Simply put, hemorrhoids are masses formed by varicose vein clusters; asymptomatic hemorrhoids don’t require treatment, and symptomatic hemorrhoids do. Specifically, different types of hemorrhoids form differently. Hemorrhoids are the most common anal and intestinal disease, there are internal, external and mixed hemorrhoids. Different hemorrhoid formation and clinical manifestations, etc. differ. Internal hemorrhoids are formed by a varicose mass of venous plexus on the rectum above the dentate line. Internal hemorrhoids occur in the truncated position 3, 7, 11 o’clock position, mainly manifested as intermittent blood after stool, hemorrhoids prolapse, in the absence of thrombosis, incarceration and infection when the internal hemorrhoids is no pain. External hemorrhoids are formed by the varicose mass of veins under the rectum below the dentate line. External hemorrhoids are mainly characterized by anal discomfort, dampness and uncleanliness, which may be accompanied by itching. When there is thrombosis, it can be accompanied by severe pain in the anus, which is called thrombosed external hemorrhoids. Mixed hemorrhoids are formed by the internal hemorrhoids through the rich venous plexus anastomosis branch and the corresponding parts of the external hemorrhoids fused with each other. Mixed hemorrhoids can have both internal and external hemorrhoid manifestations. For the treatment of hemorrhoids, in principle, asymptomatic hemorrhoids generally do not need to be treated, and symptomatic hemorrhoids focus on alleviating or eliminating the symptoms rather than eradicating them. For thrombosed external hemorrhoids, the thrombosed external hemorrhoid stripping operation should be carried out in time. Different types of hemorrhoids formation, blood supply, venous return, lymphatic drainage, as well as treatment modalities are very different, such as patients with hemorrhoids symptoms manifested serious, prolapse or pain discomfort, it is recommended to consult the anorectal department in a timely manner, under the advice of a professional doctor, to take appropriate treatment measures.
