Up to 24% of elementary and middle school students and 17% of high school students experience persistent weekly abdominal pain.1,2 Chronic abdominal pain accounts for approximately 4% of pediatric office visits.1 Most children with chronic abdominal pain have functional abdominal pain disorders, characterized by pain with or without other gastrointestinal symptoms that is not attributable to another medical condition. Of remaining patients with an identifiable medical condition, their pain is likely the result of inflammation with or without infection, anatomic problem (e.g., choledochal cyst, recurrent volvulus), gastrointestinal motility disorder, metabolic disorder, late effect of trauma, or a neoplastic process involving a lower thoracic or abdominal organ. This chapter focuses on identifying, evaluating and treating conditions causing chronic abdominal pain, with emphasis on those causes related to infectious diseases.
