95% of ectopic pregnancies occur in the fallopian tubes. The normal fallopian tube transport of eggs mainly depends on the daily activities of oviduct smooth muscle and mucosal cell cilia. After ovulation of the ovary, the contraction strength of the fallopian tube is increased by the effect of the pregnancy hormone. The umbrella end of the ovary sucks the eggs into the tube and transfers the eggs to the junction point between the ampulla and the isthmus of the fallopian tube. If an egg encounters sperm within 24 hours of discharge, it becomes pregnant.

 

Because of various reasons, the pregnant egg is blocked in the fallopian tube, which can lead to tubal pregnancy. Pelvic inflammation and chronic salpingitis are the most common factors that interfere with the normal operation of fertilized eggs and are the leading causes of tubal pregnancy.

 

 

Chronic pelvic inflammatory disease is a common gynecological inflammation in women. It is often caused by acute pelvic inflammation that has not been completely cured or inflammation in other parts spread to the pelvic cavity. Chronic pelvic inflammation can easily cause chronic lower abdominal pain, affecting women's daily life.

 

The main pathological changes of chronic pelvic inflammation are tissue destruction, extensive adhesion, hyperplasia, and scar formation, resulting in tubal hyperplasia and thickening, tubal blockage, tubal and ovarian adhesion, and tubal and ovarian masses. If the fimbria end of the fallopian tube is closed, serous exudates will accumulate to form hydrosalpinx or salpinx pyorrhea. This series of changes in the fallopian tubes caused by chronic pelvic inflammation is the leading cause of ectopic pregnancy.

 

Whether it is mucositis or peritubal inflammation of the fallopian tube, it can lead to a narrow lumen of the fallopian tube and weak peristalsis, thus affecting the operation of the fertilized eggs, leading to the implantation of the fertilized eggs in the fallopian tube cavity and the formation of ectopic pregnancy. Therefore, pelvic inflammation can lead to ectopic pregnancy.

 

Therefore, chronic pelvic inflammation needs treatment. If the patient has an acute attack, antibiotics are required for treatment. If the patient does not have an acute attack, it is mainly treated with traditional Chinese medicine, such as Fuyan Pill. At the same time, patients should strengthen their exercise and enhance immunity. 

 

Besides, pelvic surgery is also related to ectopic pregnancy. With the increase in the number of operations, the risk of ectopic pregnancy is also significantly increased. Taking ovarian cyst resection and salpingoplasty as examples, the risk of ectopic pregnancy increased 2.9 times and 5.9 times, respectively. If you have an ectopic pregnancy, the higher the probability of another ectopic pregnancy.

 

The rate of recurrent ectopic pregnancy was also high in those who retained the fallopian tubes during the treatment of ectopic pregnancy. However, repeated ectopic pregnancy often occurs in the contralateral fallopian tubes, suggesting that there may be the same potential dysfunction in both fallopian tubes.

 

Tubal dysplasia or dysfunction can also lead to ectopic pregnancy. Some women with congenital long fallopian tubes, poor muscular development, or abnormal peristalsis of the fallopian tubes may also cause ectopic pregnancy. In addition, mental factors can cause tubal spasms and interfere with the delivery of fertilized eggs.

 

In addition, if female intrauterine contraceptives fail and oral emergency contraceptives fail, the probability of ectopic pregnancy is also greater.
