如何执行测试
This procedure is done in the hospital or in a surgery center. 在手术过程中:
- You will be given general anesthesia (asleep and pain-free), or medicines to help you relax and feel sleepy.
- You will lie on a table and place your feet in stirrups to position your pelvis for exam. The health care provider will place an instrument (speculum) into your 阴道 to better see the 子宫颈.
- A small cone-shaped sample of tissue is removed from the
子宫颈 . The procedure may be performed using a wire loop heated by electrical current (LEEP procedure), 手术刀(冷刀活检), 或者是激光束. - The cervical canal above the cone biopsy may also be scraped to remove cells for evaluation. This is call an endocervical curettage (ECC).
- The sample is examined under a microscope for signs of cancer. This biopsy may also be a treatment if the provider removes all of the diseased tissue.
Most of the time, you will be able to go home the same day as the procedure.

为什么要进行测试
锥活组织检查 is done to detect 子宫颈癌 or early changes that lead to cancer. A cone biopsy is done if a test called
锥活组织检查 may also be used to treat:
- Moderate to severe types of abnormal cell changes (called CIN II or CIN III)
- 非常早期阶段
子宫颈癌 (第0或IA1阶段)
正常的结果
A normal result means there are no precancerous or cancerous cells in the 子宫颈.
异常结果意味着什么
Most often, abnormal results mean that there are precancerous or cancerous cells in the 子宫颈. These changes are called cervical intraepithelial neoplasia (CIN). The changes are divided into 3 groups:
- CIN -轻度发育不良
- CIN II -- moderate to marked dysplasia
- CIN III -- severe dysplasia to carcinoma in situ
Abnormal results may also be due to 子宫颈癌.
风险
风险 of cone biopsy include:
- 出血
- Incompetent 子宫颈 (which may lead to 早产)
- 感染
- Scarring of the 子宫颈 (which may cause painful periods, 早产, and difficulty getting pregnant)
- Damage to the bladder or rectum
锥活组织检查 may also make it hard for your provider to interpret abnormal Pap smear results in the future.
