Abdominal ultrasound examination should be performed in each case of abdominal pain symptoms reported by the child, especially if the pain is accompanied by chronic constipation, diarrhea and fever. Frequent attacks of colic occurring in newborns and infants, regardless of the type of food consumed, are a disturbing symptom. It is worth noting that some diseases, and even tumors of the abdominal cavity initially do not have to show clear symptoms. Ultrasound screening allows the early detection of these abnormalities in children, greatly increasing the chances of a successful cure.
