Rectal prolapse is an anal prolapse disease in which the rectum and sigmoid colon are displaced downward and prolapse out of the anus. It is mostly seen in male children over 2 years of age and elderly people, and the incidence is higher in poor rural areas. The occurrence of childhood prolapsed rectum is closely related to the children’s own imperfect development, small sacral bending and too vertical rectum. In addition, low nutrition and hygiene, long-term diarrhea, cough and other factors can trigger the occurrence of this disease. The characteristics of rectal prolapse in children 1, prolapse symptoms are light (only rectal mucosa prolapse); 2, good anal sphincter function (no relaxation, this point is the opposite of senile rectal prolapse); 3, can be cured by injection treatment, the prognosis is good. Since the disease is related to the growth and development of children, the symptoms of prolapse can be reduced year by year with the growth of age, and the majority of children will have their symptoms completely disappeared by the age of 14-17, leaving no sequelae. Medical treatment mostly emphasizes conservative treatment, such as medication, acupuncture and injection therapy. It is important to note that the child should be accompanied by an adult during defecation, and that the intestinal tube should be returned to the anus in time after prolapse. To avoid the occurrence of intestinal tube entrapment, necrosis. Advise the child to defecate in a sitting position to reduce abdominal pressure, so as not to aggravate the prolapse. Strengthen physical exercise, enhance physical fitness, pay attention to dietary hygiene, anal cleansing with warm water after defecation, and actively eliminate triggering factors can effectively improve the symptoms of rectal prolapse in children with rectum and promote their early recovery.
