Intussusception is a common surgical disease in infants and young children, characterized clinically by crying, abdominal pain, abdominal distention, the passage of jelly-like stools, and vomiting. Auxiliary examinations for this condition primarily involve abdominal ultrasonography, though occasionally an abdominal X-ray can be performed. If a child experiences intussusception, treatment can vary depending on the severity; mild cases might be treated with an air enema. However, if the symptoms of intussusception are severe and prolonged, leading to ischemic necrosis of the intestines, surgical intervention is definitely required. In summary, the examination for intussusception primarily involves abdominal ultrasonography.
