Predictors of Success of Different Treatment Modalities for Management of Ectopic Pregnancy

Abstract

Aim. The purpose of this study was to investigate factors affecting the success of different treatment modalities for the management of ectopic pregnancy (EP).Methods. One hundred and ninety-seven patients with EP, were included in the study. Patients were treated with either intramuscular methotrexate (Mtx) or surgical treatment.Results. Mtx was applied in 97 (49.2%) patients. In 67 patients (69.1%), a single dose of Mtx and in 30 patients (30.9%) a multiple dose of Mtx was applied. Forty-seven (70.14%) patients were successfully treated with a single-dose Mtx. In the multiple-dose group, the success rate was 70% (21/30 patients). The difference between the success rates was not statistically significant. When the initial serumβhCG value was <1000 mIU/mL, the overall success rate of Mtx treatment was determined to be 86.11%; however, the rate decreased to 42.3% when theβhCG value was >3000 mIU/mL. On the other hand, if the EP mass diameter was <25 mm, the success rate was 89.28% and decreased to 52.63% when it was≥25 mm.Conclusion. The results of the study showed that single-dose treatment with Mtx could be as successful as multiple doses. Overall success of Mtx treatment depended on initialβhCG value and EP mass diameter.
