Abdominal Pain in Children: From the Eternal City to the Examination Room.

Abdominal pain is a common presenting symptom in children. The differential diagnosis of abdominal pain is extensive; however, a vast majority of patients ultimately are diagnosed with functional abdominal pain disorders. Functional gastrointestinal disorders are defined using the recently released Rome IV criteria. These are not diagnoses of exclusion. If there are no alarm signs, the diagnosis may be made with a focused evaluation. Treatment of these disorders requires a biopsychosocial approach to the disorder and an individualized and multipronged treatment plan.
