Many people in the population will suffer from anorectal diseases, but it is generally unclear what doctors will do when they visit the doctor, and they are not psychologically prepared. In fact, the anorectal examination is not troublesome. Routine examination can be roughly divided into three steps: inspection, digital examination, and anoscopy.
The main purpose is to observe whether there are any lesions around the anal orifice. In most cases, when you state your condition to the doctor, the first examination is inspection. As the name implies, "inspection" is to see if there are any long things from the appearance, if there is any change in color, if there are cracks, discharge, etc. External hemorrhoids, perianal abscesses, anal fissures, perianal eczema and other diseases can be preliminarily judged by inspection because they may cause changes in appearance.
2. Finger examination:
About 80% of rectal cancers in China are found during “digital examination”. The full name is “digital anus examination”, which is one of the simplest and most effective methods for anorectal disease examination. Digital diagnosis is the doctor touching the patient's anus with his fingers. Because of its strong intuitiveness and reliability, it can detect many early lesions of the anorectum in time. According to statistics, about 80% of rectal cancers in China are discovered during digital examinations. Digital examination can test the anal skin for pain, touch, and temperature. Intra-anal palpation can also assist in checking the behavior of anal fistula, the relationship between the fistula and the rectal ring, the tension of the sphincter, and even the condition of adjacent organs. Digital examination can also know whether there are problems in the rectal cavity, whether there are papillomas, polyps, hard masses, and infections.
Anoscope is also a simple examination, which can be completed in one minute, and the examinee will not have any pain. Why do anoscopy? It is an effective supplement to digital diagnosis. Although the digital examination is good, it can only exclude tumors, but no hemorrhoids can be seen. Because hemorrhoids are soft, hard masses cannot be felt during digital examination, especially when hemorrhoids are not very large, they may be ignored. And through anoscopy, you can see the size, number, color of the mucous membrane, etc. of hemorrhoids, and make accurate judgments of hemorrhoids.
What is an anoscope? It is a trumpet-shaped device about 150px long. It enters the intestine from the anus to observe whether there are erosions and bleeding points in the intestine, whether the mucosa is normal in color, whether it is loose, whether there are raised hemorrhoids, whether there are ulcers... Anoscopy is simple and easy to perform, does not require complicated equipment, does not damage the organs, and the subject will not be painful. Anoscopy can rule out hemorrhoids, proctitis, rectal ulcers and other diseases.
4. Other inspection methods
The above are three methods commonly used in anorectal examinations. In addition, there are a variety of inspection methods such as sigmoidoscopy, anorectal B-ultrasound, anorectal manometry, fiber colonoscopy, MRI and so on. Each check is specific, and the specific needs to be done should be judged by a specialist based on the condition.
