Gastroenteric inflammation in children with ulcerative colitis

This is a retrospective review of five pediatric cases of inflammatory bowel disease with gastroduodenal as well as pancolonic inflammation. The presumptive diagnosis was Crohn's disease in all. Three of five also had microscopic ileitis. Chronic active gastritis was present at diagnosis in all five and duodenitis in four of five. None ever had noncaseating granulomas in any location. Prolonged (mean, 22 months) and ineffective trials of multiple medical therapies were carried out before subtotal proctocolectomy, which allowed the diagnosis of ulcerative colitis to be made in all children. Surgery remained curative after follow-up of over 1 yr (mean, 16 months). This experience confirms that gastrodnodenal inflammation occurs in children with ulcerative colitis. Presence of gastroduodenal inflammation does not ensure the diagnosis of Crohn's unless other characteristic features of Crohn's are present. Accurate discrimination between Crohn's and ulcerative colitis remains important in management of pediatric inflammatory bowel disease to facilitate timely surgical referral. Upper gastrointestinal tract inflammation in ulcerative colitis warrants further study.
