Anorectal examination is not troublesome. Routine examination can be roughly divided into three steps: inspection, digital examination, and anoscopy.
Inspect to see if there is any disease around the anal opening
In most cases, after you have presented your condition to your doctor, the first examination is an inspection. As the name implies, "inspection" is to see if there are any long things from the appearance, whether there is any change in color, whether there are cracks, discharge, etc. External hemorrhoids, perianal abscesses, anal fissures, perianal eczema and other diseases can be preliminarily judged by inspection because of changes in appearance.
About 80% of rectal cancers in China are discovered during "digital examination"
The second step is digital examination, which is called "digital anus examination" in full. It is one of the simplest and most effective methods in the examination of anorectal diseases. 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 situation 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, clearly judge the size and number of hemorrhoids
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. Through anoscopy, you can see the size, number, color of the mucous membrane, etc. of hemorrhoids, and make accurate judgments of hemorrhoids. I was in the St. Mark’s Hospital on Wednesday morning. If you or your family and friends encounter this type of problem, please come and talk to me.
What is an anoscope? It is a trumpet-shaped device about 6 cm 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 suffer pain.
Anoscopy can rule out hemorrhoids, proctitis, rectal ulcers and other diseases. Since colitis and other diseases of the colon start from the rectum and progress upward, anoscopy can not only observe the condition of the rectum, but also preliminarily determine the condition of the colon.
The above are three methods commonly used in anorectal examinations. In addition, there are a variety of inspection methods such as sigmoidoscopy, anorectal ultrasound, anorectal pressure measurement, and MRI. Each check is specific, and the doctor should make a judgment based on the condition of the doctor.
Here I would like to reiterate that once you find something growing near the anus, such as lower abdomen and anus drop, blood in the stool, pus, etc., do not delay, please go to the hospital for examination and treatment as soon as possible. In the early stage of illness, the condition is relatively simple, and the treatment is relatively simple. If the condition is delayed until it is severe, the pain will increase even more.
Finally, I wish everyone a healthy body!
