Due to endometrial damage caused by various reasons (abortion, infection, tuberculosis, hysterectomy for longitudinal septum and myoma, etc.), menstruation may decrease or become amenorrheic, and many people are unable to conceive again. Ultrasound examination shows that the endometrium is very thin or even defective, and some people are found to have uterine adhesions by hysteroscopy. Mild adhesions can restore fertility after separation of adhesions, but many patients do not improve significantly or even worsen after surgery. The reasons for this may be related to improper surgical techniques, surgical tools, intraoperative details and postoperative management measures. At present, many hospitals are still using electrodes to separate adhesions, especially monopolar electrodes, which will increase the damage surface and make the adhesions more serious after surgery. After years of experience, I found that the only way to prevent adhesions from reoccurring is to cut the adhesions with cold knife scissors. The balloon and amniotic membrane should be released after the surgery, and there must be good drainage, and the birth control ring should not be placed. Drugs to increase blood circulation are given after the operation. The results are really significantly better than the previous methods.
