A portion of the intestine and its mesentery invaginates into the adjacent intestinal lumen. It can be classified into primary and secondary intussusception, with the former commonly occurring in infants under 2 years of age. Secondary intussusception is induced by organic lesions of the intestinal wall or lumen and is more common in adults. Based on the site of intussusception, it is further divided into: ileocolic type, small intestine type, and colonic type.

1. Regular paroxysmal abdominal pain, accompanied by symptoms of intestinal obstruction such as abdominal distension and fullness, vomiting.

2. Bloody stool, mostly resembling red jam. Bloody stool is found on the glove during digital rectal examination.

3. A sausage-shaped mass can be palpated in the abdomen, which is movable and tender. In ileocolic intussusception, a sense of emptiness can be felt during palpation in the right lower abdomen.

4. X-ray examination reveals intestinal distension and air-fluid levels. Barium enema in ileocolic or colonic intussusception often shows typical cup-shaped shadows or clamp-like filling defects.

1. Non-surgical therapy

is suitable for early infant intussusception, using barium or air enema reduction. The early reduction rate is relatively high.

2. Surgical therapy

(1) Simple reduction: Early manual reduction can be successful, that is, the hand is placed at the distal end of the intussusception, and the intussuscepted part is squeezed out in reverse. Avoid pulling the intussuscepted part out of the sheath to prevent intestinal rupture. When reduction is difficult, a slight pulling force can be applied to the intussuscepted part. After complete reduction, the blood supply of the intestinal wall should be observed. If there is no necrosis of the intestinal wall, no further treatment is needed.
