Alternate Names : Biopsy - rectum
A rectal biopsy is a procedure to remove a small piece of rectal tissue for examination.
Why is the Test Performed?
A rectal biopsy is used to determine the cause of abnormal growths found during anoscopy, sigmoidoscopy, or other tests. It can also be used to confirm the diagnosis of amyloidosis.
How is the Test Performed?
A rectal biopsy is usually part of anoscopy or sigmoidoscopy.
A digital rectal exam is done first. Then, a lubricated instrument (anoscope or proctoscope) is placed into the rectum. You will feel some discomfort when this is done.
A biopsy can be taken through any of these instruments.
How to Prepare for the Test?
You may get a laxative, enema, or other preparation before the biopsy so that you can completely empty your bowels.
How will the Test Feel?
There will be some discomfort during the procedure, and you may feel an urge to have a bowel movement. Cramping sometimes occurs as the instrument is placed into the rectal area.
