It is now possible to see inside the womb to investigate women having heavy periods or irregular bleeding. Previously, a blind technique and a scrape (D &C) was used, resulting often in unsatisfactory results. Using no cuts, a small telescope is inserted into the cavity of the womb through the vaginal route. It has a small video camera attached which allows the enlarged picture from the telescope to be seen on a television screen. The procedure can be performed under a local or general anaesthetic, usually as a day case or outpatient procedure. Treatment, if needed, can usually be carried out at the same time, saving time and with excellent results.
You may be having heavy periods, not settling with usual medications or with irregular bleeding (Intermenstrual Bleeding). This needs investigation, especially if you are above the age of 40. This is one of the most common procedures performed in Gynaecology, and can be used for both diagnosis and treatment A hysteroscopy is a telescopic examination which allows the lining of the womb to be inspected, thereby identifying anything that might be causing your problem (e.g. a polyp). A sample or a biopsy (removing of a few cells from the lining of the womb) is usually taken to allow further analysis by a pathologist.

You will usually be discharged home in a few hours after your operation or the following morning, dependent on how you feel.
Yes, if you are having a General anaesthetic, no food, even chewing gum for at least 6 hours before your procedure.
Evening Operation: No food or chewing gum after 10 am in the morning. You can drink water up to midday.
Morning Operation: No food or chewing gum after midnight before your procedure You can drink water up to 6 am of the morning of your procedure. Please take your essential medications as normal with a sip of water, unless advised by nurse or doctor.
You normally should not stop any of your essential medications. Please take your usual essential medications with a tiny sip of water at the regular time. Do remember to bring a list of all your medications to show the nurse at your pre-assessment (if you are having one) and also let your admitting nurse and anaesthetist know all the medications you are on. This is because your medications may influence your anaesthetic and surgery. You should also inform the nurse and anaesthetist of any allergies that you have to foods, metals, drugs etc. Some important notes on certain conditions are listed below.
DIABETES (insulin or tablet)
In general you should not take your insulin injection or your tablet, when you are fasting. For example, if your operation is in the morning, DO NOT TAKE your morning dose or injection as you will be fasting overnight, but do take the previous dose as normal. If your operation is in the evening, take your doses as normal in the morning, but stop injection/tablets if you are taking any at lunchtime (you will fast for 6 hours, usually after 10 am).You can resume your normal regime, once you are eating and drinking normally. If in any doubt, consult your surgeon or anaesthetist.
ASPIRIN, WARFARIN, CLOPIDOGREL, CLEXANE or any blood thinning agent
You will need to stop most blood thinning agents such as Aspirin or Clopidogrel at least 1-2 weeks before your procedure. This is to avoid excessive bleeding at your operation. If you are on Warfarin or Clexane, you will need to liaise with your surgeon and cardiologist. If in any doubt, consult your surgeon or anaesthetist and certainly inform them when you see them, as it may influence your management.
- Vaginal bleeding: Some amount of vaginal bleeding and discharge is to be expected, usually for a week or so. As long as this is not heavy, or has an offensive smell or causes you concern, this is normal. It is usual to have some slight bleeding after a hysteroscopy and you may need to wear a sanitary towel for a couple of days. Avoid tampons, usually for 2 weeks after the procedure, to reduce risk of infection.
- Pain: Some women may experience slight lower abdominal discomfort. You can take your usual painkillers (such as Paracetamol or Ibuprofen) if you think it necessary.
- Nausea: You may feel slightly nauseated or groggy just as you are coming out of your anaesthetic. This will pass soon and if needed, medication will be given to you to make you feel better.
- Work: You will be able to resume normal activities soon. Returning to work You will be able to go to work the next day or as soon as you feel able.
- Sexual Intercourse: You will be able to resume sexual intercourse the next day or when you feel comfortable.
- Other physical activities: You will be able to resume other activities such as sport and swimming as soon as you feel able.
Hysteroscopy is a very safe procedure, but like any other operation, comes with some small risks. There may be a risk of infection, heavy bleeding or perforation (damage to womb) but are uncommon and usually occur in less than one in a hundred cases.
Following your hysteroscopy, the findings and their implications will be discussed with you. Plans will be made for any further treatment and any necessary appointments will usually be made before you leave the hospital. The results of the biopsy take about a week to come back. You will usually be seen in clinic for a follow up or have the results communicated to you. If you need further surgery or other treatment, this will be discussed in detail with you, usually in the clinic. Your GP will be sent a letter with the findings from your procedure, and any results. You can be copied into this, if you so wish.
