What tests are necessary for ectopic pregnancy?

Due to the gradual increase in the number of patients with ectopic pregnancy, gynecological experts have paid great attention to it. Data show that most patients with ectopic pregnancy have fallopian tube inflammation, which leads to fallopian tube blockage and ectopic pregnancy. Therefore, women should have a certain knowledge of ectopic pregnancy. The following introduces the necessary examinations for ectopic pregnancy.

What are the necessary tests for ectopic pregnancy? Experts introduce the following content to you:

1. Ultrasound diagnosis: In early 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 ruled out.

Ultrasound detection of gestational sac and fetal heartbeat 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 inside the uterus, ectopic pregnancy can be ruled out. B-ultrasound has important clinical significance for early diagnosis of interstitial pregnancy, which can show protrusion of one uterine horn, local thickening of the muscle layer, and obvious gestational sac inside.

2. Pregnancy test: When the embryo survives or the trophoblast cells are 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.

3. Posterior fornix puncture: Posterior fornix puncture is widely used to assist in the diagnosis of ectopic pregnancy. Blood can often be drawn out and placed without coagulation, and there are small clots in it. If no liquid is drawn out, the diagnosis of ectopic pregnancy cannot be ruled out.

4. Diagnostic curettage: When ectopic pregnancy cannot be ruled out, diagnostic curettage can be performed to obtain the endometrium for pathological examination. However, the endometrial changes in ectopic pregnancy are not characteristic and can be manifested as decidual tissue, highly secretory phase with or without AS reaction, secretory phase and proliferative phase.

5. Endometrial pathological examination: Diagnostic curettage is only suitable for patients with heavy vaginal bleeding, and the purpose is 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. If only decidua is seen without villi, although ectopic pregnancy should be considered, it cannot be confirmed.

Patients with ectopic pregnancy should pay attention to diet and nutrition, ensure protein intake, avoid heavy physical labor, and try to reduce abdominal pressure. For patients who have given birth, if B-ultrasound shows that the mass disappears, sexual intercourse can be performed after the follow-up. Pay attention to menstrual hygiene and prevent infection.
