    Author: Tulandi T, Atri M, Bret P, Falcone T, Khalife S.
    Journal: Fertil Steril; 1992 Jul; 58(1):98-100. PubMed ID: 1624030.
    Abstract:
    OBJECTIVE: To evaluate the efficacy of transvaginal intratubal methotrexate (MTX) treatment of tubal ectopic pregnancy (EP). SETTING: Outpatient setting in University Hospital. PATIENTS: Forty women with early EP and rising serum beta-human chorionic gonadotropin (beta-hCG) levels. INTERVENTION: Transvaginal intratubal administration of MTX (1 mg/kg body weight). MAIN OUTCOME MEASURES: Success was defined as declining serum beta-hCG to undetectable levels, no tubal dilatation on ultrasound examination, and no further intervention was required. RESULTS: Treatment was associated with a 70% success rate. No difference was found in the success rate between women with an embryo (76.9%) and those with no embryo in their fallopian tubes (66.7%). The initial serum beta-hCG levels were also not different between patients who were successfully treated and those who failed to respond to the treatment. Despite declining serum beta-hCG levels, tubal rupture occurred in two patients. CONCLUSIONS: Treatment of EP by transvaginal MTX administration is associated with a 70% success rate. This is independent of the presence of an embryo or the initial serum beta-hCG levels. Rupture of EP can still occur despite low and declining serum beta-hCG levels.
