Pictures of male hemorrhoids: Three reasons why men get hemorrhoids 1. The physiological structure of the human body leads to hemorrhoids.
When people are standing or sitting, the anus and rectum are located below. Due to the influence of gravity, the upward reflux of veins is quite blocked, which easily leads to poor blood flow and congestion, laying a hidden danger for the frequent occurrence of hemorrhoids.
Second, working conditions can easily lead to high incidence of hemorrhoids.
Drivers, teachers and office workers are sedentary people, and the physiological structure of the human body causes obstacles to venous return. In addition, sitting for a long time can easily lead to varicose veins and form a venous mass, which is hemorrhoids.
Third, genetic factors.
Genetically, some men's vein walls are inherently fragile, and their resistance is reduced, so they can't bear the pressure in blood vessels, so they gradually expand and cause hemorrhoids.
Fourth, bad living habits lead to
For work reasons, excessive drinking, smoking and eating spicy food can stimulate anus and rectum, make hemorrhoid venous plexus congested, and affect venous blood return. In addition, old age, chronic diseases and anal sphincter weakness lead to a high incidence of hemorrhoids.
Classification of hemorrhoids Hemorrhoids are divided into internal hemorrhoids, external hemorrhoids and mixed hemorrhoids according to different parts.
There is a jagged visible line at the junction of anal canal skin and rectal mucosa, which is called anal canal dentate line. Above the dentate line is internal hemorrhoid, and the supporting structure of anal pad, venous plexus and arteriovenous anastomosis branch is diseased or displaced, covering the rectal mucosa. Due to the contraction of the internal sphincter, the anal pad is divided into three parts: the left side, the right front side and the right rear side with a Y-shaped groove, so internal hemorrhoids are common in the left side, the right front side and the right rear side. Below the dentate line are external hemorrhoids covering anal mucosa, which can be divided into connective tissue external hemorrhoids, varicose external hemorrhoids and thrombotic external hemorrhoids; Mixed hemorrhoids with internal hemorrhoids and external hemorrhoids are the fusion of internal hemorrhoids and corresponding external hemorrhoids through venous plexus, that is, the anastomosis of upper and lower venous plexus. When the mixed hemorrhoid emerges from the anus and is plum blossom-shaped, it is called circular hemorrhoid. If incarcerated by sphincter, incarcerated hemorrhoids will be formed.
Misdiagnosis of hemorrhoids and rectal cancer
Because hemorrhoids and rectal cancer have similar sites, when some symptoms of rectal cancer and anal cancer overlap or are atypical, their clinical diagnosis is often mixed, and misdiagnosis is not uncommon. It is not uncommon to diagnose anorectal symptoms as hemorrhoids, which delays the treatment of rectal cancer. Another misdiagnosis was rectal cancer with some anal bleeding symptoms, which was misdiagnosed as hemorrhoids. Especially when they coexist, the diagnosis and treatment of hemorrhoids can be satisfied after examination, but the comprehensive and correct diagnosis can not be obtained for a long time. If the patient with the initial impression of hemorrhoids is carefully asked about the medical history and carefully examined, many mistakes in diagnosis can be avoided.
1. Hemorrhoids can occur in people of any age, and patients with rectal cancer are mostly middle-aged and elderly people.
2. Hemorrhoids patients have hematochezia because they grazed the affected area during defecation. Most of the blood drips down after it is discharged from the stool, so it is not mixed with the stool and there is no mucus. The stool of rectal cancer patients is often mixed with blood, mucus and thick liquid, and the stool habits will change obviously. The frequency of defecation increased, accompanied by urgency and heaviness. If diarrhea can't be relieved after taking the medicine, you should pay special attention.
It is the most effective method to put your finger into anus for examination. Because most hemorrhoids and rectal cancer occur in areas that can be reached by fingers. If you touch the anus with your fingers, you will feel some raised particles inside, which are hemorrhoids. If you feel that there is a cauliflower-like lump or an ulcer with a convex edge and a concave center in the intestine, you find that the intestinal cavity is narrow enough to accommodate only one finger; After the examination, it is found that there is blood, viscous liquid and mucus on the cuff of the finger, which is likely to be rectal cancer. You should go to the hospital quickly so as not to miss the treatment opportunity.
The difference between hemorrhoids and anal fissure is that anal fissure is accompanied by sentinel hemorrhoids, especially for patients who have been neglected for a long time. After developing into chronic anal fissure, it is often accompanied by external hemorrhoids and internal hemorrhoids. At this time, the characteristics of the two outside the anus are basically the same. Therefore, it is of great benefit to understand the difference between anal fissure and hemorrhoids and improve the vigilance against anorectal abnormalities.
The difference between anal fissure and hemorrhoid from pathological point of view
Anal fissure is mainly manifested as anal canal skin fissure and anal canal ulcer, which is not easy to heal.
Hemorrhoids are caused by varicose veins around anus, venous vessels and sliding mucosa at the lower end of rectum.
On the difference between anal fissure and hemorrhoids from symptoms
1. Anal fissure is mainly pain and bloody stool. Hemorrhoids are mainly bleeding, and only when the external hemorrhoids are red and swollen will hemorrhoids be severely painful.
2. Anal fissure can be seen as anal canal skin cracking, hemorrhoids are not. Anal finger examination can be confirmed, but anal fissure patients can not be examined by anal finger examination or endoscopy;
3. Anal fissure is often accompanied by anal papilla hypertrophy and anal papilloma, while hemorrhoids are not accompanied by anal papilla hypertrophy or papilloma;
4. When anal fissure occurs, the appearance of anus is narrow, while patients with hemorrhoids often see prolapse and eversion of internal hemorrhoids.
Anal pruritus and hemorrhoids.
Some patients with hemorrhoids have sticky secretions, which cause itching in the anus damp, but anal pruritus is not necessarily hemorrhoids.
Anal pruritus is a common local pruritus. The anus sometimes has slight itching, and if it is serious, it will become itchy over time. It is a common skin disease with local nerve dysfunction. Generally limited to around the anus, some can spread to the perineum, vulva or scrotum. Most of them occur at noon and in the old age of 20 ~ 40. At first, anal pruritus was mild, and there was no obvious change in anal skin, mostly paroxysmal. Chronic patients have severe itching, which lasts a long time, especially at night. Excessive scratching or mechanical stimulation makes perianal skin grow thick and rough, anal folds deepen, scratches, blood scabs and exudates are found in some areas, and feces and dirt remain in the folds. What's more, it may be complicated with infection with pustules or purulent secretions, flushing and swelling. After laboratory examination, diabetes, pinworm disease and candida albicans infection were found.
Clinical examination of anal pruritus may find that there are internal hemorrhoids, external hemorrhoids, mixed hemorrhoids and anal fistula at the same time.
Therefore, treatment should be given according to different situations.
