Hemorrhoids are relatively simple to examine and can be judged after anal visual inspection. Except for stage I internal hemorrhoids, stage II or above patients squat to do defecation, the hemorrhoids will prolapse and the size and location of the hemorrhoids can be observed, but the prolapse is not obvious when the patient’s anus is slightly tight and not easy to see. After rectal examination, we can understand whether the rectal mucosa is smooth, whether there are swellings, and whether there are polyps. Rectal finger diagnosis is very important to exclude tumors in the middle and lower rectum, and proctoscopy to observe the rectal mucosa, whether there is bleeding, whether there is anal papillary hypertrophy, and whether there are tumors and polyps in the rectal canal.
