Introduction

This leaflet has been produced to give you general information.  Most of your questions should be answered by this leaflet. It is not intended to replace the discussion between you and the healthcare team, but may act as a starting point for discussion. If after reading it you have any concerns or require further explanation, please discuss this with a member of the healthcare team.

What is an Endo-anal Ultrasound?

You have probably been troubled by bowel symptoms for example; for example, constipation or faecal incontinence. Following discussion with your doctor, they have advised you to have an endo-anal ultrasound.

An endo-anal ultrasound assesses the anatomy of the anal canal. The examination will be performed using an ultrasound scanner placed within the anal canal. A picture will be generated which will allow identification of the muscles in the anal canal – this will then be used to help determine the best treatment for you.

Why do I need an Endo-anal Ultrasound?

The endo-anal ultrasound helps to identify if there are any problems with the muscles of the anal canal.

Women who have had a tear during the delivery of their baby often require an endo-anal ultrasound to assess the repair. The endo-anal ultrasound also gives your healthcare professional information that will help you both to determine the most appropriate way to deliver your next baby.

Can there be any complications or risks?

There are no known risks, or complications from an endo-anal ultrasound. Some patients find the procedure a little uncomfortable, although it should not be painful.

Patients who have a latex allergy are asked to inform the department before they attend so we can prepare the examination room.

Endo-anal ultrasound is not usually performed within the first three months of pregnancy. Please inform the department so an alternative appointment can be arranged if this applies to you.

How do I prepare for Endo-anal Ultrasound?

Please read the information leaflet. If you wish, share the information it contains with your partner and / or family so that they can be of help and support.

You are asked to complete a bowel diary and questionnaire before your appointment. The bowel diary should be completed for 7 days prior to your appointment – if you have a short notice appointment, please complete as many days as possible. The instructions for completion are on the form.

You can eat and drink as normal before your appointment.

What will happen?

You should go to the Department of GI Physiology, which is situated next to Ward 14 (1st floor) at Castle Hill Hospital.

You will be seen by a member of staff from the Department of GI Physiology who will be performing the endo-anal ultrasound.

You will be asked to remove your lower clothing and lay on your left side on the examination couch. The member of staff you see may conduct an examination of your anal canal and rectum before the investigation. The endo-anal ultrasound scanner will be inserted into the anal canal (approximately 5cm).  Several images will be taken which allows identification of the muscles of the anal canal. Once the endo-anal ultrasound scan has finished you will be able to get dressed and return to your normal activities.

You will not be sedated for your endo-anal ultrasound – you will therefore be able to travel or drive as normal.

The ultrasound should be completed within 5 – 10 minutes, although your complete appointment could take up to 30 minutes.

The above picture demonstrates where the ultrasound probe will be placed in the anal canal during the test.

What will happen afterwards?

You will be able to resume your normal activities after your endo-anal ultrasound.

You will be sent an appointment to discuss your results from your referring consultant / healthcare professional.

Should you require further advice on the issues contained in this leaflet, please do not hesitate to contact the Department of GI Physiology on telephone (01482) 624036.

General Advice and Consent

Most of your questions should have been answered by this leaflet, but remember that this is only a starting point for discussion with the healthcare team.

Consent to treatment

Before any doctor, nurse or therapist examines or treats you, they must seek your consent or permission. In order to make a decision, you need to have information from health professionals about the treatment or investigation which is being offered to you. You should always ask them more questions if you do not understand or if you want more information.

The information you receive should be about your condition, the alternatives available to you, and whether it carries risks as well as the benefits. What is important is that your consent is genuine or valid. That means:

• you must be able to give your consent
• you must be given enough information to enable you to make a decision
• you must be acting under your own free will and not under the strong influence of another person
