CHECKLIST AND BRING IT WITH YOU
What is Oesophageal Dilatation?
It is a procedure to widen the narrowing in your oesophagus. The first step is an endoscopy which you probably have experienced at an earlier date, but the procedure will take a few minutes longer as it is a little more than an inspection. In most cases you will be given a sedative.
The doctor will pass a slim flexible tube with a light on into your gullet (oesophagus) until it reaches the narrowing. In some patients a balloon dilator is used which is inserted into your gullet to the point of the narrowing and is then gently inflated to stretch your gullet. In other patients, a fine wire is passed through the endoscope into your stomach through the narrowing. The endoscope will then be removed leaving the wire in your gullet. The doctor will then pass the dilator over the wire and down to the narrowing. Firm but gentle pressure is used to push the dilator through the narrowing; this procedure is repeated using larger dilators until the narrowed area has been adequately stretched. Occasionally an X-ray may be required during the procedure. The procedure will take about 10 minutes.
Why Do I need Oesphageal Dilatation
You have probably been troubled by some symptoms, which have led to your doctor advising you to have treatment called an oesophageal dilatation to stretch the narrowing (stricture) in your gullet (oesophagus).
This will help relieve the swallowing difficulties you are experiencing. This procedure may have to be repeated periodically to enable food and fluids to pass through the gullet (oesophagus).
Can there be any complications or risks?
Perforation of the gullet
Oesophageal Dilatation carries a risk of perforation (hole) of the gullet. In most circumstances the risk is 1%, but there are reports of the risk reaching 10%. If this occurs, you may feel a pain in your chest or back, be short of breath and feel generally clammy and unwell.
If you have any of these symptoms YOU MUST CONTACT your doctor or the hospital Endoscopy Department or Ward 100 HRI (out of hours) as soon as possible.
Some people, for reasons we still do not fully understand, are particularly sensitive to the sedative drug. The breathing can be too shallow and too slow. In these cases we stop the examination, give more oxygen and if required we can give an antidote to reverse the effect of the sedation. This is usually all that is needed and the person recovers with no ill or lasting effects.
In some cases, when people have another serious illness e.g., heart disease, stroke, unstable angina, severe asthma or chronic bronchitis, the sedation drug can cause difficulty in breathing. This is rare and is why we monitor breathing and heartbeat throughout; and why we give oxygen by nasal tubes.
Common problems, which are not serious, include a haematoma (big bruise from your sedation needle) a sore throat and bloating.
What if I refuse to have the Oesophageal Dilatation?
This will not alter the manner in which we treat you and your standard of care will not change. However, it will be an important piece of information about your gastrointestinal tract that we will not have and you will not get the relief of your swallowing problem.
Please discuss this with your doctor/specialist team.
Who will do the procedure?
It will be a consultant or senior doctor who is trained and experienced in performing the procedure. Sometimes called an Endoscopist.
Where will the test be performed?
Oesophageal dilatation is mostly performed in the Endoscopy Department. Specially trained doctors and nurses work here and are very experienced in performing oesophageal dilatation and in the care it involves.
It will be done at Hull Royal Infirmary or Castle Hill Hospital depending on where your consultant is based. Please make sure you go to the correct Endoscopy Department. Directions will be given with your appointment letter. All the staff will help to make your stay as easy and dignified as possible. Please do not be afraid to ask questions.
How do I prepare for the procedure?
Please read the information leaflet. Share the information with your partner and family (if you wish) so that they can be of help and support. There may be information they need to know, especially if they are taking care of you following this examination. Complete the health questionnaire sent/given to you as fully as possible.
To allow for a clear view, your stomach and first part of your intestine needs to be empty.
You should not have any thing to eat and drink for at least 6 hours before your test. Do take any regular medicines up to this point.
If you have diabetes (especially taking insulin) or you have serious heart, lung or kidney problems, or concerned that a health problem you have may be affected, then contact the endoscopy department at the hospital you are having your examination (see contact numbers).
Warfarin – These are blood thinning tablets and usually have to be stopped for a period of time before your test, please contact your endoscopy department for advice.
Latex – Please inform the department if you have a confirmed latex allergy as this will affect your appointment time.
Creutzfeldt-Jakob disease/variant Creutzfeldt-Jakob disease (CJD) commonly known as mad cow disease – Please inform the department if you have been notified that you are at risk of CJD/vCJD for public health reasons.
Clopidogrel (Plavix) – Please inform the department if you are taking these tablets as these may need to be stopped prior to your procedure.
Pregnancy – It is important that you inform us if there is a possibility that you may be pregnant. Any information you share with us will be kept strictly confidential.
If you take any of the following blood thinning tablets please contact the Endoscopy Department before your appointment for further advice: Apixaban, Rivaroxaban, Dabigatran, Dabigatran, Argatroban or Edoxaban.
What happens to me in the Endoscopy Department?
Our friendly reception staff will greet you on arrival. They will let a nurse know that you have arrived. Occasionally there may be a delay in your appointment time due to any emergency taking place. If there are any delays you will be notified as soon as possible and be kept informed.
A nurse will collect you from the waiting room and explain what will happen next. You will be given an approximate time of when you may be collected to go home. It is advisable to leave any valuables at home.
We will ask you questions about your general health and work through the health questionnaire you have completed for us. Please feel free to ask questions.
The endoscopist will meet you and explain the test to you. You will both sign a consent form. This is to show you understand what will happen and agree to the procedure being performed. If you have any queries or worries, please tell us. We will check your blood pressure, pulse, oxygen levels and weight, before your test.
If you wear glasses or dentures, you will be asked to remove them.
You will be taken to the examination room and made comfortable on a bed on your left-hand side. To keep your mouth open, a plastic mouth guard will be placed between your teeth. A fine plastic tube will rest by your nostrils to give you some extra oxygen. A probe will be placed on your finger to monitor your oxygen levels and pulse rate.
Do I need sedation?
Yes. People have sedation to keep them comfortable while the doctor carries out the procedure. Sedation is given through a flexible needle in the back of your hand or arm. It makes you feel sleepy and relaxed but does not put you to sleep. You can still respond to what is happening.
Do I really need someone with me after sedation?
Yes, this is very important. The sedation given can have effects, which can last up to 24 hours after the test. You can become forgetful and also sleepy again.
Your test may be cancelled if you do not arrange to have someone to collect you and stay with you for the next 24 hours.
We strongly recommend that for the next 24 hours you:
- Do not drive
- Do not return to work or operate machinery
- Do not sign any important/or legal documents
- Are not left alone, you may be at risk of injuring yourself
- Are not left alone to care for children
If you are an outpatient, the person accompanying you will be contacted to collect you. If you are an inpatient you will be transferred back to your ward.
What happens when the test is finished?
You will need to rest on a trolley in the recovery room. We will check your blood pressure, pulse and temperature on a regular basis. You will need to stay in the department longer after this procedure so we can monitor you closely, you will then be helped to a chair and given a drink. Your relative or friend will then be contacted to collect you. It is quite likely that the back of your throat will feel sore for the rest of the day.
You may feel bloated if some air remains in your stomach. Both discomforts usually pass without any medication. Your swallowing may not appear to be improved or may seem worse for 1-2 days owing to the swelling of the tissues. You may find you have some streaks of blood in your saliva after the procedure this is quite normal and should stop without any further treatment.
When do I get the results?
The Recovery nurse will explain your results to you and (if you wish) the results will be told to your carer. They will be written on your discharge form with any instructions that you need to follow. If you wish, the nurse will repeat the result to you before you leave the department. Your own doctor or hospital doctor will receive a copy of the results.
Will I ever need an Oesophageal Dilatation again?
Yes, it is possible this procedure may have to be repeated periodically to enable food to pass down your gullet to your stomach.
If you have any further swallowing problems you can contact your Endoscopy Department directly for advice.

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.

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
