For teratoma of the ovary, the following precautions should be taken after laparoscopic surgery: First, attention should be paid to the healing of the abdominal incision. Generally, the abdominal incision will heal in a week or so, and local bandaging will not be needed after a week. Second, we should pay attention to the situation of menstruation. Because teratoma surgery may affect the ovarian function of the patient, if the patient has low menstrual flow or even amenorrhea after surgery, it is important to consider that the surgery may have damaged the patient’s ovaries. If the patient has low menstrual flow or even amenorrhea after the surgery, it should be considered that the surgery may have damaged the patient’s ovaries, and timely treatment is needed. Thirdly, it should be noted that there may be a small amount of vaginal bleeding. It is best not to have intercourse or take a tub bath within a month. This is because the procedure will stimulate the ovaries of the patient, resulting in abnormal vaginal bleeding due to fluctuations in the hormone levels of the patient. Patients should also be careful not to eat spicy food or seafood and other hair products. Eat more fruits and vegetables and take rest.
