Hemorrhoids are a shameful and painful disease. It has made countless moments that could have been “flying free” into difficult moments that have lasted like years. As the saying goes, “nine out of ten hemorrhoids”, but in fact, “ten out of ten hemorrhoids” is not an exaggeration, because the rest of that one may not have found out that they have hemorrhoids. In fact, the so-called hemorrhoids are swollen or stagnant venous plexus in the anal canal or lower end of the rectum, resulting in easy release from the anus during defecation or bleeding, pain, anal itching and so on. Clinically hemorrhoids are divided into internal hemorrhoids, external hemorrhoids, mixed hemorrhoids three types, external hemorrhoids are more obvious, can be directly touched or see; and internal hemorrhoids and part of the mixed hemorrhoids on the relatively hidden, need to carry out the relevant examination in order to find out; that what are the relevant examination? (1) Rectal Finger Examination Rectal Finger Examination Schematic Diagram Rectal Finger Examination means that after the doctor puts on the finger cuffs or gloves, the index finger is smeared with lubricant, and extends into the rectum from the anus, touching the inner wall of the rectum to check whether there are bulges and bulging organisms. If no mass or bulge is found on rectal palpation, anoscopy will be recommended to the patient for a better view of the rectal lining. Rectal examination is a relatively simple and intuitive clinical examination, but if the patient has anal stenosis or severe pain, the patient needs to avoid the examination. (2) Anoscopy Schematic diagram of anoscopy Anoscopy is a device or instrument used to examine anal and intestinal lesions, and is a commonly used tool for anal and intestinal examinations, including traditional anoscopy and electronic anoscopy. Before performing anoscopy patients should first undergo rectal palpation, then the tip of the anoscopy is first coated with lubricant, then the right hand holds the anoscopy and holds the core with the thumb, and with the left thumb and forefinger the right buttock is pulled open to show the anal opening, and the anal rim is massaged with the anoscopy lens part to relax the sphincter muscle, and then it is inserted slowly in the direction of the umbilicus. (3) Colonoscopy Schematic diagram of colonoscopy Hemorrhoids patients are generally carried out electronic colonoscopy, that is, through the electronic camera probe installed in the front of the colonoscope will be the image of the colonic mucosa image transmission in the processing center will be displayed on the screen after the image of a medical device, can be clearly observed to the colorectal mucosa of the subtle changes, such as inflammation, celiac disease, ulcers, bleeding, polyps, cancer and so on. Its image is clear and realistic. In addition, if you encounter can lesions, you can also send biopsy forceps through the instrument channel of the colonoscope to take out the tissue of the size of a grain of rice, and the pathology section for examination to determine the nature of the lesion, but also for the treatment of microscopic polyps, haemostasis, localization of the lesion markers, special staining treatment, and so on. Not only for the diagnosis of hemorrhoids has significance, for diseases other than hemorrhoids also has positive significance. The above examination is of great significance to the diagnosis of the disease, so pay attention to the following precautions, and strive to make the examination smoother and more effective. 2, check the precautions Before doing the various checks and inspections, the patient should pay attention to try to empty urine and feces, take the lateral position or truncated position, and test the tightness of the sphincter muscle before the examination. Try to relax during the examination, do not be too nervous, cooperate with the doctor to carry out some operations or actions can be.
