Introduction to anorectoscopy Anorectoscopy is a speculum to examine the rectum, also called anoscope or proctoscope. It is about 5~10CM long and 2~3CM in diameter and has different shapes such as straight, flared, lobed, or oblique, but the most commonly used are still straight and flared. Nowadays, disposable plastic anoscopes are mostly used. Anoscopy is mainly used to observe and understand the situation in the anus and rectal jug abdomen. In patients with hemorrhoids, anoscopy can reveal the size and shape of the nucleus at the site of internal hemorrhoids, and whether there is congestion, erosion, edema, and bleeding spots on the mucosal surface of the hemorrhoids. In addition, it is possible to find out the presence of anal papillary hypertrophy, polyps, ulcers, malignant tumors, etc. in the anus and rectal jug abdomen, and to observe the presence of accumulated blood and mucus in the intestinal cavity and the looseness of the rectal mucosa. During the examination, the doctor will apply paraffin oil to the outer layer of the anoscope, massage the anal margin with the end of the anal lens to relax the anus, and then slowly insert it into the anus in the direction of the umbilicus and remove the core for observation. In order to minimize the impact on the examination and the discomfort caused by the examination, the patient should empty the stool and urine before the anoscopy, do not be nervous during the examination, relax the whole body, especially relax the anal area, do not tighten both sides of the buttocks, it is better to take a big breath during the insertion of the anoscope, and do not retract the body or contract the abdomen after the insertion of the anoscope. It is also advisable to bring some paper for wiping out the lubricant or stool left after the examination, etc. Patient’s examination position: 1, knee-chested: suitable for examination of male patients, especially for the examination of the prostate and seminal vesicles, and is also a better position for the examination of the anus and rectum. 2, left horizontal: suitable for examining female patients, male patients can also be used. 3, supine: with abdominal cavity disease or not easy to change position can be used in this style, especially for the physically weak.
