Intussusception in children is a common surgical condition. The treatment approach depends on the severity of the child's clinical symptoms. If the intestines have not been telescoped for long, and the intestinal mucosa has not suffered ischemic necrosis, and if the clinical symptoms are mild, air enema can be used to relieve the intussusception without the need for surgery. However, if the clinical symptoms are severe and necrosis has been prolonged, meaning the intestinal mucosa has reached a state of ischemia and necrosis that is irreparable, surgical treatment in a surgical setting is definitely required. Whether surgery or air enema is needed should be decided based on the actual color ultrasound results and a comprehensive diagnosis by the clinician.
