Recently, the clinic saw a lot of small children, pimples around the anus, red, swollen and pus, the child cried, the family is very worried and anxious, I briefly talk about from the professional: this kind of situation, more to consider is a pediatric perianal abscess, or infantile anal fistula. This kind of disease has several characteristics: 1, the highest incidence in the first three months of life; 2, the onset of diarrhea or perianal hygiene is not good; 3, boys are more common, female infants less; 4, there is a certain degree of self-healing may be. Neonates are the weakest period of intestinal immune function, early rectal mucosal secretory IgA is absent or reduced, resulting in intestinal local immune deficiency. Normal children after birth gradually mucosal villi formation, after 1 year of age can be established to complete the infection defense mechanism, immunity enhancement, the onset of disease also gradually reduced. So this kind of disease should generally by non-surgical treatment plan, such as disinfection, anti-inflammatory, external drug such as our hospital even gardenia alum solution, etc., invalid recurrent episodes of surgical treatment. Parents calmly deal with to do in mind, then need to go to the hospital, let professional doctors or specialists for its diagnosis and treatment, some infections pus need to drain pus in time. A part of the baby after draining pus, along with the immunity improvement, has the self healing possibility!
