The terminal ileum is involved in 50-70% of children. More than half of these patients also have inflammation in various segments of the colon, usually the ascending colon. Gastric inflammation, duodenal inflammation, or both may be observed in as many as 30-40% of children with Crohn disease. The primary pancreatic manifestation is pancreatitis.
