The incidence of uterine adhesions has increased significantly in the last 20 years, and most patients have a history of uterine clearance and induction of labor. There are 4 very important aspects in the normal pregnancy process, namely ovulation of the ovaries, patency of the fallopian tubes, tolerance of the endometrium and normal semen of the male partner. In patients with uterine adhesions, the change in the uterine environment is not conducive to embryo implantation and leads to infertility, which is also one of the main reasons for IVF failure, and can also lead to reduced menstruation or even amenorrhea. The uterus can be divided into endometrium, myometrium and plasma layer from inside to outside, and the endometrium is closely related to embryo implantation. The endometrium can be divided into basal and functional layers. In normal women, menstruation is formed due to the periodic exfoliation and bleeding of the functional layer in response to hormonal changes in the body, followed by the proliferation of cells from the basal layer to form a new functional layer again. In the process of uterus removal or induction of labor, if the surgeon is not skilled enough and damages the basal layer, or if there is residual embryonic tissue and anti-inflammatory treatment is not performed, these can easily lead to the occurrence of cavity adhesions. At present, the treatment of hysteroscopic adhesions is mainly done with the help of hysteroscopy, which has been widely used in China and is very skilled. Under the hysteroscope, we can observe the extent, scope and location of the adhesions and treat them with special instruments, such as scissors, electrodes, etc. After the adhesions are separated during surgery, different treatment methods can be chosen depending on the patient’s condition. Patients with mild adhesions are usually given an intrauterine device, intrauterine local injection of estrogen, and oral contraceptive pills for 1-3 months, followed by a review and removal of the device. Patients with more severe adhesions require intrauterine placement of a balloon urinary catheter for 5-7 days followed by IUD insertion and oral estrogen therapy for about 3 months followed by a review. The IUD and balloon urinary catheter can play a supporting and hemostatic role to prevent re-adhesion of the trauma, and estrogen can promote the growth of the endometrium, which facilitates the repair of the endometrium and prevents re-adhesion. In a large number of clinical case studies, the effectiveness of hysteroscopy for the treatment of uterine adhesions has been confirmed, with short operation time, few complications, quick postoperative recovery, less patient pain and lower cost, which can be accepted by most patients.
