Cervical adhesions do not heal on their own and need to be treated in order to recover. Cervical adhesions are usually due to postoperative complications caused by uterine surgery or cervical surgery, such as abortion operation, scraping injury, cervicitis, conical cervical excision, cervical physiotherapy, etc., which cause cervical canal narrowing or atresia and affect the discharge of uterine secretions or menstrual blood, with clinical manifestations of amenorrhea, periodic abdominal pain, reduced menstrual flow, severe pain in the lower abdomen when menstruation comes, and Prolonged menstrual cycle. If the cervical canal is completely blocked, symptoms such as fluid accumulation in the uterine cavity and absence of menstruation may cause infection in the uterine cavity and even infertility. Once cervical adhesions occur, hysteroscopic cervical dissection should be performed promptly. For shorter duration, the adhesions need to be separated with a cervical dilator to restore patency; for longer duration or tight adhesions, the adhesions need to be incised and drained of fluid or menstrual blood, and a drainage tube or birth control device placed to avoid re-adhesion. Patients with cervical adhesions must prevent infection after treatment, wear loose, cotton underwear, keep the vulva dry and clean, and do not have sex for a month.
