Cervical adhesions occur when the mucous membrane of the cervix is mechanically damaged or irritated by inflammation, resulting in narrowing or atresia of the cervix. Once this occurs, it may cause amenorrhea, scanty menstruation, abdominal pain, and infertility. For cervical adhesions, the most common treatment is hysteroscopic separation of cervical adhesions, which is an emerging minimally invasive surgical procedure. A hysteroscope is an endoscope with a fiberoptic light source that can be used to diagnose and treat lesions in the uterine cavity. It allows the surgeon to diagnose and treat under direct vision, not only to determine the presence or absence of adhesions in the cervix, but also the degree, type, and extent of adhesions, and to provide different treatments for different types of adhesions. For membranous adhesions and fibromuscular adhesions, they can be separated directly under hysteroscopy or surgically cut out, while for more dense adhesions, they need to be separated by electrodesis under ultrasound guidance. After drainage of fluid or blood in the uterine cavity, an intrauterine device is usually placed to prevent re-adhesion, or a drainage tube is placed, and postoperative estrogen and progesterone sequential medication is applied to promote endometrial growth. In addition, antibiotic treatment is applied for those with infection. For adhesions of different nature and severity, the doctor’s treatment is different. The general principle of treatment is to separate the cervical adhesions, promote endometrial repair, restore menstruation, avoid re-adhesions, and increase the pregnancy rate.
