The pediatric corner: the varied manifestations of Crohn's disease in children and adolescents.

: Thirty children less than 15 years of age with Crohn's disease are reported. The mean age of onset was nine years and five months. Delay in diagnosis may stem from the varying modes of presentation. The mean delay in diagnosis was two years. Chronic diarrhea and/or recurrent abdominal pain associated with extraintestinal manifestations, particularly abnormalities of growth and development suggests the possibility of Crohn's disease in the pediatric age group. Involvement of the terminal ileum occurred in 29 of the 30 patients. In addition, colonic disease occurred in 13 and jejunal involvement in one. Four patients presented with an acute onset of their disease. A favorable response to either medical or surgical therapy occurred in all four. Twenty-six patients had an insidious onset and tended to have a chronic course despite either medical and/or surgical therapy. Thirteen patients had an intestinal resection, with recurrence occurring in three from 1-4 years postoperatively. To date there has been one death.
