Pediatric intussusception is most commonly seen in children under 2 years of age, most often in the first 6-10 months of life, with the incidence decreasing as the age of the disease increases. The cause of the disease is unknown, but it is thought to be related to infection, mostly manifesting as abdominal pain, abdominal masses and blood in the stool, while infants and children may present with paroxysmal crying and restlessness. If a child cries at night and has blood in the stool, attention should be paid to exclude the disease. For intussusception, abdominal ultrasound can be used for diagnosis. Air enema repositioning is preferred for the treatment of this disease, or water repositioning can be done under ultrasound positioning. If the symptoms appear for more than 48 hours and the air enema reset fails, surgery is required, which can be divided into intussusception or partial bowel resection.
