In rare cases, surgery can be avoided. Conservative-observational tactics of treatment in relation to ectopic pregnancy is used if:
• the clinical picture is erased and does not worsen;
• no signs of intra-abdominal bleeding;
• HCG level drops.
This is possible in the very early stages. In this case, the fetal egg, being in the fallopian tube, ceases to develop, and subsequently calcifies. However, such a tactic requires careful observation of the woman and the readiness to operate on her at any time if the situation changes.
In some countries, methotrexate is used to simulate this process, sometimes in combination with hormone-like substances that neutralize its toxic effect. The medicine is brought to the fallopian tube or taken orally. The drug stops the development of embryonic cells, leading to its death. The fertilized egg self-destructs, sometimes calcified. In Russia, this method is not officially used. It is believed that it is ineffective, and in the event of an error in the diagnosis and subsequent confirmation of uterine pregnancy, it leads to fetal malformations.
