Medical abortion was performed in 461 consecutive women with gestational age ≤63 days using a regimen of mifepristone 600 mg followed 2 days later by gemeprost 1 mg vaginally. Success, defined as no surgical intervention, declined from 98.7% after 2 weeks to 94.6% after 15 weeks. The difference in short- and long-term success rates increased with increasing gestational age. The majority of failures (76%) were diagnosed more than 2 weeks after initiation of the abortion. At a 2-week follow-up visit, the women who turned out to be failures had a larger endometrial width, higher β-hCG values and smaller reductions of β-hCG than those treated successfully. To optimize comparison of success rates after different medical abortion regimens, we suggest that the criteria for success are stated clearly, that the success rates are stratified according to gestational age and that the indications for secondary intervention are categorized. |
