There are always people, go to the bathroom as if it was torture, not only time-consuming, but also sitting on the toilet grimace, a get up, the toilet bowl a blinding red, what is wrong with them? Don’t ask, ask is hemorrhoids! Clinical hemorrhoids are divided into internal hemorrhoids, external hemorrhoids, mixed hemorrhoids three kinds of hemorrhoids, of which internal hemorrhoids and specific subdivisions, together with the understanding of understanding to see which kind you are? 1, hemorrhoids types are slightly different, the right number to understand which one you are? Hemorrhoids are the most common anorectal disease, hemorrhoids in infants and young children are rare, but with age, the incidence gradually increased. And hemorrhoids have a long course, as little as 0.5-2 years, more years or decades. Hemorrhoids are usually bounded by the dentate line and can be divided into three types: internal hemorrhoids, external hemorrhoids, and mixed hemorrhoids. Internal hemorrhoids, external hemorrhoids schematic which in the dentate line above the internal hemorrhoids, the surface covered with mucous membrane, stool, hemorrhoidal mass out of the anus, severe ring-shaped out or need to use the hand back, sometimes accompanied by anal fall, swelling, foreign body sensation, when there is incarceration can be pain, etc., and sometimes the mucous membrane erosion. Below the dentate line is called external hemorrhoids, the surface is covered with skin, hemorrhoids are born outside the anus, the color is purple and dark, usually does not bleed, but there is discomfort or pain. According to its clinical symptoms and lesions of different traits of tissue structure can be divided into connective tissue external hemorrhoids, varicose external hemorrhoids, thrombosed external hemorrhoids and inflammatory external hemorrhoids. In the vicinity of the dentate line, internal and external hemorrhoids exist at the same time and are linked together, known as mixed hemorrhoids, for the skin and mucous membrane junction tissue cover. Internal hemorrhoids are formed when the supporting structures of the anal cushion, the venous plexus and the anastomotic branches of the arteries and veins undergo pathologic changes, resulting in congestion, hyperplasia and hypertrophy of the anal cushion. External hemorrhoids are formed by pathological dilatation of subcutaneous venous plexus or connective tissue hyperplasia on the distal side of the dentate line. Internal hemorrhoids through the rich venous plexus anastomosis branch and the corresponding parts of the external hemorrhoids interconnected fusion formation of mixed hemorrhoids. 2, the progress of internal hemorrhoids divided into four degrees, each degree of symptoms are different internal hemorrhoids according to the degree of prolapse can be divided into 4 degrees, Ⅲ degree of internal hemorrhoids more than the formation of mixed hemorrhoids, the performance of internal hemorrhoids and external hemorrhoids at the same time, there can be pain and discomfort, itching, which itching is often due to hemorrhoids prolapse when there is a mucous secretion outflow caused by. If the internal hemorrhoid is severe, it may also manifest as jet-like bleeding. Hemorrhoids grading chart Ⅰ degree: blood during defecation, dripping blood or blood on the handkerchief, bleeding can stop by itself after defecation, hemorrhoids do not prolapse out of the anus. Anoscopy shows that the anal cushion is congested and swollen, the mucosal surface is mildly eroded, there may be local bleeding spots or bleeding tendency, the hemorrhoids are angiomatous, and the hemorrhoids are about 1cm. The anal cushion is swollen and soft on palpation. II degree: there is often blood in the stool, prolapse from the anus during defecation, and automatic return after defecation. Anoscopy shows that the anal cushion is swollen, the mucous membrane is rough and dark or vesicose, its surface is localized or there are bleeding spots or bleeding tendency, the hemorrhoidal nucleus is venereal aneurysm with fibrosis, and the hemorrhoidal nucleus is larger than 1cm. the hypertrophied anal cushion can be detected on palpation, and the texture is soft. Ⅲ degree: defecation or standing for a long time, coughing, exertion, weight-bearing hemorrhoids out of the anus, need to use the hand to assist the return, may be accompanied by bleeding. Anoscopy shows that the anal cushion is swollen, the bulge is significant, the hemorrhoid nucleus is larger, and the boundary still exists. The mucosal surface is fibrotic with varicose veins, the groove between the anal cushions is shallow, and the hemorrhoids are fibrotic with varicose veins. Palpation can be found in the anal cushion of hypertrophic bulging mass, soft, there may be local hard nodules. Degree Ⅳ: hemorrhoids in the anus for a long time outside, can not return or return after prolapse, can be accompanied by bleeding, internal hemorrhoids can be accompanied by strangulation, incarceration. Anoscopic examination of the mucous membrane color purple dark, the surface is often erosion, accompanied by thrombus, may have bloody mucus cover, the anal cushion between the groove disappeared, the internal hemorrhoid was ring, for the venous aneurysm type accompanied by thrombus. Palpation of the anus is generally loose, often can be found thrombus small hard nodules. References [1] Chen Xiaoping, Wang Jianping, Zhao Jizong, eds. Surgery (9th ed.).
