Cervical disease is the most common disease in women and is divided into two types: acute and chronic cervicitis. Most infections are caused by pathogens invading the cervix due to childbirth, miscarriage or surgical injury. In addition, it is also related to excessive sexual intercourse, physical or chemical stimulation, and vaginitis. Chronic cervicitis is more common clinically, mostly without the manifestation of acute inflammatory process. There is a relationship between chronic cervicitis and the development of cervical cancer, but there is no absolute relationship. According to the study, the incidence of cervical cancer with cervical erosion is 0.75%, which is higher than that of those without cervical erosion. Therefore, it is important to actively treat cervicitis to prevent the occurrence of cervical cancer. Clinical manifestations The main symptom is increased vaginal discharge. Acute cervicitis is characterized by purulent leucorrhea, accompanied by pain in the lower abdomen and lumbosacral area, or bladder irritation signs such as frequent urination, urgent urination and painful urination. Chronic cervicitis leucorrhea is milky white mucus-like, or yellowish purulent; when there is severe cervical erosion or cervical polyps, it can be bloody leucorrhea or bleeding after intercourse. When the inflammation spreads to the pelvis along the uterosacral ligament, there can be lumbosacral pain, lower abdominal cramping and dysmenorrhea, which is aggravated during defecation and sexual intercourse. In addition, the sticky and purulent leucorrhea is not conducive to the passage of sperm, which may also cause infertility. Diagnosis 1. Typical clinical manifestations. 2. Gynecological examination: acute inflammation can be seen as cervical congestion and edema, or erosion, with purulent discharge from the white cervical canal, and pain when the cervix is touched. Chronic cervicitis can be seen in the cervix with varying degrees of erosion, hypertrophy, polyps, glandular cysts, ectropion and other manifestations, or see the cervical mouth with purulent discharge, palpation of the cervix harder. In case of cervical erosion or polyp, there may be contact bleeding. 3.It is difficult to distinguish cervical erosion or polyp from early cervical cancer with the naked eye. The latter is hard, brittle and easy to bleed, so it must rely on cytological pathological examination of the cervix to find cancer cells, and colposcopy and cervical tissue biopsy if necessary. 4.Colposcopy 5.Cervical TCT 6.For heavier cases and suspected CIN, cervical biopsy is feasible Treatment (1)Physical therapy: including electric ironing, freezing, laser, infrared, etc. It is suitable for those with large erosion surface and deeper inflammation diffusion, and usually can be cured with one treatment. (2) Drug therapy: Acute cervicitis can be treated with oral broad-spectrum antibiotics, such as cephalosporin antibiotics plus methotrexate. (3) Surgical treatment: cervical polyp removal is feasible for cervical polyps, cervical glandular cysts can be punctured to release fluid; cervical old laceration and mucosal ectopia, cervical circumcision (laparotomy) is feasible, this method effectively treats cervical disease and is more widely used. Prevention and recuperation 1. Keep the vulva clean. 2. Minimize the damage to the cervix from abortion and other gynecological procedures. 3.Prohibit intercourse during menstruation.
