The cause of fistulas in children is relatively rare, but infants within the first 3 months of life and children under 1 year of age often develop painful, septic anal fistulas, which are called infantile fistulas because they have different etiology and clinical features from those of adults. The first thing you need to do is to get a good idea of what you’re doing. The symptoms can be alleviated quickly after the drainage of pus, and most of them can heal on their own, and some of them heal on their own as they grow older. Once an infant fistula occurs, symptomatic treatment should be carried out in a timely manner, such as daily cleaning of the anus and sitz bath, use of soft diapers, and appropriate use of antibiotics and topical anti-inflammatory creams to control and reduce the occurrence and development of abscesses to accelerate self-healing. For children with recurrent episodes that cannot heal on their own, surgery should be performed at a later date until they can afford surgery, and the age of surgery should be 5 to 10 years old.
