Abstract

Background: The ectopic pregnancy (EP) is a public health problem and its frequency has doubled in most industrialized countries in 20 years.
aim: To evaluate the effectiveness of medical treatment of ectopic pregnancy with methotrexate (MTX) intramuscularly (IM).
methods: prospective study supported between October 2006 and December 2010. The selected patients received methotrexate IM (1 mg per kg). The monitoring was based on: the kinetics of plasma HCG, clinical examination and ultrasound. A second injection was performed if hCG on day 4 was increased by more than 25% or J7> the initial rate. Healing corresponded to obtain a zero rate of HCG in a stable manner.
results:We used the first-line medical treatment in 122 patients. The average age of patients was 31.94 years. A haematosalpinx was found in 87.70% of cases. The initial rate of HCG plasma varied between 40 IU/ml and 4088 IU / ml, with an average of 805.88 m IU / ml. The primary success rate obtained after a single injection of intramuscular MTX was 67%. The high success rate obtained after two injections of MTX was 27%. The overall success rate after 1 or 2 injections of MTX was 82%. 17 patients underwent surgical treatment after a first injection of methotrexate. 5 patients underwent surgery after receiving two doses of methotrexate. The period of normalization of plasma levels of h CG was 24 days on average, with extremes ranging from 4 to 43 days for 67 patients cured after a single injection of MTX. This period was 33 days on average, with extremes ranging from 8 to 62 days for patients healed after two injections of MTX.
Conclusion: Medical treatment applied to 38% of ectopic pregnancies diagnosed in our department is effective in 82% of cases if the inclusion criteria are strictly adhered to. Successful treatment is limited by patient compliance and demanding nature of monitoring.
