In this article, we will describe what this examination is, in which cases it is prescribed, how it is performed, and how to prepare for it.
What is it?
Extended colposcopy is an advanced method for examining the cervix, vaginal walls, and the external os of the cervical canal using a special instrument—the colposcope—which provides multiple image magnification. Unlike the standard procedure, extended colposcopy additionally uses diagnostic solutions—acetic acid, Lugol's solution (the so-called Schiller's test), and, if necessary, special dyes. These substances cause characteristic tissue changes, helping the physician reveal hidden areas of epithelial abnormalities that are invisible during a routine examination.
The procedure is performed on an outpatient basis, without the need for analgesia (pain relief), lasts on average from 10 to 30 minutes, and is usually well-tolerated. The physician sequentially applies the reagents to the cervical mucosa, carefully observing its reaction under magnification. This allows for the precise delineation and characterization of the pathological focus, the identification of pre-cancerous changes, and the suspicion of malignant processes at the earliest stages. The method is characterized by high informativeness, safety, and is often included in comprehensive diagnostic protocols in gynecology.
What Does Extended Colposcopy Reveal?
This method gives the physician the opportunity to study in detail the condition of the vaginal portion of the cervix and the vaginal walls. An important advantage of the procedure is not only the visual assessment of the epithelium but also the observation of tissue reaction to special solutions, which makes the diagnosis more accurate and informative.
Extended colposcopy can be used to:
• Detect changes in the vascular pattern, including atypical vascular formations.
• Determine the degree of keratinization (or cornification) or thinning of the epithelial layer.
• Identify characteristic areas such as leukoplakia, mosaic pattern, and areas that do not stain with iodine (iodine-negative areas).
• Precisely determine the sites requiring directed biopsy.
• Differentiate physiological changes, such as ectopy (or ectropion), from pathological conditions, including dysplasia or signs of an oncological process.
• Monitor changes dynamically during follow-up examinations.
Thus, extended colposcopy significantly increases the accuracy of diagnosing cervical diseases. The method is especially valuable in cases of dubious or ambiguous cytological results, and when a lesion associated with oncogenic HPV strains is suspected.
When is Extended Colposcopy Prescribed?
The indications for this procedure cover a wide range of gynecological issues. It is prescribed for:
• Detection of atypical cells based on the PAP-test (Papanicolaou test) results or suspicion of dysplasia in cytology.
• Complaints of contact bleeding, especially after sexual intercourse or a gynecological examination.
• Detection of erosion, ectopy, or other visible changes of the cervix.
• Suspicion of HPV infection, especially when high-risk (or high-oncogenic) types of the virus are identified.
• The need to evaluate the results of treatment for dysplasia or Cervical Intraepithelial Neoplasia (CIN), as well as after surgical interventions.
• Preparation for biopsy or to clarify a preliminary diagnosis.
• Monitoring of women in the high-risk group for cervical cancer.
The risk group includes women with a family history of oncological diseases, those who started sexual activity at an early age, smokers, those with multiple births or abortions, and those using hormonal contraceptives for a long time. Extended colposcopy may also be recommended as part of screening or preventive examinations if there is the slightest suspicion of pathology.
Contraindications to the Procedure
Although extended colposcopy is considered a safe procedure, its performance is postponed or not recommended at all in several cases. Key contraindications include:
• Acute inflammatory diseases of the vagina or cervix—infection can distort the picture and intensify discomfort.
• Heavy bloody discharge, including menstruation—they obstruct tissue visualization and render the examination uninformative.
• Individual intolerance to the components of the solutions used—acetic acid, iodine, aniline dyes.
• Recent surgical or invasive interventions in the area of the cervix and vagina—cauterization, biopsy, excision, laser therapy, conization. In such cases, full tissue healing must be awaited to prevent complications.
Before prescribing the procedure, the physician always conducts a preliminary examination and takes a medical history (anamnesis) to rule out possible contraindications. This allows for choosing the optimal timing and avoiding risks associated with improper colposcopy performance.
Preparation for Extended Colposcopy
For the examination to yield the most reliable results, it is important to prepare for it correctly. Despite the simplicity of the procedure, adhering to a few recommendations can significantly increase its informativeness:
• It is advisable to abstain from sexual intercourse for 1–2 days before colposcopy, as micro-trauma to the mucosa can distort the examination data.
• The use of any vaginal preparations (suppositories, creams, gels) and douching should be excluded—they can alter the microflora and the appearance of the epithelium.
• Washing should preferably be done with plain warm water, without soap or other aggressive agents.
• The most suitable time for the procedure is the 7–10 day of the cycle, when the hormonal background is stable and the mucosa is readily accessible for visualization.
• It is important to inform the physician in advance about possible allergies to reagents (acetic acid, iodine) so that the specialist can select a safe alternative.
Adherence to these simple recommendations helps avoid false interpretations and ensures the most accurate assessment of the cervical condition.
How is Extended Colposcopy Performed?
The procedure is performed in the gynecological office and usually takes from 10 to 30 minutes. The patient is positioned in the chair, similar to a standard examination.
The stages of the examination include:
1. Insertion of the speculum, providing visual access to the cervix.
2. Examination of the mucosa under normal lighting—the physician assesses its color, relief, and the presence of visible changes.
3. Treatment of the mucosa with acetic acid solution—atypical areas turn whitish (acetowhite epithelium reaction).
4. Performing Schiller's test—the cervix is treated with Lugol's solution. Iodine stains healthy cells dark, while changed areas remain light (iodine-negative areas).
5. If necessary—the use of a green filter or aniline dyes (e.g., methylene blue) for better visualization of blood vessels and epithelial structure.
Analgesia is usually not required. Slight discomfort is possible, especially during biopsy. If there are suspicious areas, the physician may immediately take material for histology (directed biopsy). After the procedure, the woman can return to her daily activities.
Rehabilitation After the Procedure
Usually, a special recovery period is not required after colposcopy, but there are some limitations:
• Slight discharge or a feeling of mild burning is possible within the first 24 hours.
• If a biopsy was performed, it is recommended to abstain from sexual intercourse for 5–7 days to allow the mucosa to heal.
• Do not use tampons, vaginal preparations, or douching until healing is complete.
• If heavy bloody discharge, pain, fever, or an unpleasant odor appears, it is necessary to consult a gynecologist as soon as possible.
The procedure is safe, does not affect the hormonal background, fertility, or the menstrual cycle. Most women return to their usual well-being on the day of the examination.
Frequently Asked Questions
Which tests are used during extended colposcopy?
During the procedure, the physician uses special tests that help detect even minor changes in the mucosa:
• Test with Acetic Acid (3–5%)—upon application of the solution, changed cells temporarily turn white. This effect allows the physician to localize suspicious areas.
• Schiller's Test (with Lugol's Solution)—helps identify areas where glycogen is absent. Such areas do not stain, which may indicate dysplasia or other abnormalities.
• Additional methods—dyes (e.g., methylene blue) and a green filter may be used to examine vascular structures. This is particularly important when precancerous or malignant processes are suspected.
Is it possible to see cancer during colposcopy?
Colposcopy, especially the extended type, allows for the identification of signs suggestive of a possible malignant process, namely:
• Areas that do not stain with iodine.
• Atypical vascular pattern (mosaic, punctation, "tortuous" vessels).
• Ulcerations, areas with an uneven surface.
• Acetowhite epithelium with pronounced borders.
However, it is important to understand that colposcopy only provides information on visual signs. Directed biopsy and histological examination are necessary to confirm the diagnosis—only based on the tissue analysis results can a definitive diagnosis be made.
Is colposcopy painful?
No, the procedure itself is painless. During the application of the acetic acid or iodine solution, a slight stinging, burning, or cool sensation is possible—this is a normal reaction that subsides after a few seconds. If the physician performs a biopsy, a brief pricking or short-term discomfort, comparable to taking a smear, may occur. Analgesia is usually not required. After the procedure, most patients feel well and do not experience unpleasant sensations.
