In the anaesthetic bay of the operating theatre, a small plastic tube (called a cannula) will be placed into a vein in your arm or hand.
The cannula is used to administer intravenous sedation, which is the first stage of your general anaesthetic. Once it has taken effect, you'll be taken to the operating theatre.
You'll be placed on the operating table on your back with your legs spread apart and your feet and knees supported in stirrups.
Before the procedure, your vulva will be cleansed using an antiseptic solution. A speculum – a metal instrument used to keep the vaginal walls apart – is inserted so there is a clear view of the cervix. The canal of the cervix is gently stretched open allowing the hysteroscope to be inserted. Saline may be injected via the hysteroscope to expand the inside of the uterus, as the walls of the uterus normally sit together.
A video monitor is used so the surgeon can examine the uterus to see if there are any abnormalities.
If abnormalities are found, or already known to be present, your surgeon may do an operative hysteroscopy. This is done by passing surgical instruments through the fine channels inside the hysteroscope, and using either very small scissors or diathermy (electrical current) to remove any abnormal growths. If needed, a biopsy of the uterus lining can be taken and sent to a pathologist for examination.
