OBJECTIVES: Ectopic pregnancy occurs when the embryo fails to implant within the uterine cavity. Methotrexate, a folic acid antagonist has been widely used to treat ectopic pregnancy. The aim of this study is to determine the efficacy of methotrexate treatment for ectopic pregnancies in our settings which will in-turn help us reduce maternal mortality and morbidity. METHODS: This was a retrospective review of 60 cases of ectopic pregnancy treated with single dose methotrexate in Nizwa hospital, Oman. Demographic data, clinical presentation, treatment progress, outcome, side effects and future fertility follow up were analysed using a computer database. Selection criteria included hemodynamically stable women with ß-hcg level of ≤5000 mIU/ml, adnexal mass ≤4 cm, absent cardiac activity and hemoperitoneum less than 100 ml. Human chorionic gonadotrophin (hcg) assay and clinical presentation were used to determine cases which warranted surgical intervention. RESULTS: The success rate of single dose methotrexate therapy in our study was 65% (n=39) and 35% (n=21) required surgical intervention compared to reported success rate of 67-100% published in various studies. Careful selection of cases and confining strictly to the criteria improved the success rate from 40% to 60% in five and half years of the study. The mean average time of resolution of ectopic pregnancy was 32 days for a single dose and 58 days for repeat second or third doses. Eight cases of pregnancy of unknown location were treated successfully with Methotrexate. No major side effects were noted. A successful fertility outcome of 30% in the first year followed by 13.3% in the subsequent second year with a secondary infertility rate of 11.6% was observed in this study. CONCLUSION: Methotrexate treatment of ectopic pregnancies is safe and effective with no major side effects. Intramuscular methotrexate has the advantage of tubal conservation and saves patients from requiring surgery. It is easier to administer than intraoperative route, which is by laparoscopy and needs expertise. Our study showed single dose methotrexate to be an effective treatment option for selected patients with unruptured tubal ectopic pregnancy.
