Tell you some diagnostic methods of ectopic pregnancy

At present, ectopic pregnancy is a disease that, depending on the location, includes tubal pregnancy, ovarian pregnancy, abdominal pregnancy, cervical pregnancy and uterine rudimentary horn pregnancy. Among ectopic pregnancies, tubal pregnancy is the most common.

Diagnosis of ectopic pregnancy:

1. Posterior fornix puncture. Because the blood in the abdominal cavity is most likely to accumulate in the rectouterine pouch, even if the amount of blood is not large, it can be sucked out through the posterior fornix puncture. Use an 18-gauge long needle to pierce the rectouterine pouch from the posterior fornix of the vagina. A positive result is obtained if dark red non-coagulated blood is drawn out, indicating the presence of blood accumulation in the abdominal cavity.

2. When using ultrasound to diagnose early tubal pregnancy, B-ultrasound images show that the uterus is enlarged, but the uterine cavity is empty. There is a low echo area next to the uterus. This image is not the acoustic feature of tubal pregnancy. The possibility of early intrauterine pregnancy with corpus luteum should be ruled out. Using ultrasound to detect the 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. It can show that one side of the uterine horn is protruding, the local muscle layer is thickened, and there is an obvious gestational sac inside.

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

4. Diagnostic curettage for endometrial pathology examination is only suitable for patients with heavy vaginal bleeding. 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, ectopic pregnancy should be considered, but it cannot be confirmed.

5. 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. A more sensitive β-hCg radioimmunoassay or monoclonal antibody enzyme-labeled method must be used to detect ectopic pregnancy.
