Xiaolan had a laparoscopic salpingo-oophorectomy due to an ectopic pregnancy, and was fortunate to be hospitalized in time, diagnosed before the tubes ruptured, and underwent minimally invasive surgery, and was able to move and eat normally the day after the surgery, and was soon discharged. Before she was discharged from the hospital, the doctor specially told her about the postoperative precautions and instructed her to check that the other fallopian tube was clear before she could get pregnant. Lan has had 1 abortion before and has not yet given birth, so she is especially worried about having another ectopic pregnancy in the future. How to avoid it? In a normal pregnancy, sperm and egg combine to form a fertilized egg at the junction of the juxtapical abdomen and isthmus of the fallopian tube. 30 hours after fertilization, the fertilized egg moves towards the uterine cavity with the help of peristaltic movement of the fallopian tube and the push of the epithelial cilia of the fallopian tube. Finally, the fertilized egg enters the uterine cavity at early blastocyst on day 4. If it does not enter the uterine cavity by the late blastocyst, an ectopic pregnancy occurs. We call ectopic pregnancy, or ectopic pregnancy, when the fertilized egg is deposited outside the uterine cavity. What are the causes of ectopic pregnancy? 1, chronic pelvic inflammatory disease, including tubal inflammation Tubal inflammation is the main cause of ectopic pregnancy. Tubal inflammation can make the mucosal folds of the fallopian tube adherent, the lumen narrow, and the cilia are damaged; or the fallopian tube is twisted due to the adhesion of inflammation and surrounding tissues, and the peristaltic movement is weakened, which affects the operation of the fertilized egg. If there is no effective contraception, repeated abortions, premature sex after abortion, no proper rest, and decreased resistance, it is easy to cause tubal inflammation. The more abortions, the greater the chance of ectopic pregnancy. Therefore, women of childbearing age should know how to use contraception, pay attention to personal hygiene, protect themselves and eliminate unclean sex. 2, history of tubal pregnancy or surgical history Women who have had a history of ectopic pregnancy, regardless of whether the previous ectopic pregnancy was treated conservatively or surgically, the chances of recurrence of ectopic pregnancy can be up to 10%. And some people have done bilateral tubal ligation, the incidence of ectopic pregnancy is still 10% to 20%. Even in the clinical encounter with the same person occurred three times the phenomenon of ectopic pregnancy, the cause may be due to tubal fistula or recanalization. If you do not want to have children, you must do a good job of contraception, and ready to get pregnant women should do a hysterosalpingogram to check whether the fallopian tube is open. 3, placed intrauterine device (IUD) contraceptive failure In the placed intrauterine device, about 3% of women will get pregnant, therefore, even with a birth control ring, if there are symptoms such as irregular vaginal bleeding, abdominal pain, etc., we should also consider ectopic pregnancy. If there is diarrhea, acute and severe sensation, anal distension may be the rupture of ectopic pregnancy, due to intra-abdominal hemorrhage stimulate the intestinal tract, resulting in accelerated intestinal peristalsis diarrhea, internal bleeding accumulated in the uterorectal fossa, resulting in stool sensation, the result is to go to the toilet when fainted. 4, the failure of oral contraceptives Take emergency contraceptive pills, contraceptive success rate of about 80%, so when there is irregular menstruation, menstrual dribbling with abdominal pain, we must be vigilant about the occurrence of ectopic pregnancy. 5, tubal dysplasia or abnormal function of the fallopian tube is too long, lack of mucosal cilia, fallopian tube diverticulum, etc., may cause tubal pregnancy. In addition, insufficient functions such as peristalsis and cilia activity of fallopian tube will also affect the normal operation of fertilized egg. Even mental factors such as excessive stress and tension can affect and interfere with the normal operation of the fertilized egg. Therefore, relax and let nature take its course. It is often reported that after several failed IVF attempts due to tubal impassability, natural conception was achieved after giving up the treatment, which shows the importance of mental factors. 6, assisted reproductive technology and the probability of ectopic pregnancy in normal pregnancy, IVF can occur ectopic pregnancy, the incidence of which is 2.8%. The fertilized egg is placed in the uterine cavity on the 3rd day, so it will still be traveling before it will be implanted. If planting two embryos, there will be an intrauterine pregnancy and an ectopic pregnancy, you can surgically remove the fallopian tube on one side of the pregnancy, retaining the embryo in the uterus to continue the pregnancy. 7, pregnant egg wandering Under normal circumstances, one side of the ovary ovulation, fertilization in the same side of the fallopian tube into the uterine cavity. But in some abnormal cases, the fertilized egg will enter the uterine cavity or abdominal cavity to move to the opposite side of the fallopian tube, this is the pregnancy egg wandering. 8, uterine fibroids, ovarian cysts and tubal endometriosis and other diseases These diseases may compress the fallopian tubes, affecting the smoothness of the tubal lumen, peristaltic restriction, thus increasing the risk of ectopic pregnancy. In conclusion, women who are sexually active should remember to take safe and effective contraceptive measures, eliminate impure sex, have fewer or no abortions, and treat gynecological diseases such as pelvic inflammatory disease in a timely manner. Active anti-inflammation after ectopic pregnancy surgery can effectively prevent ectopic pregnancy. For those who have pelvic inflammatory disease, infertility, IUD or have suffered from ectopic pregnancy, pay close attention once the menopause, and consult a doctor as soon as possible to confirm the diagnosis. If abdominal pain, diarrhea, toilet shock and other symptoms, we must be alert to ectopic pregnancy, timely hospital treatment.
