[Therapeutic management of tubal ectopic pregnancies: Clinical practice guidelines of CNGOF and SCGP].

Ectopic Pregnancy is defined as the presence of a pregnancy or pregnancy residue outside the uterine cavity, with a prevalence of approximately 2%. Tubal ectopic pregnancy is defined as the presence of a pregnancy or pregnancy residue in the extra-myometrial portion of the fallopian tube (isthmus, ampulla, or fimbriae), and accounts for 96 to 99% of ectopic pregnancy locations. Management of tubal ectopic pregnancy should depend on both its activity and whether it is symptomatic or not. Regarding emergency management of tubal ectopic pregnancy, it is recommended not to consider expectant management for patients with symptomatic tubal ectopic pregnancy, nor for patients with active tubal ectopic pregnancy (Strong recommendation, low quality of evidence). It is recommended to offer expectant management as an alternative to medical treatment with MTX (methotrexate) for patients with non-active and asymptomatic tubal ectopic pregnancy (Strong recommendation, low quality of evidence). It is recommended to offer expectant management as an alternative to surgical treatment for patients with non-active and asymptomatic tubal ectopic pregnancy (Strong recommendation, very low quality of evidence). In cases of expectant management of tubal ectopic pregnancy, it is strongly recommended to systematically re-evaluate the patient clinically and biologically at 48hours (Strong recommendation, low quality of evidence). If hCG levels decrease by more than 15% at 48hours, it is recommended to continue monitoring weekly until negativity, provided there are no signs of symptomatic tubal ectopic pregnancy (Strong recommendation, very low quality of evidence). If an expectant approach is chosen, and there is an increase in hCG levels of more than 15% at 48hours or the tubal ectopic pregnancy becomes symptomatic, it is recommended to discontinue expectant management (Strong recommendation, low quality of evidence). Regarding medical treatment of tubal ectopic pregnancy, it is recommended not to favor a multi-dose protocol over a single-dose protocol to increase the success rate of MTX treatment (Strong recommendation, moderate quality of evidence). It is recommended to prefer the single-dose MTX protocol over the multi-dose protocol to limit the risk of adverse effects (Strong recommendation, high quality of evidence). It is also recommended not to systematically combine mifepristone treatment with an MTX injection to improve the efficacy of medical treatment for tubal ectopic pregnancy (Strong recommendation, high quality of evidence). Regarding surgical management, in a patient with tubal ectopic pregnancy, it is recommended to perform either salpingotomy or salpingectomy with regard to fertility (Strong recommendation, high quality of evidence). It is recommended not to perform tubal expression in order to reduce morbidity compared to salpingotomy (Strong recommendation, very low quality of evidence).
