Celiac disease used to be a disease that plagued many women, and when they went for a physical examination, almost nine times out of ten, they would be diagnosed with celiac disease. Prior to 2008, Celiac Disease was treated as a standard disease in Obstetrics and Gynecology, and its clinical manifestations, diagnosis, and treatment were even discussed. In 2008, the 7th edition of the textbook “Obstetrics and Gynecology” abolished the name “celiac disease” and replaced it with the physiological phenomenon “cervical columnar epithelial ectasia”. Some cervical erosion is actually a misperception of a normal manifestation of the cervix in the past. Simple cervical erosion is physiological, that is, physiological cervical columnar epithelial ectasia, mostly seen in adolescence, reproductive age estrogen secretion, oral contraceptives or pregnancy. However, pathologic cervical erosion exists. Inflammatory celiac disease is mostly chronic inflammation formed by untreated or incomplete treatment of acute cervicitis. Celiac disease is typed differently according to different conditions. Generally there are the following typing methods: 1, according to the different degrees of its lesions, cervical erosion is divided into light, medium and heavy types. Mild: the area of erosion is less than 1/3 of the entire cervix; patients usually do not have any uncomfortable symptoms, may only have increased leukorrhea, which can be easily ignored. Moderate: the erosion area accounts for 1/3-2/3 of the entire cervix; the main symptom is the increase of vaginal discharge, milky white mucus, or yellowish purulent fluid. When accompanied by cervical polyps, it is easy to have bloody leukorrhea or bleeding after sexual intercourse. Severe: the erosion area reaches more than 2/3 of the whole cervix area. It causes pain in the lower abdomen or lumbosacral area with a falling sensation. When the inflammation is heavy, it can spread along the uterosacral ligament and the main ligament and lead to pelvic connective tissue inflammation. 2.According to the difference of its lesion process, cervical erosion is divided into the following 2 types. Pseudo erosion: young girls and unmarried women due to the body of higher estrogen stimulation, so that the cervical tube columnar epithelium outside, the appearance of the cervix is visible in the red, fine granular, similar to the erosion, but there is no obvious inflammation. True celiac disease: because the surface of the cervix is often covered with more mucus or purulent secretions, these secretions for a long time to stimulate and impregnate the squamous epithelium around the outer mouth of the cervix, coupled with the inflammatory infiltration of the cervix’s deeper tissues, the squamous epithelium covering the surface of the cervix loses its vitality and sloughs off, forming an ulcer, which is a true celiac disease. 3, according to the performance of the cervical erosion can be divided into three types: simple cervical erosion: mostly in the early stage of inflammation, the surface of the erosion is covered by a single layer of columnar epithelium, the epidermis is relatively flat and smooth; granular cervical erosion: inflammation continues to exist, so that the cervical epithelium is overgrown, the surface of the erosion is uneven, the appearance of the granular. Papillary cervical erosion: if the glandular epithelium and mesenchymal hyperplasia is significant, the unevenness is more obvious, and the appearance is papillary, that is, papillary erosion. 4, according to the etiology of cervical erosion can be divided into two specific and non-specific. Specific: It is caused by bacterial infection. Gonococcus and Chlamydia trachomatis are the most common pathogens of cervical infection. Non-specific: most are caused by an imbalance in estrogen production. For example, many unmarried and childless people. 5, excluding mechanical injury, infection and other causes, is divided into congenital celiac disease and acquired celiac disease. Congenital celiac disease: in late pregnancy, columnar epithelium by maternal estrogen, cervical mucosal columnar epithelial hyperplasia, began to grow to the outside of the cervical opening, and beyond the cervical opening, so in the newborn baby girl about 1/3 of the cervix appearance similar to the adult cervical celiac disease. Since the factors that form cervical erosion, such as laceration and infection, do not exist at this time, this erosion is called congenital erosion. After birth, the effect of estrogen from the mother gradually subsides, and this type of celiac disease in newborn girls also subsides on its own. Acquired celiac disease: Acquired celiac disease is the opposite of congenital celiac disease, which mostly occurs in women of childbearing age with strong ovarian function. The columnar epithelium of the cervical canal is affected by estrogen produced by the ovaries and becomes overgrown, exceeding the outer cervical opening, thus making the outer cervical opening appear as celiac disease.
