The soft venous masses formed by dilated and tortuous venous plexuses under the mucous membrane at the end of the human rectum and under the skin of the anal canal are called hemorrhoids, also known as hemorrhoids, hemorrhoids, hemorrhoids disease, hemorrhoids disease, etc. Hemorrhoids include internal hemorrhoids, external hemorrhoids, and mixed hemorrhoids, and are a chronic disease in which one or more soft venous masses form as a result of varicose veins at the base of the anorectum and the anal mucosa. The common symptoms of hemorrhoids 1, fecal bleeding: painless, intermittent bright red blood after the stool is its characteristic, and is also a common symptom of internal or mixed hemorrhoids early. The bleeding usually occurs before or after a bowel movement, either pure blood in the stool or mixed with stool. The blood is bright red, and its bleeding is in the form of spraying, dripping, or wiping with blood, etc. 2. Prolapse: The swelling inside the anus appears to prolapse, which is mainly a symptom of middle and late stage internal hemorrhoids. As the nucleus of the internal hemorrhoid keeps increasing, the mucosa and submucosa are separated from the anal layer, and when defecating, the nodule of the internal hemorrhoid can descend below the dentate line, free from the anal canal and prolapse through the anus. The lighter ones will only come out of the anus when defecating, while the heavier ones can come out when coughing, pressing the abdomen or squatting hard. 3, painful stool: bleeding perianal pain phenomenon when stool. Because the perianal nervous system is more developed and sensitive, it is easy to stimulate the pain. Generally manifested as mild pain, stabbing pain, burning pain, swelling pain, etc. 4, rectal cramps: anorectal cramps are mainly the symptoms of internal hemorrhoids. If the internal hemorrhoid is infected, embedded, or has strangulated necrosis, this will lead to severe cramping pain. In mild cases, there is a feeling of swelling and falling, and in heavy cases, there is heavy falling pain. 5.Anal itching: Itching symptoms appear in the anus and perianal skin. Mainly due to anal secretions, prolapsed hemorrhoid nucleus and surrounding skin is stimulated, the skin is moist all day long, thus producing itching, resulting in anal eczema and itching. 6, secretions: anal outflow secretions, rectal mucosa long-term stimulation by hemorrhoids, causing increased secretions, late internal hemorrhoids, because of the anal sphincter muscle relaxation, often have secretions from the anus outflow. In the lighter cases, the secretion flows out when you have a bowel movement, and in the heavier cases, it flows out naturally even when you don’t have a bowel movement. The advantages of PPH minimally invasive surgery are 1. The operation time is short: the whole process only takes about half an hour. 2.Less painful surgery: the hemorrhoids that have prolapsed from the anus are pulled back into place, while the blood vessels that provide blood to the hemorrhoids are cut off, without damaging the perianal skin, so there is almost no pain after surgery. 3.Little surgical trauma and quick recovery: the anastomosis circumferential excision of mucosa is a non-open wound, less bleeding, eliminating the trouble of changing after surgery, and you can resume normal life soon. 4.Safety of surgery: no need to remove the anal cushion, the maximum degree of preservation of the normal function of the anus, to avoid anal stenosis, anal incontinence and other complications. 5.Surgery is suitable for many people: because of less damage, it is especially suitable for middle-aged and elderly people, white-collar people who pay attention to efficiency and those who relapse from traditional treatment, and patients with mild prolapse and internal prolapse of rectal mucosa.
