WELCOME TO MACARTHUR SURGICAL GROUP
Anorectal physiology testing involves a series of tests that assess the strength and sensation of your anal sphincter muscles and the rectum
Why is anorectal
manometry performed?
Anorectal physiology testing including manometry is used to identify pelvic floor abnormalities which can cause constipation and faecal incontinence. Severe forms of these conditions can be debilitating and lead to poor quality of life. If pelvic floor dysfunction is identified, pelvic floor physiotherapy or anorectal biofeedback therapy can help treat these symptoms.
Sometimes, anorectal physiology testing is also used to assess the function of the anal sphincter after a severe injury sustained during vaginal delivery.
How is anorectal
manometry performed?
You will be asked to remove your lower clothing and lie on your left side with your knees bent up to your chest. Firstly, you will be examined with a gloved finger. Then a small probe will be placed into your anus (about the width of a pen). Your sphincter muscles will be tested by asking you to rest, squeeze and bear down or push. A small balloon attached to the probe will be inflated to test your sensation (feeling) as this can be abnormal.
Endo-Anal Ultrasound
An ultrasound of the anal sphincter muscles can be performed by inserting a different probe (about the width of a finger) into your anus.
​
Pelvic floor problems can be quite complex, and these tests can all contribute to providing our specialists with important information related to the function of your bowel and pelvic floor.
How should I prepare for anorectal manometry?
No form of bowel preparation including enemas or suppositories are required prior to the procedure.
You will also not need to fast prior to anorectal physiology testing.
As anorectal physiology testing does not require any sedation or anaesthetics, you will be able to drive
both prior to and after your appointment.
