In the clinic, we often encounter many young women who are infertile and a large proportion of them suffer from cervical adhesions, a disease mainly caused by abortion. In recent years, with the opening of people’s mindset and the general postponement of the childbearing age, the number of women who are unmarried and have repeated abortions or medication abortions before having children is increasing. According to the statistics of the Ministry of Health in 2004, there are about 7 million abortions in China every year, and the ratio of abortion to live birth is 60% nationwide, that is, for every 100 babies born, 60 women of the right age have abortion. With the promotion and application of painless abortion technology, the number of painless abortions and the number of repeat abortions are increasing year by year, and the resulting incidence of post-operative uterine adhesions is also on the rise, becoming a matter of concern at present. Uterine adhesions, also known as Asherman’s syndrome, were first reported by Asherman in 1948. What are uterine adhesions? Uterine adhesions are pathological changes in the uterine cavity in which the lining of the uterine cavity or the cervical canal becomes adherent. The main cause of uterine adhesions is the damage to the basal lining of the endometrium or even to the muscular layer of the uterus during abortion or spontaneous miscarriage removal due to rough handling, excessive scraping of the uterine cavity, scraping too deeply or excessive negative pressure during suction and prolonged suction, resulting in adhesions of the endometrium or the cervical canal. In addition, the repeated entry and exit of the suction tip or scraper, as well as the use of unsmooth instruments to dilate the uterus, can also cause adhesions in the cervical canal. In general, the more frequent the abortion or curettage, the greater the chance of adhesions. Clinical manifestations of cervical adhesions The clinical manifestations of cervical adhesions are mainly amenorrhea or scanty menstruation, cyclic abdominal pain, secondary infertility, recurrent miscarriage and preterm delivery. 1. Patients with uterine adhesions almost always have amenorrhea, scanty or scanty menstruation, and more dysmenorrhea. The duration of amenorrhea may be very long, some up to 2 years or more, and the application of estrogen and progesterone cannot cause withdrawal bleeding. However, after treatment and release of the adhesions, most patients have improved menstruation. In about 25% of patients, the improvement is never seen. 2. Periodic abdominal pain occurs mainly due to adhesions in the uterine cavity, especially adhesions at the cervical opening, which form stenosis and obstruct the outflow of menstrual blood, causing menstrual blood to be retained in the uterine cavity or to flow backwards into the fallopian tubes and abdominal cavity, and also forming the uterus can form endometriosis, thus causing abdominal pain. Some of them are also accompanied by a feeling of falling at the anus and lumbago, which lasts for 2-3 days and then decreases and worsens in the next cycle. 3. After the occurrence of uterine adhesions, most of them have secondary infertility. Even if pregnancy is possible, due to the reduced volume of the uterine cavity adhesions, the fetus cannot survive in the uterine cavity until full term, so there is a possibility of miscarriage or preterm delivery. Moreover, after treatment, about half of the pregnancies are still not conceived to full term. In view of the above alarming abortion rate in China and the endless pain it causes to infertility patients and families, we need to remind young women of childbearing age to “learn to care for your uterus”.
