Which district of Shanghai has a good anorectal hospital?

Anorectal experts in Anal Thai Hospital said that external hemorrhoid is a kind of hemorrhoid, and it is a soft vein group that grows under the annular dentate line. Its symptoms are mainly pain, lump, itching, secretion and so on. According to the different pathogenesis of external hemorrhoids, the types of external hemorrhoids are also different. Clinically, it is often divided into connective tissue external hemorrhoids, varicose external hemorrhoids, inflammatory external hemorrhoids and thrombotic external hemorrhoids. 1, external hemorrhoid: the flap on the edge of anus grows gradually, with soft texture, generally painless and bleeding. Only when the anus has foreign body sensation, occasionally swelling and congestion will cause pain. Once the swelling disappears, the flap still exists. 2, venous external hemorrhoids: mostly due to repeated prolapse of internal hemorrhoids in the middle and late stage, or due to increased abdominal pressure during pregnancy. , so that the superficial vein and subcutaneous lymphatic reflux is blocked, causing the external venous plexus below the anal canal tooth line to expand and varicose. Its clinical manifestations: there are oval or long tumors in local areas, which are soft to the touch and usually not obvious. When defecation or squatting increases abdominal pressure, the tumor volume increases to dark purple, which is more difficult to press. After defecation or massage, the tumor volume can be reduced, smaller and softer. Generally, there is only a feeling of bloating, and there is no pain. If the tumor does not shrink after defecation, it will cause pain when it causes edema of surrounding tissues. Patients with varicose external hemorrhoids are often accompanied by internal hemorrhoids. 3, thrombotic external hemorrhoids: due to constipation, excessive force during defecation, or after strenuous exercise, the external veins of hemorrhoids rupture and quickly form blood clots. Its clinical manifestations: sudden and severe pain in the anus, and a tumor, which is very sensitive, will cause pain at the slightest touch, so defecation, sitting, walking and even coughing will aggravate the pain.
