Many parents of affected children are very concerned about the problem, thinking that the baby is only so old, some just born may only be more than 10 days, some only 2-3 months, why long perianal abscess, is not congenital, some people tend to ask these questions. In fact, the causes of the formation of pediatric, infants and young children feel related to the following aspects: 1. The level of androgens in the body of infants and young children may sometimes appear to be transiently increased, and this hormone is mainly brought from the mother. Excessive hormones can lead to well-developed glands around the anus and a strong secretion, while the anal glands can cause local infections once they are blocked for some reason during the secretion process. Male babies, on the other hand, can also produce androgens because of their testicles, making anal gland secretion more vigorous than in female babies. This is why sometimes in clinical practice, the majority of children with perianal abscesses are boys, and the majority of them are boys, and the girls have less; 2. There is also a part related to the anatomical structure of children, the bending of the sacrum has not yet formed, and the rectum and anal canal are close to a straight line, plus the tension of the internal sphincter of the anus is relatively weak, so feces can easily press directly and damage the mucous membrane of the anus, which leads to friction resulting in damage, and cause bacterial infection and cause perianal abscess; 3. Girls form rectal flexion, which changes the direction of fecal pressure, so girls often do not appear clinically as many perianal abscesses as male babies; 4. Infants and children still have more stools, so they become contaminated with feces and pollute the anal sinus tissue and anal gland tissue, which also easily cause perianal abscesses; 5. The local immune structure of children has not yet developed The immunoglobulin ratio of the perfect rectal mucosa is reduced, so if you do not pay attention to local hygiene and low resistance, it can also lead to perianal abscesses. These aspects of the causes are the most important aspects of the causes of perianal abscess in babies.
