What are the methods for diagnosing ectopic pregnancy?

In life, ectopic pregnancy has affected the normal life of many patients, friends and families. It is necessary for everyone to learn more about ectopic pregnancy. Now, let the experts introduce to you what are the methods for diagnosing ectopic pregnancy. I hope it can help you understand more and better the methods for diagnosing ectopic pregnancy .

Hysteroscopy: If conditions permit and it is necessary, hysteroscopy can be used to confirm ectopic pregnancy. If the above examinations suspect multiple cysts or masses, the cost of hysteroscopy is higher for further diagnosis.

Endometrial pathological examination: Diagnostic curettage. This method of diagnosing ectopic pregnancy is only suitable for patients with heavy vaginal bleeding. The purpose is to rule out intrauterine pregnancy. The uterine cavity discharge should be routinely sent for pathological examination and slices. If villi are seen, it can be diagnosed as intrauterine pregnancy. If only decidua is seen without villi, although ectopic pregnancy should be considered, it cannot be confirmed.

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 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 when dark red, non-coagulated blood is drawn out. The result indicates that there is intra-abdominal blood accumulation in the posterior fornix of the vagina. This is a method to confirm ectopic pregnancy.

Early pregnancy test: When the embryo is alive or the trophoblast cells are viable, the pregnancy test may be positive if the syncytial cells secrete hCG. 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.

Ultrasound: In the early stage of ectopic pregnancy, ultrasound examination shows an enlarged uterus, but the uterine cavity is empty and there is a low echo area next to the uterus. This image is not the acoustic characteristic of tubal pregnancy, and the possibility of early intrauterine pregnancy with corpus luteum of pregnancy must be ruled out. Ultrasound detection of the gestational sac and fetal heart rate is very important for diagnosing ectopic pregnancy, which is also a method to confirm ectopic pregnancy.
