Can cervical erosion be seen with color Doppler ultrasound?

Cervical erosion is a disease that is extremely harmful to the female body. Patients with severe cervical erosion may even become infertile. There are many causes of cervical erosion, but they will eventually turn into cervicitis and then develop into cervical erosion. The early symptoms of cervical erosion are not very obvious, and many patients discover that they have cervical erosion through medical examinations. So, can cervical erosion be detected with color ultrasound?

Can cervical erosion be detected by color ultrasound? Cervical erosion is a common gynecological disease. The causes of the disease include mechanical stimulation or injury, such as sexual intercourse, miscarriage and delivery lacerations, and bacterial invasion that cause cervicitis. When suffering from mild cervical erosion, patients generally have no obvious symptoms, and may only have a slight increase in leucorrhea, which is often easily overlooked. Many patients' cervical erosion is discovered during the general survey or when they seek medical treatment for other gynecological diseases. It can only be seen during a gynecological examination and cannot be seen with the naked eye.

In addition, cervical erosion needs to be confirmed by colposcopy to determine whether it is infected. Color Doppler ultrasound cannot show cervical erosion. Colposcopy uses a colposcope to magnify the cervix 10-40 times under a strong light source for direct observation in order to detect smaller lesions that are invisible to the naked eye, and to determine the extent of cervical erosion.

The most obvious symptom of patients with moderate and severe cervical erosion is increased vaginal discharge, which is yellow and sticky, or contains blood. A small number of patients may experience bleeding after sexual intercourse. Inflammatory leucorrhea can cause long-term irritation to the vulva and may also cause vulvar pruritus. In addition, since the cervical lymphatic system is directly connected to the paracervical connective tissue, inflammation can spread to the pelvic cavity through the lymphatic circulation, leading to pelvic connective tissue inflammation, lumbar pain, lower abdominal distension and other symptoms. In a small number of patients, infertility may also be caused by cervical erosion.

Physical therapy is a better treatment for moderate and severe cervical erosion, such as laser, microwave, Bom light, red light, LEEP knife, etc.

What are the symptoms of cervical erosion? The classification of cervical erosion varies according to different situations. Generally, there are the following classification methods:

1. According to the different degrees of lesions, cervical erosion is divided into three types: mild, moderate and severe.

Mild: The erosion area is less than 1/3 of the entire cervical area; patients generally do not have any discomfort symptoms, and may only have increased vaginal discharge, which can be easily overlooked.

Moderate: The area of ​​erosion accounts for 1/3-2/3 of the entire cervical area; the main symptom is increased vaginal secretions, which are milky white mucus or light yellow purulent fluid. When accompanied by cervical polyps, there is a high risk of bloody leucorrhea or bleeding after sexual intercourse.

Severe: The erosion area reaches more than 2/3 of the entire cervical area. It causes pain in the lower abdomen or lumbosacral area, accompanied by a feeling of falling. When the inflammation is severe, it can spread along the uterosacral ligament and cardinal ligament and cause pelvic connective tissue inflammation.

2. According to the different pathological processes, cervical erosion is divided into the following two types.

Pseudoerosion: Due to the stimulation of high estrogen in the bodies of young girls and unmarried women, the columnar epithelium of the cervical canal moves outward, and the cervix appears red and granular, similar to erosion, but there is no obvious inflammation. .

True erosion: Because the surface of the cervix is ​​often covered with a lot of mucus or purulent secretions, these secretions have long-term irritation and soaking of the squamous epithelium around the external os of the cervix. Coupled with the inflammatory infiltration of the deep tissues of the cervix, the squamous epithelium covering the surface of the cervix loses its vitality and falls off, forming ulcers. This is true erosion.

3. According to the manifestations of cervical erosion, cervical erosion can be divided into three types:

Simple cervical erosion: more common in the early stage of inflammation, the erosion surface is covered by a single layer of columnar epithelium, and the epidermis is relatively flat and smooth;

Granular cervical erosion: The inflammation continues, causing excessive proliferation of the cervical epithelium, and the erosion surface is uneven and granular in appearance.

Papillary cervical erosion: If the glandular epithelium and stroma proliferate significantly, the unevenness becomes more obvious and becomes papillary-shaped, which is called papillary erosion.

4. According to the cause, cervical erosion can be divided into two types: specific and non-specific.

Specific: refers to infection caused by pathogens. Neisseria gonorrhoeae and Chlamydia trachomatis are the most common pathogens of cervical infection.

Nonspecific: Most are caused by an imbalance in estrogen secretion. For example, there are many unmarried and childless people.

5. Excluding mechanical damage, infection and other causes, it is divided into congenital erosion and acquired erosion.

Congenital erosion: In the late pregnancy, the columnar epithelium is affected by the maternal estrogen, and the columnar epithelium of the cervical mucosa proliferates and begins to grow outward from the cervical os and beyond the external os of the cervix. Therefore, about 1/3 of the cervix of newborn girls has an appearance similar to cervical erosion in adults. Since there are no factors such as laceration and infection that can cause cervical erosion at this time, this type of erosion is called congenital erosion. After birth, the influence of estrogen from the mother gradually subsides, and this erosion in newborn girls also subsides on its own.

Acquired erosion: Acquired erosion is in contrast to congenital erosion. It often occurs in women of childbearing age with strong ovarian function. The columnar epithelium of the cervical canal is overproliferated due to the influence of estrogen produced by the ovaries, exceeding the external os of the cervix, causing the external os of the cervix to become eroded.
