Once intussusception occurs, only a small portion of the small intestinal intussusception can reduce on its own. Those occurring in the colon or where re-intussusception occurs generally cannot reduce spontaneously and require enema therapy or surgical treatment. Enema therapy refers to cases where the intussusception occurs within forty-eight hours, the overall condition is good, there is no abdominal distension, no obvious dehydration or electrolyte disorders, and air or barium enema can be used. If the condition persists for more than forty-eight hours, the overall condition is poor, with symptoms such as dehydration, lethargy, high fever, shock, significant abdominal distension, signs of peritoneal irritation, multiple occurrences of intussusception, prior organic changes, or situations requiring surgical treatment for small bowel intussusception.
