This study includes 347 cases of ectopic pregnancy. A comparison was made between patients having one ectopic pregnancy, those having a repeat ectopic pregnancy, and those whose first pregnancy was an ectopic one. Emphasis was placed on obstetric history and the reproductive future of these patients. Obstetric performance was poor for all groups of patients studied. In the patient whose first pregnancy was ectopic, total reproductive performance was complicated by an increased risk of a repeat ectopic pregnancy. The incidence of repeat ectopic pregnancy was 11.2%. The average interval between ectopic pregnancies was 2.83 years; 80% of the repeat pregnancies occurred within 4 years of the first ectopic episode. Obstetric outcome was likely to be poor after the second ectopic pregnancy.
本研究纳入了347例异位妊娠病例。对单次异位妊娠患者、复发性异位妊娠患者以及首次妊娠即为异位妊娠的患者进行了比较。重点关注这些患者的产科病史和生殖前景。所研究的所有患者组的产科表现均较差。对于首次妊娠为异位妊娠的患者，再次发生异位妊娠的风险增加，使总体生殖表现变得复杂。复发性异位妊娠的发生率为11.2%。异位妊娠之间的平均间隔为2.83年；80%的复发性妊娠发生在首次异位妊娠事件后的4年内。第二次异位妊娠后的产科结局可能较差。
