The difference between laparoscopy and hysteroscopy

Most women need to undergo hysteroscopy after suffering from gynecological diseases. Hysteroscopy is a surgical procedure in which a hysteroscope is placed into a woman's uterus. It is usually used during induced labor and abortion. When hysteroscopy is used for gynecological diseases, it can also be used for hysteroscopy. Contrast examination and hysteroscopy are both common special examination methods. So what are the differences between hysteroscopy and contrast examination?

Infertility population has high uterine cavity abnormalities

Uterine cavity examination is performed by placing a fluid tube and injecting a solution containing gentamicin into the uterine cavity to fill the uterine cavity with fluid. The morphology of the uterine cavity can then be observed under ultrasound monitoring to gain a general understanding of uterine cavity problems. During the examination, some patients may be found to have positive signs such as uterine neoplasms, less smooth endometrial morphology or uterine adhesions. After positive sonograms are screened out, patients are often advised to undergo hysteroscopy, because uterine cavity examination cannot perform diagnostic and therapeutic operations. If no obvious abnormalities are found during the uterine cavity examination, the ovulation induction cycle can be entered directly.

The uterus is the temple that carries the development of the embryo, and it is also the soil that nourishes the energy and blood needed for the development of the embryo. The morphology of the uterine cavity and the condition of the endometrium directly affect the outcome of assisted pregnancy. Hysteroscopy is the gold standard for diagnosing uterine cavity diseases. Uterine cavity abnormalities are common in infertile people, with the incidence of intrauterine abnormalities reaching 28-50%.

Which patients are suitable for hysteroscopy?

Most people often think that if no abnormalities are found during the vaginal ultrasound examination, then there is nothing wrong with the uterine cavity. Some even think that hysteroscopy is expensive and delays the time for ovulation induction.

Hysteroscopy is effective in detecting abnormal uterine cavity morphology, uterine adhesions and nonspecific endometritis. In in vitro fertilization, some patients fail to achieve pregnancy after multiple transplants of several high-quality embryos, often due to some hidden uterine cavity problems.

For this group of people, mid-luteal hysteroscopy and endometrial curettage and pathological examination are often recommended to understand the receptivity of the endometrium during the implantation window. We hope to plant the hard-earned high-quality "seeds" - embryos in the "fertile" "soil" - the endometrium, rather than various saline-alkali lands full of stones and thorns, in order to achieve a higher pregnancy rate and baby-bringing-home rate.

Therefore, hysteroscopy is recommended for the following patients:

1. Patients who have undergone endometrial polyp surgery for more than half a year;

2. Ultrasound or angiography indicates abnormal uterine cavity;

3. Patients with repeated implantation failures or multiple ectopic pregnancies in the past;

4. Patients with recurrent miscarriage;

5. Those with congenital uterine malformation;

6. Patients with cesarean section scar diverticulum; patients with abnormalities found during uterine cavity examination; patients with primary infertility for a long time.
