What is the difference between aspiration and curettage?

In the life of couples, unexpected pregnancy often occurs, but they are not fully prepared. They may choose some abortion operations to end the pregnancy, and suction uterine curettage and dilatation are more common. So what are the differences between them?

Definition: Abortion is the surgical termination of pregnancy. Vacuum aspiration is suitable for those who are pregnant within 10 weeks. A suction tube can be inserted into the uterine cavity and the embryonic tissue can be sucked out with negative pressure to terminate the pregnancy. Dilation and Curettage: Dilation and Curettage is a procedure in which the endometrial tissue is scraped out and collected from the uterus.

Purpose of uterine aspiration: to terminate pregnancy. Curettage: diagnostic biopsy; treatment of irregular uterine bleeding; removal of fetal tissue (for induced abortion or treatment of incomplete spontaneous abortion);

Indications

Vascular aspiration: 1. Pregnancy is within 10 weeks and termination of pregnancy is required without contraindications. 2. Those who are not suitable to continue pregnancy due to certain diseases.

Curettage: 1. Menstrual disorders, those who need to understand the changes in the endometrium and its response to sex hormones; 2. Excessive menstrual bleeding; 3. Vaginal bleeding after sexual intercourse; 4. Infertility, those who need to understand whether ovulation occurs; 5. Endometrial polyps; 6. Uterine fibroids; 7. Early diagnosis of uterine cancer; 8. Early diagnosis of cervical cancer; 9. Endometrial hyperplasia; 10. Intrauterine contraceptive device incarceration; 11. Artificial abortion; 12. Incomplete spontaneous abortion.

harm

Aspiration uterine surgery: Short-term complications of aspiration uterine abortion include bleeding, residual uterine uterus, infection, vacuum, cervical injury, perforation, artificial abortion syndrome, embolism, etc. Long-term complications include intrauterine adhesions, secondary infertility, cervical insufficiency, increased miscarriage rate, and amenorrhea due to endometrial damage. Complications of medical abortion include residual bleeding, bleeding, prolonged bleeding, and mild prolongation of menstruation.

Curettage: The doctor cannot see inside during the curettage operation. He or she only performs the operation based on clinical experience to judge whether the scraping is thorough. If the scraping is shallow, bleeding may occur due to incomplete scraping, which may result in a second curettage. If the scraping is too deep, it will inevitably cause trauma to the endometrium due to excessive scraping and damage the function of the uterus. A single curettage, especially multiple curettages, can lead to uterine cavity adhesion and cervical adhesion, which can cause infertility. The endometrium is the implantation layer of the fertilized egg, and the result of curettage is the destruction of this functional layer. Repeated curettage will lose the loose soil suitable for seed growth, making it more difficult to get pregnant.
