Chronic cervicitis is usually considered to be caused by the transformation of acute cervicitis into chronic after incomplete treatment, or by infection caused by childbirth, abortion or surgical injury; at this time, there is no longer a large number of pathogens multiplying in the local tissues. It usually includes cervical erosion, cervical polyps, cervical hypertrophy, cervical glandular cysts, cervical mucositis, etc. 1, cervical erosion: Cervical erosion is a form of chronic cervicitis, there are two kinds of congenital erosion and acquired erosion. Cervical erosion is pseudo-erosion, where the columnar epithelium located in the cervical canal occupies the squamous epithelium on the surface of the cervix, a histomorphological change, not the usual septic, infected or ulcerated; tends to be called cervical columnar epithelial ectoplasia or cervical columnar epithelial ectopic. Currently, cervical erosion refers only to true erosion of the epithelium due to various causes (e.g. herpes simplex virus, syphilis, and other infectious diseases). At present, there are some incorrect concepts in clinical management: ignoring the physiological nature of cervical columnar epithelial ectoplasia and detection of cervicitis pathogens, overuse of physical therapy; considering cervical erosion as chronic cervicitis, ignoring its similarity to cervical precancerous lesions, and not performing cervical cytological screening for a long time, which delays the treatment of patients. In what way is it treated? For patients with cervical columnar epithelial ectoplasia, normal cervical cytology and pathogen screening (-), regular follow-up is possible and no treatment is needed. Medications: cervical epithelium with drugs with cautery properties may be effective for mild cervical erosion and hardly help for moderate to severe erosion. Physical therapy: lasers, microwaves, hysteroscopes, etc., are definitely effective in treating moderate to severe celiac disease. For patients with fertility requirements: from the perspective of fertility alone, if the secretion is not much, it will generally not affect the sperm penetration into the uterine cavity and no treatment is needed; if the secretion is viscous and large, the relatively weak sperm will be blocked by the cervical mucus, treatment options of laser, microwave, and sea-support knife are available because the depth of the first two is about 0.4mm, which will not cause cervical scarring and does not increase the probability of cervical refractory. 2, cervical hypertrophy: there is no clear diagnostic criteria, and no treatment is needed. 3, cervical glandular cyst: It is caused by the new squamous epithelium covering the mouth of the cervical glandular duct or extending into the glandular duct, blocking the mouth of the glandular duct, which has no special clinical significance and can be followed up regularly without treatment. 4, cervical polyps: benign lesions of the cervix, treatment is preferred to surgical removal. 5, cervical mucositis: cervical mucosa edema, congestion, abnormal cervical discharge can be seen, the pathogens can be examined, antibiotic treatment is needed for the pathogens.
