Management and prevention of postoperative Crohnʼs disease

Postoperative Crohn's disease (CD) recurrence is a common occurrence after intestinal resection. Currently, the optimal management of patients who have undergone surgical resection is unknown and treatment remains subjective. Clinicians in conjunction with patients must balance the risks of recurrence against the potential risks associated with treatment. For those at very low risk of recurrence, no therapy may be needed; however, for patients at moderate risk immunomodulators should be considered. For those at highest risk of recurrence, biologic therapy, specifically antitumor necrosis factor agents, have emerged as appropriate treatment. Any postoperative management strategy should include a colonoscopy 6-12 months after surgery to identify recurrence. This review discusses current evidence for various pharmacologic approaches in the prevention of postoperative recurrence and provides guidance for clarifying patient risk.
