Examination Under Anaesthetic (EUA)
WHAT IS AN EXAMINATION UNDER ANAESTHETIC?
An examination under anaesthetic (EUA) is an internal examination of your lower bowel carried out in an operating theatre under general anaesthetic.
Your consultant may recommend this procedure if he or she feels they need to make a more thorough examination than can be done in clinic. Under anaesthetic, your muscles are more relaxed and it is much easier for the surgeon to make a thorough and accurate assessment of your bowel.
Depending on your condition, the surgeon may take biopsies (tiny pieces of bowel tissue) to help with diagnosis.
WHAT PREPARATIONS SHOULD I MAKE?
Because you will be having a general anaesthetic, this is like preparing for any other operation. You will be given a pre-admission health check, and the hospital will advise you on exactly when to stop eating and drinking before your operation.
After the operation you should feel well enough to go home the same day, but you must not drive for at least 24 hours after your operation and you should arrange for someone to take you home and to stay with you overnight.
WHY HAPPENS DURING THE TEST?
As with every general anaesthetic, there is a risk of side effects such as nausea and vomiting or sore throat, and a very small risk of potentially serious problems such as allergic reaction or heart or lung problems. These will be explained to you by your anaesthetist and you will be asked to sign a consent form once you are happy that you understand the risks.
You may experience some pain or a small amount of bleeding from the rectum, especially if you have had biopsies taken. This should settle down within a day or two.
