Endoanal and endorectal ultrasound

This test involves taking ultrasound scan images of the back passage (endoanal) or lower part of the bowel (endorectal). They are usually performed to check for any defects in the back passage that may cause a degree of faecal incontinence, to check for any peri-anal abscesses or fistulas around the back passage or to assess any large or suspicious polyps in the rectum prior to consideration for a potential TAMIS procedure. The endoanal ultrasound is usually performed in conjunction with the anorectal physiology studies.

Before the procedure

This is a quick, simple, painless test that does not require any sedation or anaesthetic. Prior to the procedure you may sometimes need to take an enema if your rectum is not clear.

The procedure

The procedure is usually performed in the office or in the endoscopy department. Lying on your left side on an examination couch with your knees bent, the ultrasound probe (size of your finger) is used to take some ultrasound pictures inside your back passage or rectum. The procedure usually lasts approximately 30 min when performed with the anorectal physiology studies.

Recovery

After the procedure you should be able to immediately return back to normal activities. Your will be informed of any follow-up arrangements or further investigations or procedures required in relation to the findings from the tests.

There are no reported risks with this test.
