1. What is hemorrhoids?
People often say that "ten people have nine hemorrhoids". Although it is an exaggeration, it also shows that the incidence of hemorrhoids is high. What is hemorrhoids? Hemorrhoids evolved from the word "chi", which means that they are higher than bulge. We can call the soft masses that bulge inside and outside the anus as hemorrhoids, and their essence is a venous mass formed by the tortuous expansion of veins. Through extensive pathological observations, Professor An Ayue, the inventor of An's therapy, confirmed that highly tortuous and dilated veins, tissue edema, inflammatory cell infiltration, and intravascular thrombosis can be seen in the hemorrhoid tissue. Hemorrhoids are divided into internal hemorrhoids, external hemorrhoids, and mixed hemorrhoids by the dentate line (the dividing line between the skin of the anal canal and the rectal mucosa, about 3-4 cm from the anal margin). The hemorrhoids above the dentate line are called internal hemorrhoids, and the dentate line is called external hemorrhoids below. , Hemorrhoids straddling the dentate line up and down are called mixed hemorrhoids.
Hemorrhoids is a disease unique to humans. It is the price that humans pay for walking upright and freeing their hands. After the human body is in an upright state, the anus is located at the lowest end of the digestive tract, and the resistance to venous return is the greatest. In addition, the venous return needs to pass through the abundant perianal muscle tissue and anal veins. Without a venous valve to prevent venous return, local blood return from the anus and rectum is becoming more and more difficult. It can be described as "a long way to go". This is the internal cause of hemorrhoids in humans; long-term constipation, long-term squatting, long-term weight-bearing squeezes local blood vessels in the anus , Aggravate the venous reflux disorder, the anorectal congestion and edema caused by overeating and spicy food can also lead to the occurrence of hemorrhoids, these are the external causes of hemorrhoids.
2. What are the symptoms of hemorrhoids? What diseases need to be differentiated from?
The symptoms of hemorrhoids include: blood in the stool, prolapse of the mass in the anus, moist and itching anus, etc., such as hemorrhoid edema and thrombosis can be accompanied by severe pain, the above symptoms can occur alone or at the same time. Hemorrhoids blood in the stool is usually fresh blood, dripping, if the blood volume is large, it can be spray-like. The hemorrhoids can retract into the anus by themselves at the early stage of prolapse, and can only be returned into the anus with a hand support when it gets worse. Into the anus, called incarcerated hemorrhoids, can lead to hemorrhoid edema, thrombosis, necrosis of hemorrhoids and severe pain, which must be operated in time; moist and itching anus is caused by secretion stimulation after hemorrhoids prolapse.
Diagnosis of hemorrhoids In addition to the clinical symptoms, digital examination and anoscopy in the anus are very important. The digital examination in the anus can find abnormal masses within 7cm of the anus, exclude low rectal cancer, and anoscopy can clearly see whether the hemorrhoids have erosions and bleeding. Anoscopy can not clearly see the bleeding point of hemorrhoids, it is necessary to do a colonoscopy to further clarify the bleeding location, so as to avoid missed diagnosis of colon cancer, ulcerative colitis, colon polyps and other diseases.
