Sterilization surgeries, such as transabdominal tubal ligation and transperitoneal laparoscopic tubal sterilization, are common, and are generally not harmful to women, but complications such as hemorrhage and hematoma, infections, and organ injuries may occur. 1. Bleeding and hematoma: There is no bleeding tendency disease per se, but external or internal bleeding, abdominal wall hematoma, broad ligament hematoma, and retroperitoneal hematoma may be caused by sterilization surgery. 2. Infection: there is no systemic or local infection before the operation, but inflammation of the abdominal wall incision, peritoneum, uterus, adnexa and pelvic cavity directly related to the sterilization operation starts to appear within two weeks after the sterilization operation, and may even develop into systemic infection. 3. Injury to organs: Sterilization surgery may cause perforation or rupture of the uterus, laceration of the cervix and vaginal vault, and may also cause injury to the adnexa, bladder, intestinal tubes and mesentery, resulting in bleeding or the need for repair or removal. If women experience the above complications after sterilization surgery, it is recommended that they consult a doctor in time to improve relevant examinations, clarify the cause of the disease, and follow the doctor’s instructions for standardized treatment, so as not to delay the condition.
