How to check for cervical precancerous lesions

In life, there are many people suffering from cervical precancerous lesions. As the disease becomes more serious, the harm to the patient's body is increasing. Therefore, we need to pay attention to the inspection methods, diagnose the disease as early as possible, and treat it reasonably to avoid causing more pain. So, how to conduct scientific inspections for cervical precancerous lesions?

1. Laparoscopy

Laparoscopic examination can be used if conditions permit and when necessary.

2. Pathological examination

Diagnostic curettage is only suitable for patients with heavy vaginal bleeding to exclude intrauterine pregnancy. Uterine discharge should be routinely sent for pathological examination. If villi are seen in the slice, intrauterine pregnancy can be diagnosed.

3. Pregnancy test

When the embryo survives or the trophoblast is viable, the syncytial cells secrete hCG and the pregnancy test may be positive. Since the hCG level in patients with ectopic pregnancy is lower than that in normal pregnancy, the general hCG determination method has a low positive rate and a more sensitive β-hCG radioimmunoassay or monoclonal antibody enzyme-labeled method must be used for detection.

4. Posterior fornix puncture

Since blood in the abdominal cavity is most likely to accumulate in the rectouterine pouch, even if the amount of blood is small, it can be sucked out through posterior fornix puncture. Use an 18-gauge long needle to puncture the rectouterine pouch from the posterior fornix of the vagina, and draw out dark red non-coagulated blood as a positive result, indicating the presence of intra-abdominal blood.

5. Ultrasound diagnosis

In the early stage of tubal pregnancy, B-ultrasound imaging shows that the uterus is enlarged, but the uterine cavity is empty, and there is a low echo area next to the uterus. This image is not the acoustic feature of tubal pregnancy, and the possibility of early intrauterine pregnancy with corpus luteum should be excluded. Ultrasound detection of gestational sac and fetal heart beat is very important for diagnosing ectopic pregnancy. If the pregnancy is outside the uterus, it can be diagnosed as ectopic pregnancy; if the gestational sac is located in the uterus, ectopic pregnancy can be ruled out. B-ultrasound early diagnosis of interstitial pregnancy has important clinical significance, which can show that one side of the uterine horn is protruding, the local myometrium is thickened, and there is an obvious gestational sac inside.
