Inflammatory Bowel Disease: Perioperative Pharmacological Considerations

The perioperative management of patients with inflammatory bowel disease is challenging given the altered immune system that results from a variety of biologic and immunomodulator therapies. Clinicians are often faced with challenges and complicated equations when deciding on the type and dose of medication. To understand the effect of these medications and review the evidence regarding the management of these medications in the perioperative setting, a PubMed-based literature search (January 1, 1960, through April 1, 2011) was conducted using the following search terms: perioperative management, risk, outcome, inflammatory bowel disease, ulcerative colitis, Crohn's disease, aminosalicylates, glucocorticoids, purine analogues, cyclosporine, methotrexate, biologic therapy, infliximab, and thromboembolism. The 414 articles identified were manually sorted to exclude those that did not address perioperative risk, outcomes, and medications in the abstracts, yielding 84 articles for review. Additional references were obtained from the citations within the retrieved articles. This review surveys the findings of the selected articles and presents guidelines and resources for perioperative medication management for patients with inflammatory bowel disease undergoing surgery.
