Enteral nutrition for maintenance of remission in Crohn's disease.

Prevention of relapse is a major issue in the management of Crohn's disease. Corticosteroids and 5-ASA preparations are not effective for the maintenance of remission. Methotrexate, infliximab, 6-mercaptopurine and its prodrug, azathioprine may be effective in maintaining remission, but these drugs may cause significant adverse events.
