Children with intussusception are usually cured. Early diagnosis and proper treatment are the keys to recovery. Generally, children with intussusception can be cured through non-surgical treatment. In severe cases, surgery is needed. In daily life, intussusception in children is a common phenomenon, which is better to be treated. If the intussusception is mild, through timely treatment and handling, it can avoid bringing serious harm to the child, and the treatment is relatively simple, and conservative non-surgical treatment can be taken, such as through air enema, barium enema and ultrasound under the water pressure enema treatment, so that the intussusception can be successfully reset. If a child’s intussusception is more serious and cannot be treated conservatively, open surgery is needed. Although it is a major surgery, the surgical technique is now more mature. If there is no intestinal necrosis, the intussusception can be repositioned by squeezing; if there is intestinal necrosis or the intussusception cannot be repositioned, the corresponding intestinal segment needs to be surgically removed. Infants and young children under two years old are prone to intussusception. If a healthy and active child suddenly develops unexplained paroxysmal crying, vomiting and abdominal mass, etc., we should consider the possibility of intussusception, and the parents should bring the child to the hospital in time to get a clear diagnosis as soon as possible.
