Hemorrhoids are vascular diseases commonly seen in the anus and intestines and inherent in humans, and so far there has been no retrieval that animals naturally get hemorrhoids. Clinically, it is mainly characterized by bleeding during bowel movements, something coming out, pain and itching. Why should hemorrhoids not be underestimated? Take bleeding during bowel movement as an example, some bleed less, some bleed more, some bleed in drips, some bleed in jets. It is not uncommon to see patients who bleed during bowel movements, become dizzy, nauseous, or even pass out in the toilet. This is iron deficiency anemia caused by bleeding hemorrhoids. Many of our hospitalized patients have this condition. For example, one of the patients in Weishan, who had surgery with me, was only 19 years old, and had fainted and died 2 times before surgery due to hemorrhoidal bleeding (hemorrhagic shock), and the iron deficiency anemia took more than 3 months to make up for it. More annoying, there are a lot of patients bleeding in the stool, according to hemorrhoid treatment for 3 months, some 2 years, the result of the outpatient clinic was actually rectal cancer, lost the best time for treatment, because rectal cancer bleeding and hemorrhoid bleeding has similarities, inexperienced doctors can not see. If rectal cancer is detected in early stage within 1cm, there is a big difference between early detection and mid-late stage detection. Early detection hardly affects the life expectancy and costs very little money (4-7,000 yuan), while mid-late stage not only affects the life expectancy, but also brings a heavy economic burden to the family and the society, which is as little as a few tens of thousands of yuan, or as much as hundreds of thousands of yuan. Therefore, the appeal: with hemorrhoid bleeding should be timely consultation, outpatient clinic in the rectum in the lower end of the rectum cancer finger diagnosis accuracy rate of more than 90%, and 80% of the intestinal tract, most of the cancers in the rectum in the lower part of the length! And then take something out, out of something is mostly hemorrhoids, a few also have anal papilloma, rectal polyps, anorectal cancer. Most of the pain is hemorrhoids prolapse can not reply or local inflammation, thrombosis, anal fissure, perianal abscess, anal cryptitis, anal canal rectal inflammation, etc., a few also have anal canal cancer appeared pain. The most common itching is anal eczema, anal fistula, hemorrhoids and so on. So the appearance of hemorrhoid symptoms should not be underestimated, timely consultation, save time and money.
