Treatment of cervical erosion

Diagnosis is not difficult based on clinical manifestations, but it should be noted that cervical erosion is difficult to distinguish from cervical intraepithelial neoplasia or early cervical cancer in appearance. Routine cervical scraping and endocervical aspiration should be performed, and colposcopy and biopsy should be performed when necessary to confirm the diagnosis.

There is a clear boundary between the eroded surface of the cervix and the surrounding normal squamous epithelium. Clinically, it is often divided into three categories according to the area of ​​erosion: mild (Ⅰ°), moderate (Ⅱ°), and severe (Ⅲ°). If the erosion area accounts for 1/3 of the total area of ​​the cervix, it is mild cervical erosion. If the erosion area accounts for 1/2 of the total area of ​​the cervix, it is moderate cervical erosion. If the erosion area exceeds 1/2 of the total area of ​​the cervix, it is severe cervical erosion.

Treatment of cervical erosion

(1) Drug treatment: For patients with small erosions and shallow inflammatory infiltration, the following drug treatments can be used:

①10-20% silver nitrate: Apply topically once a week, 2-4 times as a course of treatment.

② Potassium permanganate: Apply locally after menstruation, and repeat the application once after 1 to 2 months. When using the above drugs, be careful to prevent burns to the surrounding vaginal wall, and pay attention to disinfection during use to prevent repeated infection.

(2) Physical therapy: used for cervical erosion with a large erosion area and deep inflammatory infiltration.

① Electric ironing: Use a special electric iron to burn the eroded surface tissue, causing it to necrotize and fall off, and the ironing must reach a certain depth, so that the treatment effect is good.

② Cryotherapy: Use a special rapid freezing device to freeze, necrotize, and fall off the lesion tissue on the cervical erosion surface. The commonly used cryogen is liquid nitrogen, which can reduce the temperature of the freezing head of the freezer to -196 degrees Celsius. It is placed on the surface of the cervix to freeze the eroded tissue to necrotize and fall off, and then new epithelial tissue will grow again. It can be cured in one time. Generally, there are no adverse reactions. A few patients have slight dizziness, lower abdominal pain, etc.

③ Laser treatment: Carbon dioxide laser therapy device is often used. A special laser treatment head is used to irradiate the cervical erosion tissue, which carbonizes, crusts, and falls off the erosion tissue, and then regenerates new squamous epithelium. Generally, it can be cured in one session. There is no special discomfort during the operation, and a few patients bleed when the scab falls off.

④KS instrument treatment: It is a treatment using special wavelengths of light and heat, which is painless and effective. During the treatment with the above methods, attention should be paid to the cleanliness of the vulva, and sexual intercourse, vaginal irrigation and sitting baths are prohibited. Regular check-ups should also be conducted to observe the healing of the erosion surface.

(3) Surgical treatment: For patients who are ineffective with medication and physical therapy, have deep or large cervical erosion, have cervical hypertrophy, or are suspected of having cancer, cervical cone resection or total hysterectomy may be considered.
