Most of the hysteroscopic endometrial surgery will be performed by segmental scraping or endometrial electrosurgery. After surgery, pay attention to rest, avoid straining, abstain from sex, take a tub bath for 1 month, pay attention to keeping warm and avoid getting cold. The diet should be supplemented with high-protein food to promote the healing of the uterine wound, and spicy and stimulating food should be prohibited. If the vaginal bleeding is more than the menstrual flow, or if the bleeding does not clear for more than 2 weeks with lower abdominal pain, a follow-up examination is needed to rule out the possibility of post-surgical infection. After the surgery, it is necessary to follow up 1-2 weeks according to the doctor’s prescription to understand the pathological results before formulating the next treatment plan. Some cases of excessive endometrial hyperplasia need to be treated by adding progestin during the second half of the menstrual cycle, or by intrauterine Mannorrhea ring.
