Prolonged constant rate elemental enteral nutrition in Crohn's disease.

Constant rate enteral nutrition (CREN) has been used in 17 pediatric patients with Crohn's disease. Exclusive CREN was maintained from 2 to 7 months and progressively reduced to assure fractioned oral intakes from 12 to 22 months. From this preliminary study, CREN appeared to be as effective as steroid therapy in initiating remission of active Crohn's disease and was able to suppress steroid dependence. In some cases with prolonged CREN, reduction or disappearance of stenotic lesions of the bowel was observed. Two other positive points must be emphasized: the favorable psychological impact of the method and the ability to avoid growth suppression secondary to steroids. The long-term effects and longer remissions must be confirmed by a multicenter study in a larger group of patients.
