Conization in Turkey, Prices of Istanbul Clinics

What is cervical conization?

Cervical conization, also called a cone biopsy, is a gynecological surgical procedure in which a cone-shaped section of tissue is removed from the cervix. The procedure is indicated when a Pap smear, colposcopy, or directed biopsy reveals precancerous changes in cervical cells, typically caused by persistent Human Papillomavirus (HPV) infection.

The procedure serves a dual purpose:

• Diagnostic purpose: The excised cone tissue is sent for histopathological analysis. This confirms the exact grade of the lesion and rules out invasive cancer, information that cannot be obtained from a biopsy alone.
• Therapeutic purpose: By removing the entire transformation zone where abnormal cells develop, conization eliminates the lesion with clean margins, achieving a cure in 90-97% of high-grade CIN cases.

The operation typically takes 20 to 30 minutes. It is performed under local or general anesthesia depending on the technique selected and clinical context.

When is cervical conization recommended?

Conization is not the first-line response to every abnormal smear. It is recommended in specific clinical scenarios where the risk of cancer progression is meaningful:

• CIN 2 or CIN 3 confirmed by colposcopy-directed biopsy, moderate-to-severe dysplasia with transformation zone involvement.
• Persistent low-grade abnormalities (CIN 1) that remain unchanged after 18-24 months of surveillance.
• Adenocarcinoma in situ (AIS) of the cervical canal.
• Unsatisfactory colposcopy: the transformation zone is not fully visible, making a complete assessment impossible.
• Suspected micro-invasive cervical cancer, requiring full histological evaluation of excision margins.

Situations where conization is postponed or avoided:

• Active pregnancy (unless absolutely urgent, management is deferred to postpartum).
• Untreated acute genital infection.
• Severe, uncontrolled coagulation disorders.

The three main techniques: LEEP, laser & cold knife

Choosing the right technique is a clinical decision made by the gynecologist, based on the size, depth, and histological type of the lesion. Each method has distinct advantages:

Most common: LEEP / LLETZ

The Loop Electrosurgical Excision Procedure (LEEP/LLETZ) uses a thin heated wire loop to remove abnormal cervical tissue with precision.

• Usually performed under local anesthesia.
• Outpatient procedure (same-day discharge).
• Short recovery time.
• Commonly used for CIN 2-3 lesions.
• Generally associated with a lower obstetric risk compared to deeper conizations.

High precision: CO₂ laser

Laser conization uses a focused CO₂ laser beam to excise abnormal tissue while minimizing thermal damage to surrounding healthy cervical structures.

• High surgical precision.
• Reduced bleeding during the procedure.
• Particularly useful for anatomically complex lesions.
• Often preferred in selected fertility-preservation cases.

Complex or suspicious lesions: Cold knife cone

Cold knife conization is the traditional surgical technique performed with a scalpel under regional or general anesthesia.

It is generally reserved for:

• Large or deep cervical lesions.
• Glandular abnormalities (AIS).
• Suspected micro-invasive cervical cancer.

Because the tissue is removed without thermal damage, this method provides the most reliable histological margins for pathology analysis.

How the procedure works: Step by step

Cervical conization is a minimally invasive gynecological procedure that is usually performed in a hospital setting and allows both treatment and precise diagnosis of cervical lesions.

At Turquie Santé partner hospitals in Turkey, the process is streamlined to reduce waiting time and ensure a safe, well-coordinated experience.

Before the procedure

A standard preoperative assessment is completed to ensure safety. At Turquie Santé partner hospitals in Turkey, this workup is typically performed on the same day or the day before surgery, eliminating the need for multiple pre-trip consultations.

1. Blood panel: Complete blood count and coagulation testing
2. Anesthesia review: Anesthesiologist consultation and allergy screening
3. Pelvic evaluation: Gynecological exam and colposcopic mapping

Pre-procedure instructions: Avoid sexual intercourse for 48 hours before the procedure. Do not use vaginal tampons, suppositories, or creams for the week prior.

During the procedure

The patient is positioned in the standard gynecological lithotomy position. After anesthesia is administered, the surgeon inserts a speculum and uses a colposcope to visualize the cervix. The cone of tissue, encompassing the entire transformation zone and endocervical canal to the required depth, is then excised. The specimen is immediately sent to pathology. No external incisions are made, and no visible scar results.

After the procedure

In most cases, patients are discharged the same day after a short observation period. Mild cramping or light bleeding may occur for a few days and is considered normal.

Final pathology results are usually available within 8 to 15 days, confirming whether all abnormal tissue has been successfully removed.

Your medical team will review the results with you and determine whether follow-up or additional treatment is needed.

Recovery timeline after cervical conization

Recovery after cervical conization is usually smooth and well tolerated. Most patients return to normal daily life within a few days, but full cervical healing takes several weeks.

1. Day 0: Discharge day: Return home the same day in most cases. Light spotting is normal and expected. Take prescribed anti-inflammatories if mild cramping occurs
2. Days 1-28: Early healing: Light pinkish discharge or spotting is common. Mild cramping may persist for a few days. Strictly avoid: sexual intercourse, internal tampons, and menstrual cups during this period.
3. Weeks 4-6: Eschar shedding: The natural cervical scab (eschar) detaches, which can cause a brief increase in discharge. Avoid prolonged baths, swimming pools, and the sea to reduce infection risk.
4. After Week 6: Full recovery: Cervical mucosa is fully restored. Normal activities, including swimming and intercourse, may resume with your doctor's clearance.

Long-term surveillance protocol

Conization removes the visible lesion, but HPV may persist in the body. A structured follow-up plan is mandatory to confirm complete remission:

• 6 months post-procedure: HPV co-test (Pap smear + HPV DNA test)
• 12 months post-procedure: Confirmatory viral clearance check
• Years 2-10: Annual surveillance in line with international gynecological oncology guidelines

Clinical efficacy: What the evidence shows

Meta-analyses published in The Lancet Oncology and Gynecologic Oncology consistently report a 90-97% rate of complete lesion clearance for CIN2/CIN3 after a single conization procedure, regardless of whether LEEP or laser is used. In the minority of recurrence cases, a second procedure achieves near-total control.

Conization and fertility: What every patient should know

This is one of the most common concerns among patients diagnosed with cervical lesions, and the reassuring answer is that fertility is rarely affected.

Does conization affect the ability to conceive?

Cervical conization does not compromise a woman's fertility. The procedure is confined to the superficial portion of the cervix and has absolutely no effect on the ovaries, the uterine cavity, or the fallopian tubes. Conception remains fully possible after recovery.

The rare exception: in cases where conization causes significant cervical canal narrowing (stenosis),a minor dilation procedure easily resolves this without permanent consequences.

Pregnancy after conization: Key considerations

While conception is unaffected, it is important to be aware of a modestly increased risk of preterm birth, particularly with cold knife or deep excisions. The key facts:

• LEEP conization carries the lowest preterm delivery risk among all techniques
• Risk of prematurity increases proportionally with the depth of cervical tissue removed
• In rare cases of wide excision, cervical cerclage (a stitch) during pregnancy may be advised
• Waiting at least 6 months after conization before attempting conception allows full cervical healing
• Inform your obstetrician of the previous conization; cervical length monitoring by ultrasound (cervicometry) may be performed during the second trimester

The vast majority of women who have had cervical conization carry pregnancies to full term without any major complications.
