The causes of intussusception are divided into primary and secondary types, with 95% being primary, commonly seen in infants and young children. In infants, the mesentery of the ileocecal area is not yet fully fixed and has greater mobility, which is a structural factor prone to intussusception. Secondary cases account for 5%, where intussusception occurs. Some intestines show clear organic changes, such as Meckel's diverticulum, intestinal polyps, intestinal tumors, intestinal duplication anomalies, abdominal purpura, and thickening of the intestinal wall, which can cause intussusception of the intestines. Certain triggers, including dietary changes, viral infections, and diarrhea, can induce intussusception.
