What does vaginal inversion examination do?

Modern women are not only concerned about their faces when it comes to taking care of their bodies, but also the skin on their bodies, hands, feet and visible places. Of course, they also pay attention to their private parts. You should know that there have been a lot of news about cervical and uterine cancer in recent years. Therefore, from the perspective of being responsible for yourself, it is very necessary to have regular physical examinations. Colposcopy is to check the vulva, vagina, cervix, pelvic cavity and other places. Let's learn about what colposcopy is?

Vaginoscopy is a method of directly observing epithelial lesions of the vagina and cervix through a colposcope under strong light, with magnification of 6 to 20 times. This allows observation of smaller lesions of the vagina and cervix that are not visible to the naked eye, and localized biopsy of suspicious areas to improve the diagnosis rate.

Indications:

1. Those with Pap test grade II or above.

2. Those with suspected cervical malignancy by naked eye.

3. There is contact bleeding, but no obvious lesions in the cervix can be observed with the naked eye.

4. Those with vulvar or vaginal lesions.

5. Those whose lesion extent is determined before cervical conization.

Check steps

1. After the patient has emptied his bladder, he takes the lithotomy position and uses a vaginal speculum to expose the cervical vagina.

2. Use a cotton ball to gently wipe away cervical secretions and mucus.

3. Observe the shape, size, color, spots and growths of the cervix with the naked eye.

4. Turn on the lighting switch, adjust the objective lens to the same level as the examined part, adjust the distance of the objective lens, generally about 20 cm away from the cervix, and adjust the focal length of the objective lens until the image is clear. Use a 10x low-power microscope to roughly observe the shape, color, and blood vessels of the cervix under white light, and then use a high-power microscope to identify cervical lesions.

5. Use a cotton ball dipped in 3% to 5% acetic acid to rub the surface of the cervix. Under the action of acetic acid, the columnar epithelium swells and becomes slightly white and grape-like, while the squamous epithelium becomes slightly white without any grape-like changes. This can be used to distinguish between the squamous epithelium and the columnar epithelium. After 1 to 2 minutes, the color change will fully appear, and the suspicious lesion area should be carefully observed. If long-term observation is required, 3% to 5% acetic acid solution should be applied repeatedly every 3 to 5 minutes. In order to clearly observe the changes in blood vessel morphology, green filter lenses can be used for inspection. After the acetic acid test, the surface of the cervix is ​​smeared with compound iodine solution. The primitive squamous epithelium is stained dark brown, the columnar epithelium is not stained, and the metaplastic squamous epithelium shows different shades of staining depending on the degree of maturity of the metaplasia. The location and range of the lesion can be determined based on this. The negative area of ​​iodine test (unstained area) is the suspected lesion site. A biopsy is taken from the negative area and sent for pathological examination.
