1, if the adhesions are extensive, never ask for a heart cut and expect to get it done at once, it may be better to carry out the separation in stages. Because the speed of mucosal epithelial spreading growth is basically fixed, the figure is about 0, 5mm/day. If you separate a large area of adhesions at one time, there is little chance that the center of the endometrial defect will be covered by the proliferating endometrium and will easily re-adhere. This will cause you to have to separate again, and the more times you operate, the more damage will be done. What about staging, you can make sure that the separated part is covered by new endometrial cells, so that you can expect the endometrium at the separation to recover completely and again hysteroscopically separate the adhesions above it. This gradually makes the endometrium grow full of the uterine cavity in stages; 2. The period of adhesion formation is 7-10 days after surgery, so a simple probe separation is good at this time; 3. If there is a lot of bleeding after surgery, place a balloon catheter for 3 days. If there is a lot of bleeding, a simple probe should be placed for 3 days to prevent adhesions, and the balloon catheter should be removed before placing the IUD; 4. Infection is definitely beneficial, once the uterine cavity is infected, adhesions are more likely to occur. Please discuss and correct.
