The healed skin of anal fistula can be promoted to heal by regular sterilization and protection of the broken skin area, and if the symptoms get progressively worse, another operation may be needed. The broken skin may be caused by the patient’s improper care after the operation, such as the local area is not kept dry, often friction and so on. You can use iodine povidone to disinfect the skin regularly, keep the area dry and hygienic, avoid sitting for a long time, and change the underwear frequently to promote the healing of the broken skin area. If the anal fistula patients have leftover fistula during the operation, it may also appear broken skin after the operation. When the fistula recurs, there may also be broken skin, usually with mucous secretions oozing out. In both cases, another surgical removal is recommended to avoid gradual worsening of the symptoms and disruption of daily life. It is recommended that patients seek timely medical attention and standardized treatment under the guidance of a doctor.
