Some children with intussusception may resolve spontaneously, but it is important to closely monitor their condition with ultrasound to understand the status of the intussusception. If it does not resolve on its own in a short period, immediate surgical treatment is necessary. If the ultrasound shows successful resolution, or if the child's clinical symptoms such as vomiting and abdominal pain improve and the ultrasound does not reveal any obvious abnormalities, it is considered an automatic recovery.
