Hysteroscopy alone is not harmful to the patient’s body. Hysteroscopy is performed under strict aseptic operation, only the hysteroscope probe is placed into the patient’s uterine cavity to observe the condition of the uterine cavity and determine the possibility of organic lesions or endometrial tumors, as well as to observe the morphology of the female uterine cavity and the patency of the bilateral fallopian tubes, etc., which is of great clinical value. The procedure is non-invasive and does not damage the uterine cavity, and the examination time is relatively short, so it does not cause any harm. Hysteroscopic surgery may cause damage to the patient’s body, which can be large or small, depending on the patient’s disease condition, the skill of the surgeon, and the length of the operation. If the operation goes well, it can have no effect on the patient, and if it does not go well, there can be serious damage to the endometrium and various dangerous situations such as perforation of the uterus, water poisoning, and water embolism.
