Little Dot is 2 years old and looks lively and cute. When he was half a year old, his parents found an abscess next to his anus and went to the hospital for an examination, the doctor said he had to be hospitalized for surgery. The doctor found that the fistula had developed into 3 fistulas, and to treat it completely, all 3 fistulas had to be cut open at the same time, which made the trauma very large and painful for the child. Perianal abscesses are more common in children, especially in newborns or infants. This is because children have delicate skin, low immune function, poor resistance, and relatively strong secretion of sebaceous glands, plus children are prone to dermatitis from using diapers, resulting in infection of hair follicles, sweat glands, and sebaceous glands and formation of pus amidships. However, perianal abscesses in infants and children are generally subcutaneous infections, which can be treated conservatively or surgically depending on the situation, and even surgical treatment is less traumatic, less painful and quicker to recover. If not treated in time or improperly treated, the disease can be prolonged and then cause complex anal fistula or rectal fistula, causing more pain to the affected children.
