[Intussusception in the newborn (author's transl)]

A five day old male neonate had bloody stools and decreasing appetite. He was subjected to laparotomy after x-ray investigations had shown an intussusception. This was due to a cystic duplication of the ileum just before the ileocecal valve. After an ileocecal resection the postoperative course was uneventful. Special problems of the intussusception in the newborn are discussed.
