Cleansing and abortion (mostly referred to as abortion surgery) are both uterine operations that can cause some damage to the woman, but it is impossible to tell which one is less harmful. Cleansing of the uterus is the most common method of early abortion, in which the cervix is dilated to a sufficient size and then a curette is inserted into the uterine cavity to scrape off the embryo. Abortion procedures are surgical terminations of pregnancy, including negative pressure suction and forceps. The uterine operation and perioperative complications of both are basically similar, only the adaptive population is different, both will cause harm to women, but the size of the harm can not be compared. The ultrasound needs to be rechecked after abortion surgery, and if there is a large residue in the ultrasound, you need to choose the purging surgery. It is recommended that patients go to a regular hospital, according to the individual situation, choose the appropriate operation.
