Transitional disease

Introduction The prone site of cervical lesions is the transition zone between the original squamous epithelium-columnar epithelial junction and the existing squamous epithelium-columnar epithelial junction. Because the cervix surface covered with stratified squamous epithelium defense ability is better, and the cervical canal covered with single-layer columnar epithelium defense ability is poor, easy to be attacked by foreign pathogens, is the weakest link. When the process of cervical epithelial metaplasia is active, some foreign pathogens are stimulated, or the transition zone is repeatedly changed, the immature cells or the proliferating squamous epithelium in the transition zone may develop toward cervical lesions. Therefore, the cervical canal is the source of cervical lesions, and the use of cervical canal is the key to completely cure cervical erosion.

Cause

The cause of transitional lesions:

1. After childbirth or abortion, abortion, curettage and other gynecological operations, can cause different degrees of cervical laceration, reduce the immunity of the local tissue of the cervix, open the door to the pathogen, causing cervical erosion.

2. Inflammation occurs due to the invasion of bacteria, pathogens, and viruses, and local secretions increase. Cervical erosion is caused by long-term immersion of the cervix in inflammatory secretions.

3. Injury by chemical substances, such as the use of strong acid, strong alkaline drugs, or corrosive drugs for vaginal washing, or vaginal medication, damage to the cervical mucosa, so that the vaginal pH changes, destroying the female self-purification, thus giving Cervical erosion provides a "hotbed".

Examination and diagnosis of transitional lesions:

A large number of clinical observations found that the prone site of cervical lesions is the transition zone between the squamous epithelium-columnar epithelial junction. Due to the repeated changes of the transition zone, the immune system recognition reaction ability of the cervical transformation zone is weakened, becoming a weak link and easily infected by foreign pathogens and viruses. Therefore, the cervix and transition zone are the source of cervical lesions and are the key parts for curing cervical lesions.

Cervical cytology. First, the doctor will ask the patient's symptoms and menstrual conditions, and conduct a gynecological examination, visual observation of the cervix, including cervical erosion, sputum, etc., then cervical cytology, scraping some exfoliated cells on the cervix , observed under a microscope. The most commonly used is the Pap smear method. This cytology report is divided into five levels: Pap 1 is normal, Pap 2 is inflammation, Pap 3 is suspicious, Pap 4 is highly suspicious. Cancer, Pap 5 is cancer.

Colposcopy. If the cytology results are abnormal, the doctor also recommends a colposcopy, which can magnify the surface of the cervix several times. After applying 3% acetic acid solution on the surface of the cervix, the changes of color and blood vessels of the cervical epithelium were observed, and it was preliminarily determined whether there were suspicious lesions in the cervix. Because of the lesion, the epithelium will show varying degrees of whiteness.

Cervical tissue biopsy. Finally, if there is any doubt about the colposcopy, the doctor will take a small biopsy of the cervical tissue under the colposcopy, and the biopsy results will become the final conclusion of the cervical lesion.

Through these examination methods, doctors can determine whether there is any disease or disease in the cervix and give corresponding treatment measures.

Differential diagnosis

Symptoms of transitional lesions that are confusing:

The diagnosis of cervical erosion is not difficult, but the key is to distinguish from cervical precancerous lesions and cervical cancer, because cervical precancerous lesions and cervical cancer can also be manifested as cervical erosion. Cervical precancerous lesions are a curable disease. It takes about 10 years for precancerous lesions to develop into cervical cancer. Therefore, the diagnosis and treatment of cervical erosion is of great significance for the prevention of cervical cancer.
