Diarrheal diseases are among the leading causes of morbidity and mortality in children worldwide, causing 1 billion episodes of illness and 3-5 million deaths annually. In the United States, 20-35 million episodes of diarrhea occur each year in the 16.5 million children who are younger than 5 years, resulting in 300-400 deaths.

Medical treatment fails in 20% of patients who have NEC with pneumatosis intestinalis at diagnosis, resulting in a 9-25% mortality. The mortality of NEC is higher than 50% in infants with birth weights lower than 1000 g.

About 70% children with UC enter remission within 3 months of initial therapy, and 50% remain in remission over the next year. Colectomy within 5 years is required in as many as 26% of children who present with severe disease compared with less than 10% of those who present with mild disease. Approximately 70% of children with CD require surgery within 10-20 years after the diagnosis.
