As the saying goes, "ten men and nine hemorrhoids", don't forget to prevent "hemorrhoids" in a healthy life. I once accepted a media interview and gave a special answer on hemorrhoids knowledge. Now I provide it to friends to share and provide valuable opinions.
Q: What is hemorrhoids?
Answer: In the lower end of the rectum and anal canal of human beings, there are blood vessels and supporting tissues within one week of the submucosa or subepithelium, which are called "vascular cushions", and the blood vessels inside are called "hemorrhoid blood vessels", vascular cushions It is innate and has important functions. First, the vascular cushion assists the anus to control defecation through pressure changes; secondly, because the vascular cushion is elastic, it can protect the muscles around the anus and is not easily damaged by dry stool; at the same time, the vascular cushion is relatively soft, which can ensure the perfect closure of the anus. Keep the area around the anus clean. When the supporting tissues relax and the blood vessels of the hemorrhoids become abnormally varicose and prolapse, some people develop hemorrhoids.
Q: How many types of hemorrhoids are there? What are the symptoms?
Answer: There are three types of hemorrhoids: internal, external, and mixed. If hemorrhoids occur above the dentate line of the anus, they are called internal hemorrhoids, and underneath are external hemorrhoids. Symptoms vary depending on the location. The typical symptoms of internal hemorrhoids are bleeding, prolapse and itching around the anus because of the thin mucous membrane, but they are generally not painful because they are innervated by the autonomic nerves. External hemorrhoids are prone to cause anal canal insufficiency and secretions to irritate the anus, so the typical symptoms are itching, burning, dirty around the anus, and easy compression, venous blood flow stasis, leading to thrombosis, so the pain symptoms are more serious.
Question: Can hemorrhoids be diagnosed with symptoms of blood in the stool?
Discomfort around the anus, something growing in the anus, bleeding from the anus, pain around the anus, etc., may not necessarily be hemorrhoids. There are many diseases that also have such manifestations, such as abscesses, tumors, condyloma and warts around the anus. Anal fissures, etc., need to be diagnosed after a doctor's examination, including visual examination, digital examination, and anoscopy.
Q: Who are the high-risk groups of hemorrhoids?
Answer: Everyone has vascular pads, but not everyone has hemorrhoids. First, people with long-term high abdominal pressure, such as those with constipation; and long-term standing workers, such as teachers and salespersons; and people who sit hard for a long time, such as drivers, etc. These people are likely to cause increased hemorrhoidal blood pressure. Hemorrhoids are formed. As the saying goes, "ten people have nine hemorrhoids", but in fact, the incidence of symptomatic hemorrhoids is not so high. The incidence rate in the United States is 4.4%, and that in China is about 6.4%.
Q: To what extent does hemorrhoids need treatment? What are the treatment methods?
Answer: Hemorrhoids are divided into four degrees, from light to severe, degree 1: blood in the stool, hemorrhoids do not shed, and bleeding stops after stool; degree 2: blood in the stool, with internal hemorrhoids prolapse, and self-recovery after stool; degree 3: reduction of blood in the stool , Tired or increased intra-abdominal pressure, internal hemorrhoids prolapse, need to be repaid by hand; 4 degrees: internal hemorrhoids prolapsed cannot be repaid. Severe prolapse does not mean that the condition is serious, because individual differences, the length of the anal canal varies, which will affect the degree of prolapse. The need for treatment depends on the symptoms. Generally speaking, patients with degree 1, 2, and a small number of degree 3 hemorrhoids can be treated conservatively, for example, changing lifestyles, eating habits to relieve the condition, local injection of sclerosing agent, freezing, banding and anal expansion treatment, etc. Some patients with degree 3 and 4, as well as patients whose conservative treatment is not effective, should be treated with surgery. The LigaSure hemorrhoidectomy that we have adopted in recent years has been satisfied with the majority of patients due to its minimal invasiveness, light postoperative pain and fewer complications.
