Ectopic pregnancy, also known as ectopic pregnancy, is usually treated surgically when a patient develops an ectopic pregnancy, but a few patients can also be treated conservatively. Ectopic pregnancy is a common acute abdominal condition in obstetrics and gynecology, in which the fertilized egg settles outside the uterine cavity due to disease or injury of the reproductive system. In the early stage of ectopic pregnancy, patients usually have no obvious specific symptoms. With the prolongation of pregnancy, patients may experience abdominal pain, vaginal bleeding and other symptoms, and in severe cases, hemorrhagic shock and other complications may occur. Usually, patients with ectopic pregnancy need to be treated by surgery, but a small number of patients with no contraindications to drug treatment, no rupture of tubal pregnancy, and the diameter of the gestational sac is less than 4cm can also use methotrexate to carry out conservative treatment under the guidance of the doctor.
