In the clinical diagnosis and treatment work, we often come across such patients with uterine adhesion because after the surgery, we found that the menstrual flow has decreased or amenorrhea has already been reminded by doctors that it may be uterine adhesion, but because many patients are worried that the surgery will aggravate the uterine adhesion or because of this or that factor, they have repeatedly delayed the time of doing the surgery, resulting in missing the best time to decompose the adhesion. The main symptoms of uterine adhesions are amenorrhea or oligomenorrhea after abortion or spontaneous abortion, with or without cyclic abdominal pain, which can lead to secondary infertility. Any factor that causes destruction of the uterine lining can cause uterine cavity adhesions, uterine cavity adhesions related to pregnancy accounted for about 9l%; common after abortion or spontaneous abortion scraping. As well as postpartum hemorrhage after scraping. Due to the soft wall of the pregnant uterus, it is not easy to control the depth of scraping, or excessive scratching of the uterine cavity, suction with too much negative pressure, too long. Scrape off the endometrial basal layer, resulting in postoperative uterine adhesions; suction head, spatula repeatedly in and out of the mouth of the uterus, irregular dilatation of the cervix, etc. can aggravate the damage, increasing the chance of postoperative uterine adhesions; non-pregnancy-induced uterine adhesions accounted for about 9%, such as endometrial tuberculosis, fibroid excision, diagnostic curettage, and so on. One of the symptoms of uterine adhesion is cyclic abdominal pain, especially caused by the formation of stenosis due to the adhesion of the endocervical os, which prevents the outflow of menstrual blood, resulting in menstrual blood retention in the uterine cavity or reflux to the fallopian tubes and the abdominal cavity. The pain is located in the lower abdomen and is most severe during menstruation. Secondary infertility also accounts for a significant proportion. If the adhesion is above the level of the uterine cavity’s internal orifice, then there is no abdominal pain from this adhesion. Such adhesions are more serious and the treatment is not as effective as it should be. So it is important to treat the adhesions as early as possible. Once the possibility of uterine adhesion is detected, we should do the examination of uterine adhesion as soon as possible, and if it is clear that it is uterine adhesion, we should do the hysteroscopy as soon as possible to separate the adhesion. If you suspect that you have uterine adhesions, what are the symptoms of uterine adhesions? Before the appearance of hysteroscopy, the diagnosis of uterine adhesion by tubal iodine oil imaging or ultrasound is easy to miss, and cannot indicate the toughness of adhesion and the type of adhesion, so only hysteroscopy can confirm the final diagnosis. For suspected patients with a history of scraping and decreased menstrual flow, hysteroscopy should be performed to determine not only the degree of adhesions, the type of adhesions, but also the toughness of adhesions. Patients with uterine adhesions can be seen under hysteroscopy as membranous, reticular or fibrous adhesions, peripheral adhesions with adhesion cords around the uterine cavity or peripheral scarring, narrowing of the uterine cavity in the form of a crescent or barrel, asymmetry of the uterine cavity when viewed from the inner mouth, and the uterine horns cannot be seen from one side or both sides. Hysteroscopy, which integrates diagnosis with examination and treatment, is the gold standard for diagnosing uterine adhesions. It can not only diagnose the degree of adhesion but also determine the type of adhesion. Iodine oil imaging and ultrasound are only indirect hints. Some of the more difficult gynecological diseases such as uterine adhesions can be solved visually, easily and safely by hysteroscopy. For the uterine cavity adhesion, fibromuscular adhesion can be separated under hysteroscopy or surgical clipping; while for connective tissue-like dense adhesions need to be in the ultrasound or laparoscopy under the supervision of electrocutaneous separation, after the operation, placing intrauterine device or oral estrogen to prevent re-adhesion, mild and moderate uterine adhesion treatment is more effective, and can be achieved to enable the patient to resume menstruation, to achieve the purpose of fertility. The treatment of severe uterine adhesions is less effective, especially in amenorrheic uterine adhesion patients should be intervened as soon as amenorrhea is found. Failure to do so can lead to infertility. If the severe adhesions still can not have normal menstruation after hysteroscopic surgery, then such severe uterine adhesions will only cause infertility and amenorrhea. It will not cause any other harm to the body. Because the ovarian estrogen secretion is not affected by the uterine adhesions. Therefore, amenorrhea caused by uterine adhesions will not make a person old.
