An anal fistula is a small tunnel that develops between the end of the intestine (anal canal) and the skin near the anus. It is a painful and uncomfortable condition that can be caused by a variety of factors, including infection, injury, or surgery.
Symptoms of an anal fistula can include pain, swelling, and discharge near the anus. The pain may be worse when sitting, and there may be a constant feeling of pressure or discomfort. Some people may also experience fever, constipation, and difficulty controlling bowel movements.
Anal fistulas are typically diagnosed by a physical examination and imaging tests such as an MRI or CT scan. These tests can help to determine the location, size, and shape of the fistula, as well as the presence of any abscesses or other complications.
Treatment for anal fistulas typically involves surgery. The goal of surgery is to drain the abscess and close the fistula tract. There are several surgical techniques that can be used, including fistulotomy (opening the fistula and allowing it to heal from the inside out), seton placement (placing a thread through the fistula to keep it open and allow it to heal), and fibrin glue injection (injecting a substance into the fistula to promote healing).
Recovery from anal fistula surgery can take several weeks. During this time, it is important to keep the area clean and dry, and to avoid strenuous activity. Pain and discomfort can be managed with over-the-counter pain medications and sitz baths.
Prevention of anal fistulas is not always possible, but certain measures can be taken to reduce the risk. These include maintaining good hygiene, avoiding constipation, and treating any underlying conditions such as Crohn’s disease or inflammatory bowel disease.

It is a painful and uncomfortable condition that can be caused by a variety of factors, including infection, injury, or surgery. Symptoms include pain, swelling, and discharge near the anus.
