Tubal laparotomy is best done within 3-5 days after menstruation because the endometrium is thin and the hormone level in the body hasn’t grown yet, so pelvic operation at this time can reduce bleeding after the operation and avoid uncomfortable manifestations, and tubal surgery can be performed according to one’s own situation. However, there are some women who undergo tubal surgery, which is the opening of the fallopian tube to remove the embryo, for women with ectopic pregnancy, because there is no time limit for ectopic pregnancy, as long as the diagnosis of ectopic pregnancy and meet the indications of the surgery can be carried out pelvic operation, to avoid the risk of rupture of the fallopian tube with the passage of time, causing hemorrhage.
