Visual confirmation of hemorrhoids can be done by doing an anoscopy, using a medical device called an anoscope. This device is basically a hollow tube with a light attached at one end that allows the doctor to see the internal hemorrhoids, as well as polyps in the rectum.

If warranted, more detailed examinations, such as sigmoidoscopy and colonoscopy can be performed. In sigmoidoscopy, the last 60cm of the colon and rectum are examined whereas in colonoscopy the entire bowel is examined.

A pathologist will look for dilated vascular spaces which exhibit thrombosis and recanalization.
