Ectopic pregnancy, a fertilized egg that has lodged outside the uterine cavity, is medically known as an ectopic pregnancy, most commonly a tubal pregnancy. Clinically, the best treatment plan for ectopic pregnancy is based on the patient’s condition and the presence or absence of fertility requirements. At present, its treatment is mainly divided into expectant treatment, pharmacological chemotherapy and surgical treatment. 1. Expectant treatment: suitable for patients with mild pain, little bleeding, no rupture, blood HCG less than 1000miu/ml, ectopic pregnancy mass less than 3.0cm in diameter, and with follow-up conditions. 2.Drug treatment: suitable for those with mild pain, little bleeding, no rupture, blood HCG less than 2000miu/ml, ectopic pregnancy mass diameter less than 4.0cm, methotrexate (MTX) drug treatment is commonly used clinically, through inhibiting trophoblast proliferation, destroying villi, causing embryonic necrosis and shedding, and then gradually absorbed; if the blood HCG decreases and is negative for 3 times in a row after 14 days of drug use, abdominal pain, vaginal bleeding and other symptoms are relieved or disappear. If the blood HCG decreases and is negative for three times in a row, abdominal pain, vaginal bleeding and other symptoms are relieved or disappear after 14 days of administration, it is considered effective. However, MTX may have toxic side effects and cause abnormal bone marrow hematopoietic function in serious cases. 3.Surgical treatment: According to the patient’s condition, whether he/she wants to preserve fertility and the surgical method, there are conservative and radical surgery, traditional transabdominal and contemporary laparoscopic surgery; laparoscopic surgery is the main clinical treatment method for ectopic pregnancy, which has its unique advantages compared with traditional transabdominal surgery: for example, the patient’s abdominal incision is small, about 0.5-1cm, and the number is generally 3, which can be closed without sutures, and only a The number of incisions is generally 3, and the patient can be closed without stitches, with only one trauma patch, less bleeding and more complete hemostasis during the operation, significantly less pain and faster recovery after the operation, etc. For young patients with fertility requirements, especially those who have had one side of the fallopian tube removed or diseased, conservative surgical options can be used, such as laparoscopic tubal window retrieval: 3 small incisions are made in the abdomen to enter the pelvis, the fallopian tube is incised, the embryo is removed and then sutured; if the incision is small, suturing is not necessary (<1cm); if the patient has no fertility requirements or is an emergency patient with life-threatening intra-abdominal hemorrhage, immediate radical surgery should be performed. If the patient has no fertility requirements or is a life-threatening emergency patient with intra-abdominal hemorrhage and shock, radical surgery should be performed immediately, while actively rehydrating and transfusing blood to correct shock.
