Low-grade squamous intraepithelial lesions are often precancerous lesions that occur in the cervix, mostly caused by pathogens, cervical injury, etc. Some patients have no symptoms; others may have increased leucorrhea, watery, with or without odor, contact vaginal bleeding after intercourse, cervical erosion and urinary tract infection during examination. Generally, the development of the disease can be controlled through effective treatment and is not serious; however, if patients do not receive timely intervention, it may develop into pelvic inflammatory disease, cervical polyps and chronic cervical canal mucositis, which may develop into cervical cancer, which is more serious at this time. Therefore, once diagnosed, timely treatment is required under the guidance of doctors. Common treatment methods include: 1. Drug therapy: For low-grade squamous intraepithelial lesions caused by various pathogens, antibiotics or antiviral drugs are commonly used. Antibiotics have certain anti-inflammatory and anti-infective effects, and with the use of antiviral drugs can help kill the virus. If the pathogenic microorganism is not detected, you can consider the temporary use of spectral antibiotic treatment, if the drug sensitivity test has detected the pathogenic microorganism can take sensitive antibiotic treatment; 2, physical therapy: for the inflammatory infiltrative degree of patients can take physical therapy, common such as infrared therapy, liquid nitrogen cryotherapy, electrocautery, etc., less traumatic to the body, better prognosis, but not necessarily applicable to all patients, some patients may affect the pregnancy after treatment. Some patients may affect pregnancy after treatment, it is recommended to choose the treatment under the guidance of doctors; 3, surgical treatment: low-grade squamous intraepithelial lesions generally do not require surgical treatment, if the lesion develops into high-grade squamous intraepithelial lesions, surgical treatment is required, clinical common cervical circumferential electrosurgery, cervical conical resection, etc., can help improve the symptoms. However, care needs to be taken to check whether cervical cancer has occurred before surgery; 4. Chemotherapy: usually for those who need surgery, if the lesion is malignant, chemotherapy drugs, such as cisplatin plus fluorouracil, need to be selected according to the patient’s specific condition, the combination of which can help reduce the disease recurrence rate and prolong the patient’s survival time. In addition, patients still need to be reviewed regularly after symptoms improve to avoid recurrence.
