Loop electrosurgical excision procedure
(LEEP) uses a thin wire loop to precisely cut out areas of the cervix. The cervix is a neck-like structure that connects the vagina and uterus. LEEP is done to remove abnormal cervical cells.
LEEP is often done after abnormal
cells have been found on the cervix. These abnormal cells are often found on a
Pap test. If the cells found on a Pap test show
(abnormal cells) or cancer cells, a LEEP may be done.
Problems from the procedure are rare, but all procedures have some risk. Your doctor will review potential problems, like:
Before your procedure, talk to your doctor about ways to manage factors that may increase your risk of complications such as:
The following may also increase the risk of complications:
Talk to your doctor about your medications. You may be asked to stop taking some medications up to 1 week before the procedure.
The day of the procedure:
Local anesthesia is often used for a LEEP. This will keep you from feeling pain during the procedure. You will be awake during the procedure. The anesthesia may be applied with a lotion or injected into the area.
You will lie on your back on a table with your feet up in footrests. A speculum will be inserted into your vagina. This tool will separate the vaginal walls. This will allow the cervix to be viewed. Anesthesia will be applied to the cervix to numb the area.
A solution will be applied to the cervical area. The solution will show the abnormal area that needs to be removed. A thin wire will be inserted into the vagina toward the cervix. You will hear a vacuum-like noise. You may also hear a humming noise. The thin wire loop is like a surgical knife. The abnormal tissue will be removed. You will need to stay still. The area will be cauterized. This process heats the blood vessels to stop bleeding. A paste may also be applied to stop bleeding.
LEEP only takes a few minutes.
You may feel cramping during LEEP. You should not feel any sharp pain.
Your blood pressure and heart rate will be checked.
