What Are the Different Colposcopy Side Effects?

American True Color Digital Electronic Colposcopy is an optical-mechanical high-tech diagnostic system that combines computer technology and colposcope technology. It meets the development requirements of modern medical image digitization and networking, high-definition DSP digital camera system and unique The designed light source can obtain high-quality images. The powerful image processing software can freeze, edit, store, and print the captured images. The high-quality light source and high-magnification images enable doctors to identify extremely Tiny lesion details. Can diagnose gynecological diseases more intuitively and accurately without any trauma and side effects. It is helpful to improve the diagnosis rate of cervical cancer, and has extremely important clinical value for the diagnosis of precancerous lesions. It is suitable for the screening and diagnosis of cervical, vaginal and vulvar diseases of women.

American digital colposcopy

Colposcopy as a common clinical examination method, its main function is to enlarge the lesion to be observed 10 to 30 times, used to observe the blood vessels and epithelial changes in the lesion. Combined with vaginal exfoliated cell test, this test can provide accurate biopsy site, thereby greatly avoiding the blindness of biopsy and improving the positive rate of biopsy. This test has become a common method for gynecological cancer prevention. Due to its convenient operation, patients have no pain, no cross infection, and can provide reliable biopsy sites. They can also take photos in time to save valuable clinical data, which determines its future. It still has extremely wide application value.

Applicable disease:

1. Vaginal exfoliation cytology examination above grade 3 Pap.

2. Although the cytology test was positive, the naked eye was suspected of cancer.

3, long-term treatment of cervicitis, but the effect is not good.

4. It is difficult to determine the appearance and structure of the diseased cells with naked eyes. The lesions need to be observed under colposcopy at a magnification.

5.

1. The squamous epithelium of normal cervical vagina is smooth pink. The epithelium did not change color after applying 3% acetic acid. Positive iodine test.

2. The columnar epithelium in the cervical and vaginal part of the cervical canal is moved down to replace the squamous epithelium in the cervical and vaginal parts. It is clinically referred to as cervical erosion. The surface is fluffy and red to the naked eye. After applying 3% acetic acid, the swelling quickly became grape-like. The iodine test was negative.

3. The transformation area is the area where squamous epithelium and columnar epithelium intersect, including newly formed squamous epithelium and columnar epithelium that have not been replaced by squamous epithelium. Dendritic capillaries are seen under colposcopy; grape islands formed by metaplastic epithelium surrounding columnar epithelium; openings of glands opening in metaplastic epithelium and retention cysts (cervical gland cysts) covered by metaplasia. After 3% acetic acid application, the metaplastic epithelium was obviously compared with the columnar epithelium in the circle. After application of iodine, the color of iodine varies. Pathological examination revealed squamous metaplasia.

4. The abnormal colposcopy image iodine test is negative, including:

(1) White epithelium: white color after applying acetic acid, clear boundary, no blood vessels. Pathological examination may be metaplastic epithelium, atypical hyperplasia.

(2) White spots: white patches with rough surface and no blood vessels. Also visible without 3% acetic acid. Pathological examination is hyperkeratosis or hypokeratosis, sometimes HPV infection. There may be malignant lesions deep in or around the leukoplakia, and biopsies should be taken routinely.

(3) Dot-like structure: formerly called white spot base. After applying 3% acetic acid, it turned white, with clear borders, smooth surface and very fine red spots (spot-like capillaries). Pathological examination may have atypical hyperplasia.

(4) Mosaic: Irregular blood vessels divide the white epithelium proliferated after coating with 3% acetic acid into small blocks with clear boundaries and irregular shapes, like a pattern inlaid with thin red lines. If the surface is irregularly protruded, push the blood vessels around, suggesting that the cells are hyperproliferating, and attention should be paid to canceration. Pathological examination is often atypical hyperplasia.

(5) Irregular blood vessels: refers to the irregularity of the diameter, size, shape, branch, direction and arrangement of blood vessels, such as spiral, comma, hairpin, leaf, line, and bayberry. Pathological examinations are mostly cancerous to varying degrees.

5. The surface structure of early stage cervical cancer is unclear under strong light, showing cloudiness, brain gyrus, lard, and the surface pin is high or slightly sunken. Local hyperplasia of blood vessels, enlargement of the lumen, loss of normal vascular branching, widening of each other's distance, and special disorder of morphology, can be changed in the shape of , stick, hairpin, spiral, or pompom. After applying 3% acetic acid, the surface was glassy edema or cooked meat, often with abnormal epithelium. Iodine test negative or very light
