anal fistula的意思|示意

Anal fistulas，also known as fistulas-in-ano, are small, infected tunnels that form between the skin near the anus and the inside of the anus or rectum. These fistulas can cause severe pain, itching, and discomfort. They can also be a source of infection to other parts of the body.

Anal fistulas can develop without any noticeable symptoms. Symptoms usually begin when the fistula becomes infected or swollen. Pain, itching, and discharge around the anus area may occur. Bleeding and discomfort during and after bowel movements may become more frequent. The severity of these symptoms can range from mild to severe.

Treatment for an anal fistula may include drainage of the fistula, medications to reduce inflammation and infection, and surgery. The type of surgery used will depend on the size and location of the fistula. Traditional surgery involves making an incision in the skin around the anus and removing any infected tissue. Laparoscopic procedures can be used to reduce the size and complexity of the incision and make the procedure less painful.

No matter the treatment, it is important to address the underlying cause of the fistula. This can include better hygiene of the anus area, stool softeners, and treatments to reduce infection and inflammation.

Anal fistulas can be a source of discomfort and embarrassment. However, with proper treatment, most fistulas can be successfully treated. It is important to talk to your doctor if you are concerned about symptoms associated with anal fistulas.
