Compared to anal fistula and hemorrhoids, anal fistula should be a little more serious. First of all, there are many types of hemorrhoids, some symptomatic and some asymptomatic. If there are no symptoms of hemorrhoids will not need to be treated, relatively light, and only symptomatic hemorrhoids need to be treated, most of which can be treated conservatively. That is, a light diet, avoiding spicy, stimulating foods, avoiding alcohol, and practicing good hygiene habits can generally be relieved and can prevent hemorrhoids from happening again. If the hemorrhoid worsens, that is, if the swelling around the anus protrudes very significantly, with pain, difficulty in returning or bleeding, surgical removal is needed. Unless the condition is very serious and the patient is bleeding so heavily that it may cause life-threatening effects. Secondly, anal fistula is mainly after the inflammation of the perianal area, generally self-healing fistula is formed, there is an internal mouth inside the anus and an external mouth on the skin around the anus, belongs to the inflammatory infection disease. The actual fistula will require surgery once the diagnosis is clear, if not, it may progress into a complex anal fistula, which is quite troublesome to treat.
