The hazards of minimally invasive ligation: 1, minimally invasive need to do general anesthesia, general anesthesia will lead to anesthesia accidents and cause anesthetic allergy, resulting in anaphylaxis and endangering the life of the patient. 2, minimally invasive surgery requires the formation of artificial pneumoperitoneum, which may cause air embolism, and threaten the life of the patient. Either of these two items is very harmful. So if you want to do ligation surgery, it is better to do ordinary ligation surgery. The ligation surgery itself has a very small incision, and the time is short, very simple and easy to operate, so it is better to do the ligation surgery under local anesthesia, so that the harm will be relatively less, and will be safer. It is recommended that the ligation surgery be performed when the menstrual period is 3-7 days clean and the pelvic area is less congested, so there will be less bleeding.
