Anal fistulas are difficult to heal on their own without surgical treatment, and even if they heal on their own in a short period of time, recurrence can occur. This is because the fistula is mainly rectal through the perianal area, there is a channel to the perianal skin, which is an abnormal channel, and there will be fecal secretions and feces through the sinus outflow, resulting in constant and repeated infections, especially when on fire, tired, and spicy stimulating diet, and a lot of alcohol consumption is easy to relapse. The actual surgery is recommended to be done in a timely manner, and it is recommended to go to a regular specialist hospital for systematic examination. The most important thing is that you can get a good idea of what you want to do. If it is a low anal fistula, it can be done by local sinus excision.
