The need for surgery is mainly the following cases: First, hemorrhoids: divided into internal hemorrhoids, external hemorrhoids, mixed hemorrhoids internal hemorrhoids: mainly with blood in the stool, bleeding bright red, bleeding during defecation, was a drip drip drip type jet bleeding, if this state bleeding frequently, several times a month, you need to perform surgery, mainly on the bleeding hemorrhoid nucleus for ligation bleeding. Secondly, there is often a swelling out of the stool, some self-return, some need to use the hand to return to the anus, this situation, repeated episodes, or frequent episodes, but also need to perform surgery, the line of ligation excision, if not surgical, a hemorrhoidal nucleus repeated friction, prone to breakage, infection, bleeding, and the second is the hemorrhoidal nucleus is easy to increase the size of the hemorrhoidal nucleus, prone to Dun, once the Dun, the pain is extremely intense. Of course, if the internal hemorrhoids are not often bleeding, and the amount of bleeding is small, a few drops or stained paper, and not often out, or no symptoms at all, such a situation, do not need surgery, can be used externally with some ointment or hemorrhoidal suppositories, will be able to play a very good therapeutic effect. Usually pay attention to regulate the diet, eat less spicy food, drink less alcohol and so on. You can do more anal lifting exercise can play a health care role. External hemorrhoids: some people can see or touch the anus some skin, soft, some slightly painful, this is external hemorrhoids. Usually there is no uncomfortable feeling. Can not be surgery, usually pay attention to cleanliness and hygiene can be. But if this kind of skin, often pain, itching, or hard texture, that is the complication of infection, this situation, you need surgery, surgical resection can be. Mixed hemorrhoids: there are symptoms of both internal hemorrhoids and external hemorrhoids. According to what I just said, bleeding, pain, prolapse often occur, need surgery, if the symptoms are light, infrequent attacks, can be conservative treatment. One more special kind of external hemorrhoid is mentioned: it is thrombosed external hemorrhoid. Thrombosed external hemorrhoids: is the anal edge of the visible purple dark mass, it is the anal subcutaneous blood vessel rupture, blood coagulation in the subcutaneous caused. Most of them occur in 1-2 days after straining to defecate, and the pain is heavy. In this case, if the lump is small, such as the size of soybean grains or peanut size, can be temporarily conservative treatment, external medication fumigation, the lump can gradually shrink, absorption, no harm to the human body. But when the lump (that is, thrombosed hemorrhoid nucleus) larger, or more, the pain is heavier, this time the need for surgical treatment, incision of the skin, peeling off the thrombus, the operation is simple, fast recovery. Here again, we remind you that is hemorrhoids, whether internal, external, mixed hemorrhoids, will never be cancerous. Hemorrhoids are enlargement or hypertrophy or downward movement of normal tissues in the body. It will not be cancerous, please do not panic about hemorrhoids. Secondly, anal fissure is divided into acute anal fissure and chronic anal fissure, acute anal fissure is a sudden anal canal skin damage, pain out of the situation, short history, generally no more than six months. For acute anal fissure, no matter children or adults, can be conservative treatment. Chronic anal fissure, more than half a year of the course of repeated episodes, more combined with complications, such as fissure of the lower end of the sentinel hemorrhoids, fissure of the upper end of the anal papilloma, there are also subcutaneous fistulae, the patient’s pain is heavy, or even anal stenosis, defecation pain, defecation difficulties, fear of defecation, this situation must be operated on, and only the operation can solve the problem of pain, the surgical excision of fissure, hemorrhoids, anal papillomas, subcutaneous fistulas, and to the anal sphincter, and the operation is not only the pain, but also the pain. And the anal sphincter for release. Third, perianal abscess occurs around the anus, the edge of the purulent mass, it is formed by the anal gland infection in the anus, the infection site of the inner mouth is the key to the disease, the mass gradually increased, the edge is not very clear, there is pain, anal swelling feeling. Patients with deep abscesses also have fever. The occurrence of perianal abscess, should be early surgery, the abscess incision drainage. If not operated, the abscess is easy to develop along the perianal space, the scope of expansion. Even if this is not surgery, conservative treatment and healing, will still recur many times in the future. Fourth, anal fistula anal fistula is perianal abscess self-broken or surgical incision and drainage and the formation of, it has an internal mouth, external mouth and fistula. Anal fistula and perianal abscess are two stages of the same disease. Before it breaks down, it is called an abscess, and after it breaks down, it is called an anal fistula. An anal fistula must also be operated on. Anal fistulas can partially heal on their own. In adults, fistulas are very unlikely to heal on their own, so they should be treated surgically. The way of surgery according to the fistula and the internal and external mouth situation. Fifth, anal papilloma Anal papilloma is actually uncommon, most patients for anal papillary hyperplasia, smaller, can be observed. For larger anal papilloma, hard, white color, smooth, although the cancer rate is low, but also should be removed. Sixth, rectal polyps for rectal polyps need to perform surgery. Small polyps can be detected through anoscopy or colonoscopy; large polyps with tips can be detached from the anus and should be removed as soon as possible to prevent cancer.
