Abortion cannot be performed without the gestational sac reaching the uterine cavity, which requires the presence of a gestational sac in the uterine cavity. If there is no gestational sac in the uterine cavity or if a gestational sac-like echo is found in the ectopic fallopian tube, abortion cannot be performed. If the gestational sac does not reach the uterine cavity, it may be a biochemical pregnancy. A biochemical pregnancy is one in which the HCG is elevated in the blood, but no sign of a gestational sac is ever found on the ultrasound. A few days after the menstrual cycle, due to the withdrawal of hormones in the body, there is vaginal bleeding, and when the HCG is checked after the blood clears, it is almost absent or very low. Then there is ectopic pregnancy or ectopic pregnancy, where the gestational sac has colonized in the fallopian tube due to inflammation of the fallopian tube and planted on the mucosa of the fallopian tube, resulting in ectopic pregnancy, which cannot be aborted. Depending on the level of blood HCG and the size of the mass indicated by ultrasound, conservative treatment, expectant treatment, medication or surgical treatment can be done, and surgical treatment includes open surgery and laparoscopic surgery, and surgical methods include tubal preservation surgery and tubal resection.
