The health risks of having hysteroscopy are the possible complications of hysteroscopic surgery, which are uterine perforation, damage to neighboring organs, bleeding, infection, cervical damage, adhesions, etc. 1. Uterine perforation: If the cut is too deep during hysteroscopic surgery, there is a possibility of uterine perforation. 2. Neighboring organ injury: mainly due to uterine perforation is not found in time after the uterus is perforated, electric cut to the uterus adjacent to the rectum, other intestinal tubes, bladder and other tissues. Preventive measures are timely detection of uterine perforation, and the operation should be stopped immediately when uterine perforation is found; for those who cannot exclude that the uterine perforation has already appeared in the neighboring organ injury should be actively examined, and timely detected and treated. 3. Bleeding: it is mostly due to the arterial blood vessels of the myometrium or poor uterine contraction. Preventive measures are to strengthen the uterine contraction force; electrocoagulation under the microscope with obvious bleeding, especially the arterial vessels of jet bleeding; if necessary, use Foley catheter into the uterine cavity to stop bleeding with compression. 4. Cervical injury, adhesion: hysteroscopic surgery needs to pass through the cervix, there is a certain amount of tension on the cervix, which may cause cervical injury or adhesion. Although hysteroscopic surgery has a certain risk, but if operated carefully, the general and the probability of occurrence is low.
