Uterine adhesions refer to traumatic damage to the basal layer of the endometrium due to various causes such as curettage and infection, which in turn causes endometrial fibrosis and mutual adhesion of the muscle wall, with clinical manifestations such as abdominal pain, menorrhagia, amenorrhea, infertility or habitual miscarriage. 1. The common causes are infection and history of uterine and cervical surgeries (including abortion, clearing the uterus after failed medical abortion, spontaneous abortion, induction of labor, gravidity, full-term delivery and cesarean section, diagnostic scraping for abnormal uterine bleeding, transcervical endometrial removal for functional bleeding, laser surgery for cervical erosion, cervical myomectomy, etc.). Previously, blinded methods (such as dilation rods) were used to separate uterine adhesions with poor results. Transcervical hysterectomy is a targeted separation or removal of cervical adhesions under direct vision and is now the standard method of treatment for cervical adhesions. The separation is preceded by hysteroscopic clarification of the diagnosis and the use of estrogen to promote endometrial growth. 2. Uterine adhesions often need to be differentiated from various central, ovarian, and uterine factors leading to amenorrhea or reduced menstrual flow, such as hyperprolactinemia or pituitary tumors, polycystic ovary syndrome, etc. Preoperative hysteroscopy is recommended. For infertile patients, the possibility of infertility due to other factors should be explained preoperatively. 3. Surgical method: The cervical dilatation rod is routinely placed in the evening before surgery to soften and dilate the cervix. 400 μg of misoprostol is placed in the posterior vaginal vault if it is difficult to place the cervical dilatation rod due to hardness, atrophy or adhesion of the cervix. Continuous epidural anesthesia is used to keep the patient awake. The dilation pressure is set at 100 mmHg and the flow rate is 300-400 ml/min. The needle electrode is used to cut the cervical and uterine adhesions and open the uterine cavity. The pelvic abnormalities detected by laparoscopic monitoring were also treated accordingly (e.g. ovarian cyst debridement, pelvic adhesions release, etc.), and the morphology of the uterine cavity was basically normalized after the operation. For those who visit the clinic for infertility (or those who have fertility requirements), the second hysteroscopy and removal of the IUD will be performed after 2 to 3 months of artificial cycles, and pregnancy will be carried out under the guidance of the doctor. 4. Artificial cycles must be performed before and after surgery to promote endometrial thickening and repair treatment.
