It is useful to preserve the fallopian tubes. When a woman has an ectopic pregnancy, surgical treatment is performed by opening the fallopian tubes, removing the embryo and then suturing the tubes. After the surgery, anti-blood and anti-infection medications are given and tubal lavage treatment is also needed so that the fallopian tubes can function normally after the tubes are open. After sexual intercourse, the egg and sperm will unite and develop into a fertilized egg, which can be transported through the fallopian tube to the uterine cavity for implantation and development. Therefore, after a woman has been treated for ectopic pregnancy, it is important to prevent inflammation of the fallopian tube, otherwise there is still a possibility of ectopic pregnancy occurring again in this tube. The fallopian tube is the place where the egg and sperm are united and can only be transported through the tube to the uterine cavity for growth and development.
