MyoSure Hysteroscopy
This patient information leaflet aims to give you some information about the MyoSure hysteroscopy and also to help answer some questions that you may have. It is a guide and there will be an opportunity to discuss the treatment with the doctor at your appointment. We hope by increasing your understanding of the treatment you will feel less anxious when you come to clinic.
Where are we?
The Hysteroscopy Clinic is situated in the Gynae / Antenatal Clinic.
You may wish to bring a friend or relative to accompany you and take you home. They can be present during the examination if desired.
Why is MyoSure hysteroscopy performed?
MyoSure is a treatment for women who have heavy or irregular bleeding due to polyps or fibroids that have already been confirmed during a diagnostic hysteroscopy. A polyp is a small lump of tissue that can grow on the lining of the uterus. A fibroid is a growth of uterine muscle.
What is MyoSure hysteroscopy?
A hysteroscopy is an investigation where a small telescope is passed through the neck of your womb (cervix) to examine the inside of your womb (uterus). MyoSure is a procedure performed under local anaesthesia which allows your doctor to look inside your womb and remove any polyps or fibroids. This is done by inserting a small tube with a telescope at the end (hysteroscope) through the vagina and into your uterus. The MyoSure device is passed down the hysteroscope and the polyp or fibroid can then be removed.
It does not require an incision (cut) and can be performed in an outpatient setting using local anaesthetic. Alternatively, it can be performed as a day case procedure under general anaesthetic, but this would need to be arranged to take place on another day.
Prior to the appointment:
- If you are on blood thinning medication, please telephone the gynaecology secretaries on 01229 402503.
- It is advisable to use barrier contraception (like condoms) from the start of your period before the procedure and continue using them until after you have had the procedure.
If you have any worries or concerns before the procedure, please ring and ask to speak to a member of the hysteroscopy team. Contact details are at the end of the leaflet.
On the day of the procedure:
Eat something light before attending your appointment.
- If you are able to take ibuprofen or paracetamol, you are advised to take 400 mg of ibuprofen or 1 gram of paracetamol, 1 hour before the procedure (both medications are easily bought at supermarkets and chemists). Some people take both which is not a problem.
- If you are allergic to ibuprofen or similar pain relief (such as naproxen or aspirin) or are not able to take these for any reason, please check with your GP for a suitable alternative.
- If you are already taking paracetamol and / or ibuprofen regularly you will not need to take extra. Just continue with your normal dose.
- Bring a sanitary towel with you if you can. However, we can provide one if you do not have any.
- You may wish to bring a friend or relative to accompany you during the examination.
- Please provide a urine sample before we start the hysteroscopy, as it is important there is no risk of pregnancy when the procedure is carried out. Therefore, if you are of childbearing age, we will ask your permission to carry out a urine pregnancy test before we start. Your procedure will be cancelled if there is a possibility that you might be pregnant.
What will happen to me?
On the day of your appointment you will see the doctor before the procedure for an assessment. This is a good time to raise any concerns or questions you may have, as it is important to us that you are involved in any decisions about your care and treatment.
The doctor will need to gain your consent before starting the procedure so you will be asked to sign a consent form if this hasn’t already been done at a previous appointment. You will be shown into the treatment room. A nurse and a health care assistant will be with you to ensure your comfort and help the doctor doing the procedure. Please note that we
are a teaching hospital so it is not unusual for trainee doctors or student nurses to be present during your appointment. If this makes you feel uncomfortable then do not hesitate to tell the nurse or doctor.
You will be asked to remove the bottom half of your clothing behind a curtain cubicle and to cover yourself with a sheet. You will be required to lie down on an examination couch for the procedure.
The doctor will insert a speculum into the vagina (similar to a smear test). This will enable access to your cervix.
A local anaesthetic is then injected into the cervix and the opening gently stretched. This is to allow the hysteroscope to pass through the cervix and into your womb.
A sterile saline fluid is also introduced via the hysteroscope into the womb to distend it (enlarge the space) to make it easier for the doctor to see. You may feel some of that fluid coming out of your vagina during the procedure. This is normal.
What can I expect during the procedure?
The hysteroscope has a camera attached and images of the inside of your womb are sent to a screen by the side of the bed, which can be viewed by the doctor and yourself. Pictures will be taken at the time of the procedure as a record for your medical notes.
The MyoSure device is then passed into the womb and held against the polyp or fibroid which is then cut away and sent for further examination.
The results of this can take anything between 2 - 4 weeks to reach you depending on urgency.
We are more than happy for you to bring a partner, friend, or relative with you to the appointment for support and they can even sit with you during the hysteroscopy if you wish. It is important to note that you will be involved at all times during the procedure and if at any point you would like the doctor to stop or have any concerns or queries please say
or ask.
In total your appointment will take about 45 minutes which includes the discussion with your doctor. However, as is the nature of hospital appointments, sometimes appointments may be late or overrun, so please allow yourself additional time.
Are there any risks of the procedure?
There are risk with any operation, but these are small. Possible complications are:
- Bleeding
- Infection
- Perforation of the uterus (making a hole in the womb). In most cases when a perforation occurs you may require admission and antibiotics treatment and this resolves without any further treatment. Rarely you may require further sugery to repair any nearby local organs but this is very unlikely.
If you develop:
- High temperature or strong smelling discharge.
- Lower abdominal pain.
- Heavy bleeding that is worse than a normal period or you are at all concerned then please contact your GP or Gynaecology Clinic for advice (contact details are at the end of this page).
After care:
There may be some slight bleeding over the next few days. This should not be heavier than a period and should gradually get less, becoming a brown discharge before it stops. You are advised to use sanitary towels rather than tampons while you have any bleeding or discharge.
You may experience some period-type pain for the next few days. Please take pain relief if required.
You are advised to avoid vaginal intercourse until the discharge stops.
If you find you have an increase in temperature, pain, offensive vaginal discharge, or heavy bleeding, after the hysteroscopy you should contact your GP or hospital for advice.
If you had a biopsy taken we will write to you with the result, but it may take up to 6 weeks. If you require a further appointment, it will be sent through the post.
