Hemorrhoids, also known as hemorrhoids, including internal, external and mixed hemorrhoids, are a chronic disease in which varicose veins occur at the base of the anorectum and in the venous plexus of the anal mucosa, resulting in the formation of one or more soft venous masses. The common symptoms of internal hemorrhoids and mixed hemorrhoids are bright red, painless blood in the stool and prolapse of foreign bodies from the anus. It is divided into 4 degrees according to the severity of clinical symptoms: degree I: blood in the stool, dripping blood, bleeding can stop on its own after the stool; no hemorrhoid prolapse. Degree II: Hemorrhoid prolapses during defecation and can be returned by itself after defecation; there is often blood in the stool. Degree III: Hemorrhoids prolapse during defecation or prolonged standing, coughing, exertion, or weight-bearing, and need to be returned by hand; blood in the stool may or may not be present. Grade Ⅳ: Hemorrhoids continue to prolapse and cannot be retracted, or even have embedded edema; blood in the stool is less common. (2) External hemorrhoids usually have no special symptoms, but there may be swelling and pain when thrombosis and inflammation occur. Treatment: I and II degree internal hemorrhoids and mixed hemorrhoids are mainly treated conservatively, including external hemorrhoid cream, hemorrhoid suppositories such as anal tide ointment, Ma Yinglong hemorrhoid cream, taining suppositories, etc. Oral medications to improve venous lymphatic insufficiency such as Diosmin tablets, Mai Zhi Ling, etc. The most commonly used clinical procedures are traditional hemorrhoid ligation and minimally invasive PPH technique. The latter has the advantages of less trauma, less bleeding, less postoperative pain, fewer complications and faster recovery than the former; however, the price is more expensive than the traditional procedure. As for the treatment of external hemorrhoids, generally asymptomatic external hemorrhoids do not require treatment; those with pain and itching can consider topical hemorrhoid cream treatment, and surgical removal can be considered after treatment is ineffective.
