Ligation surgery, also known as tubal ligation, includes laparoscopic surgery as well as traditional open surgery. Laparoscopic surgery mainly involves coagulation of both fallopian tubes with bipolar electrocoagulation through the laparoscope, which makes the tubes inaccessible and prevents the sperm and egg from uniting. It is a minimally invasive surgery with little damage to the patient and quick recovery. Traditional open surgery requires a small incision of about 2cm above the pubic symphysis to ligate and suture the fallopian tubes again to prevent the egg from entering the uterus for contraceptive purposes, which is a kind of sterilization surgery. The timing of the procedure is usually 3-7 days after menstruation, and there must be no gynecological inflammation. If you want to be sterilized, you can go to the obstetrics and gynecology department of the hospital and choose the right time and method of surgery according to your specific situation. After surgery, pay attention to rest and avoid overexertion.
