How is colposcopy performed?

It is best to be on an empty stomach before a colposcopy examination, so that the effect will be better. This examination method can have a clear diagnostic effect on many gynecological diseases, and the misdiagnosis rate is very low. Therefore, female friends should go to the hospital for this examination immediately when they feel that there is something wrong with their body. In addition, the patient will not feel very painful during the examination.

Electronic colposcopy is of great value in diagnosing diseases of the female lower reproductive tract, especially cervical diseases.

Colposcopy can detect cervical lesions in time, provide targeted biopsy of suspicious abnormal areas, and make a diagnosis in combination with pathological examination. This can increase the detection rate of cervical precancerous lesions and cervical cancer. In recent years, the number of early detection cases of cervical precancerous lesions and cervical cancer has continued to increase. Electronic colposcopy is an important means of diagnosing early cervical cancer and cervical precancerous lesions.

Electronic colposcopy is suitable for married or unmarried women with sexual experience, especially for those with cervical erosion, long-term unhealed cervical erosion, a history of contact bleeding, positive cervical cytology, and subclinical human papillomavirus infection. Vaginal examination is easy to perform, painless to the patient, and can be repeated. Therefore, vaginal examination is a screening method for early detection of cervical cancer.

1. Diagnosis and treatment of cervical precancerous lesions to prevent them from developing into cancer.

2. Determine the scope of suspicious lesions, guide the positioning of biopsy, and improve the positive rate of biopsy.

3. Determine the normal and abnormal squamocolumnar junction and transitional zone. Colposcopy can observe the local structure and morphology of the vulva, vagina and cervix. It is mainly suitable for abnormal cytological changes and clinically suspected cancer, such as long-term treatment of chronic cervicitis, but the therapeutic effect is poor, and it is necessary to rule out the presence of cancer or precancerous lesions. It is difficult to determine the subtle external structure of the lesion by naked eye observation and it needs to be observed under a colposcope.

4. Observation of male and female sexual diseases, dynamic observation of local changes before and after diagnosis and treatment.

5. Cervical, vaginal and vulvar intraepithelial neoplasia and cancer.

6. Before cervical cancer surgery, the scope and location of the lesion must be determined under a colposcope to guide the surgery, so as to more thoroughly remove the vagina and inquire whether there is a history of contact with ethinyl stilbestrol during the fetal period.
