Since the main symptoms of hemorrhoids are bleeding, prolapse, pain and incomplete defecation related to defecation, there are many clinically large intestine and anus diseases that can produce the above symptoms or similar symptoms, especially the anus and large intestine Malignant tumors, if they are treated as hemorrhoids, will delay the diagnosis, lose the opportunity for radical treatment, or produce complications and other extremely serious consequences. Therefore, it is necessary to distinguish hemorrhoids from other anorectal diseases to facilitate correct treatment.
⑴Anorectal cancer──is one of the most common malignant tumors of the digestive tract. Because it is also mainly manifested by stool bleeding, it is easy to mistake it for hemorrhoids in the early stage. However, the bleeding caused by anorectal cancer is dark red bloody stools with mucus, occasionally pus and bloody stools, while hemorrhoids are mostly bloody stools. Doctors can make clear through digital rectal examination, anal examination, barium enema examination, and colonoscopy. The diagnosis.
⑵Rectal polyps-common in children, the main symptoms are blood on the surface of the stool or polyps protruding from the anus. Since children rarely produce hemorrhoid bleeding symptoms, polyps should be considered first in children with blood in the stool. Adults can also get rectal polyps, but the symptoms are more variable, with or without bloody stools and other symptoms, which are more likely to be confused with hemorrhoids, especially because adult polyps are more malignant, so you should go to the hospital for diagnosis and treatment in time.
⑶ Anal fissures──There may also be blood in the stool, manifested as a small amount of blood in the stool after defecation, but its characteristic symptoms are severe anal pain during and after defecation, and often obvious symptoms of constipation. The typical triad of anal fissures is hypertrophy of the anal papilla, anal fissure and sentinel hemorrhoids, which are generally easily distinguished from hemorrhoids. It should be noted that some patients may have both diseases at the same time and should be treated together.
⑷Anal and rectal prolapse──refers to the downward displacement of the skin of the sigmoid colon, rectum, and anal canal. Simple mucosal prolapse is incomplete prolapse, and full-thickness prolapse is complete prolapse. In general, mucosal prolapse is easily confused with internal hemorrhoids or circular mixed hemorrhoids. In fact, advanced circular mixed hemorrhoids are often accompanied by prolapse of rectal mucosa and anal skin; in general, hemorrhoids are often accompanied by obvious bleeding or hemorrhoid thrombosis Symptoms such as incarceration and incarceration, while anorectal prolapse is less likely to have bleeding symptoms. Only when the prolapsed mucosa is incarcerated, necrosis, or erosion will dark red blood seep out.
⑸Anal sinusitis and anal papilla hypertrophy──When acute inflammation of the anal sinus occurs, significant anal irritation and burning sensation can occur. Due to the increased pain during defecation, mucus and a small amount of blood are often present; when chronic inflammation occurs Anal pain or discomfort after defecation, a few have radiating pain in the sacrococcyx or perineum, and the anal papilla can gradually increase with inflammation and prolapse out of the anus. Therefore, the former is easily confused with internal hemorrhoids and inflammatory internal hemorrhoids, while the latter is easily confused with internal hemorrhoids prolapse.
⑹Perianal abscess ── In the acute stage, it is usually accompanied by local redness, swelling, heat and pain in the anus and perianal area, as well as the falling of the anus, incomplete defecation, tenesmus, and often accompanied by systemic symptoms such as chills and fever. General anal examination can There is obvious swelling and tenderness, which can be diagnosed by puncture, which should be distinguished from hemorrhoid incarceration and thrombotic inflammatory edema.
⑺ Condyloma acuminatum ── caused by a virus, related to sexual infection, local long-term uncleanness or secretion stimulation, it grows on the skin of the perianal anal canal. It is a papillary bulge of different sizes, papillary, mushroom-like or cauliflower-like, roots They often have stalks, grow in groups or overlap. Symptoms include anal itching, mild pain, bleeding, and odorous secretions, which should be differentiated from external hemorrhoids.
