence (ER) in Crohn's disease following curative resection is up to 75% at 1 year. Endoscopy is the most sensitive method to detect the earliest mucosal changes and the severe ER at 1 year seems to predict a clinical relapse. METHODS: The aim of this prospective study was to evaluate the incidence of early ER 6 months after curative resection. Secondary outcome was to evaluate the role of 5-aminosalicylic acid (5-ASA) in the prevention of ER at 6 months. A total of 170 patients were included in the study. They were carried-out from the evaluation of the appearance of ER during a trial performed to assess the role of azathioprine vs. 5-ASA as early treatment of severe ER. All the patients started 5-ASA treatment 2 weeks after surgery. RESULTS: Six months after surgery ER was observed in 105 patients (62%). The endoscopic score was reported as severe in 78.1% of them (82 out of 105). At univariable analysis only ileo-colonic disease influenced the final outcome associating to a lower risk of severe ER (p=0.04; OR 0.52, 95% CI 0.277-0.974). CONCLUSION: In this prospective Italian multicenter IG-IBD study a great proportion of ER occur within 6 months from ileo-colonic resection, with a significant rate of severe ER. Furthermore this study confirms the marginal role of 5-ASA in the prevention of ER. This suggests that post-surgical endoscopic evaluation should be performed at 6 months instead of 1 year to allow an adequate early treatment.
