. Expert introduction: Anal fistula is a common anorectal disease, which is a perianal granulomatous catheter formed by the rupture of perianal abscess for a long time. Anal fistula mostly occurs in men aged 20-40. There is no cure for this disease and it must be treated. Which hospital should I go to for treatment? Experts from Xiangyang Fourth Hospital of Anal Fistula Hospital took us to look at the clinical symptoms of anal fistula: 1, pus: a small amount of purulent, bloody and mucinous secretions flowed from the external orifice of anal fistula, and pus accumulated in the fistula, causing local swelling and pain, and even fever. Large and high anal fistula, because the fistula is located outside the sphincter and is not controlled by the sphincter, feces and gas are often discharged. 1, Pain: The fistula is unobstructed and there is no inflammation, so I often feel no pain, only local swelling and discomfort, which is aggravated when walking. When fistula infection becomes inflamed, it will cause pain. You can also feel a burning sensation in the lower rectum and anus, and feel pain when defecating. 2, itching: Because pus constantly stimulates perianal skin, it often feels itchy, perianal dampness and discomfort, skin discoloration, epidermal shedding, and sometimes eczema. 3, poor defecation: complex anal fistula, if not treated in time, can affect the relaxation and closure of the anus, feel difficult when defecating, poor defecation. .
