China has a large population and a very large cesarean section population. In view of the current two-child policy, more and more families are brewing new lives and welcoming new family members, while more and more friends who have undergone cesarean delivery, who are indifferent to the knowledge of contraception, are also having unwanted pregnancies. Wang Xipeng, Department of Gynecology, Shanghai First Maternity and Child Health Hospital However, the main thing to watch out for in the early stages when women who have experienced cesarean delivery become pregnant again is scar pregnancy. What is meant by scar pregnancy, that is, the pregnancy pregnancy gestation is planted near the cesarean incision site, or completely covers the scar site. Pregnancy in this area is equivalent to ectopic pregnancy, the foreign English term, which also torments the description. What are the dangers? 1, Pregnancy at the scar site, due to the weakness of the muscular layer and the discontinuity of the meconium, is prone to haemorrhage, and in severe cases, it even penetrates the plasma membrane of the uterus and enters the abdominal cavity. here there are types I and II, type I pregnancy protrudes from the uterine cavity and type II protrudes from the plasma membrane layer of the uterus and enters the abdominal cavity. type II is more dangerous. 2, due to the neglect of ultrasound, some patients with scar pregnancy, who undergo routine abortion or medical abortion, end up causing unexpected hemorrhage, which is very sudden and tricky to handle, and serious cases have been reported of hysterectomy. 3. Some patients who experience abortion and find scar pregnancy are then given drug conservative treatment, but this repeated bleeding and mechanization process ends up forming a large hematoma in the lower part of the uterus, which is impossible to absorb, and in order to preserve the uterus, they all end up being treated surgically. The duration of the disease is very long and the pressure on the patient is very high. The main treatments available are intervention + uterus removal and chemotherapy + uterus removal. Interventional and chemotherapy, despite their inadmissibility, are both used to kill the embryo and then to perform abortion and aspiration. Both have great shortcomings: 1. Intervention is through the blood vessels of the femoral artery, upstream permanent embolization of bilateral uterine arteries, such patients, after the operation, often have very little menstruation, and further evaluation is needed for re-birth, as well as other complications may be, such as premature ovarian failure, and at the same time costly. 2. The treatment time of chemotherapy is long, and the toxic side effects of chemotherapy are self-evident, such as hair loss, bone marrow suppression and liver and kidney function damage. After performing vaginal surgery for many years, especially after carrying out more than 200 cases of transvaginal repair of uterine incisional diverticula in recent years, I We have also started to try to perform transvaginal scar gestrectomy. In the past year, the vast majority of such patients in ICH have been treated directly by me. The results have been excellent, with no complications. The advantages of transvaginal excision of scar pregnancy: 1. transvaginal surgery is the most natural and minimally invasive, with no scars on the abdomen and the best recovery; 2. transvaginal surgery can remove the most complete scar pregnancy lesions; 3. the biggest advantage is that while removing the scar pregnancy, the muscle layer of the scar site can also be repaired, so that the risk of incisional diverticulum can be prevented after surgery. 4. The complications of intervention and chemotherapy are completely avoided. This type of surgery is totally dependent on the surgeon’s solid vaginal surgical skills, and if mastered, it is undoubtedly one of the new options for patients with scarred pregnancies.
