Loop electrosurgical excision procedure (LEEP) uses a thin wire loop to cut out areas of the cervix. The cervix is the lowest part of the uterus. The Loop allows precise cuts.
Problems from the procedure are rare, but all procedures have some risk. Your doctor will review possible problems, like:
The doctor will talk about ways to manage risks. Factors that can increase your risk of problems include:
The following may also increase the risk of complications:
Talk to your doctor about your medicine that you take. You may be asked to stop taking some medicine up to 1 week before the procedure.
The day of the procedure:
Local anesthesia is often used for a LEEP. It will numb the area, but you will be awake. The anesthesia may be applied as 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 area. It will highlight abnormal cells. A thin wire will be inserted into the vagina toward the cervix. The abnormal tissue will be removed with the thin wire. The tool heats the area to stop bleeding from blood vessels. 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.
You will be allowed to rest. When you are ready, you can go home.
It will take a few weeks for the area to fully heal. Most can return to normal activity in a few days.
After arriving home, contact your doctor if any of the following occurs:
If you think you have an emergency, call for emergency medical services right away.
