As we all know, anorectal disease is an “export” problem, which makes people think, in the anorectal department to do the examination will not be very complicated? After all, it’s not like the stomatology department where you can open your mouth. In fact, the anorectal examination is not a problem, the routine examination can be divided into three steps: visual examination, finger diagnosis, anoscopy. Visual examination to see if there are lesions around the anal opening In most cases, the first examination is visual examination after you present your condition to the doctor. As the name implies, “visual examination” is to see if there is any growth, color change, fissure, pus, etc. External hemorrhoids, perianal abscesses, anal fissures, perianal eczema, and other diseases can be initially determined by visual examination because they cause changes in appearance. About 80% of rectal cancers in China are detected during “finger diagnosis” The second step is finger diagnosis, which is one of the easiest and most effective methods of anorectal disease examination. Finger palpation is the touching of the patient’s anus with the doctor’s finger, which can detect many early anorectal lesions in time because of its strong intuitiveness and reliability. According to statistics, about 80% of rectal cancers in China are detected during finger diagnosis. Finger palpation can test the anal skin for pain, touch and temperature, and intra-anal palpation, and can also assist in checking the path of anal fistula, the relationship between fistula and rectal ring, the tension of sphincter muscle, and even understand the condition of adjacent organs. Finger palpation can also find out if there are any problems in the rectal cavity, whether there are papillomas, polyps, hard masses, foci of infection, etc. Anoscopy to clearly determine the size and number of hemorrhoid nuclei Anoscopy, too, is a simple test that takes only one minute to complete and is painless for the person being examined. Why is anoscopy necessary? It is a useful complement to finger palpation. Although finger palpation is good, it can only rule out tumors, but not hemorrhoids. Because hemorrhoids are soft, hard masses cannot be felt during finger palpation, especially when the nucleus is not very large and is likely to be overlooked. Anoscopy, on the other hand, allows you to see the size and number of hemorrhoid nuclei, the color of the mucosa, etc., and make an accurate judgment about hemorrhoids. What does an anoscope look like? It is an approximately 150px long, flared device that enters the intestine through the anus to observe whether there is erosion and bleeding spots in the intestine, whether the mucous membrane is normal in color and loose, whether there are raised hemorrhoid nuclei, and whether ulcers occur. …… Anoscopy is easy to perform, does not require complicated equipment, does not damage organs, and is The anoscopy is easy to perform, does not require complicated equipment, does not damage the organs, and is painless for the person being examined. Through anoscopy, diseases such as hemorrhoids, proctitis, and rectal ulcers can be ruled out. Since colitis and other colonic disorders also develop from the rectum upward, anoscopy can not only observe the rectum, but also make a preliminary determination of the condition of the colon. These are the three common tools used in anorectal examinations. In addition, there are also sigmoidoscopy, anorectal ultrasound, anorectal manometry, MRI, and other examination methods. Each of these tests is specific, and the doctor should give a judgment on which one is needed according to the condition. I would like to reiterate here that once you find something growing near the anus, with a small abdomen and anal drop, blood in the stool, or pus flowing, do not delay, please go to the hospital for examination and treatment as soon as possible. In the early stage of the disease, the condition is relatively simple and the treatment is relatively easy. If the condition is delayed until it becomes serious, the pain will be increased even more. Finally, I wish you all a healthy body!
