What is a LEEP Procedure?
A LEEP (Loop Electrosurgical Excision Procedure) is a treatment that uses a thin, electrified wire loop to remove abnormal or precancerous cells from the cervix, the lower portion of the uterus that opens into the vagina. The electric current heats the loop, allowing it to gently cut away a thin layer of tissue for diagnosis and treatment.
The removed tissue is then sent to a laboratory to check for precancerous changes or cancer, helping both treat abnormal cells and diagnose potential issues at the same time.
LEEP is typically performed in a clinic or office and usually takes 10–20 minutes.
Why is a LEEP Procedure Done?
LEEP may be recommended when cervical screening tests show abnormal cells or changes that could lead to cancer if not treated. Common reasons include:
To Diagnose or Treat Abnormal Cervical Cells
- Abnormal findings during colposcopy
- Moderate to severe cervical dysplasia (CIN 2 or CIN 3) (HSIL (High-Grade Squamous Intraepithelial Lesion) instead of CIN 2 or 3)
- Persistent abnormal cells after previous treatments (e.g., cryotherapy, laser therapy)
To Remove Cervical Growths
- Polyps (benign growths)
For Cervical Cancer Prevention
By removing precancerous cells early, LEEP can prevent them from progressing into cervical cancer.
What to Expect During the Procedure
A LEEP is performed similarly to a gynecological exam:
- Positioning: You lie on an exam table with feet in stirrups, just like during a Pap test.
- Speculum placement: A speculum is inserted to view the cervix. A colposcope will be used for magnification.
- Numbing medication: A local anesthetic is injected into the cervix. This may cause brief pressure or a stinging sensation.
- Excision of abnormal tissue:
- A thin wire loop with electrical current removes a layer of abnormal tissue.
- Sometimes more than one pass is needed.
- Stopping bleeding: The cervix is cauterized or treated with a solution to reduce bleeding.
- Duration: The actual removal often takes under 10 minutes; total visit time is around 20–30 minutes.
Risks & Possible Side Effects
While LEEP is generally safe, potential risks include:
Common Temporary Effects
- Mild cramping
- Watery, brownish, or lightly bloody discharge
- Fatigue or slight discomfort for a few days
Procedure Risks
- Infection
- Bleeding, sometimes heavier than spotting
- Cervical scarring (cervical stenosis), which may affect menstrual flow or future fertility
- Impact on future pregnancy, including a small increase in risk of preterm birth or low birth weight
When LEEP Should Be Delayed
LEEP may be postponed if you have:
- Cervicitis (cervical inflammation)
- Acute pelvic inflammatory disease
- Pregnancy, when possible
- Active menstruation
Preparation & Aftercare
Before the Procedure
- Avoid intercourse, douching, tampons, or vaginal medications for 24–48 hours beforehand.
- Tell your clinician about blood‑thinners, medications, or allergies (especially to latex, iodine, or anesthetics).
- A pregnancy test may be performed the day of the procedure.
- Schedule the LEEP for about one week after your period, if possible.
After the Procedure
- Mild cramping and discharge are expected for a few days; full healing takes 4–6 weeks.
- Use pads—not tampons—until healing is complete.
- Avoid intercourse, heavy lifting, and strenuous exercise as instructed (usually 3–4 weeks).
- Call your doctor if you develop fever, heavy bleeding, or foul‑smelling discharge.
LEEP is a quick, effective, and minimally invasive procedure used to remove abnormal cervical tissue before it becomes cancerous. It provides both diagnostic clarity and preventive treatment, making it one of the most valuable tools in cervical disease management. While generally safe, it's important to understand possible risks and follow aftercare instructions to ensure proper healing.
