Data from a one year prospective study of thirty-one tubal ectopic pregnancies and ninety-three matched controls is presented. Compared with the controls, a history of induced abortion, was not only statistically significantly more frequent amongst the subjects (P less than 001) but was the Penultimate cyesis in 41.9% of ectopic cases as against 3.2% of the controls (P less than 001). Non-physicians provided 51.6% and 3.3% of induced abortions in the study and control groups respectively. Complications occurred in 51.6% of study population and 6.5% of controls. It is concluded that induced abortions created the predispotion to tubal implantation in the study population and therefore a reduction in the incidence of illegally induced abortion in the community can reduce the incidence of ectopic tubal gestation and tubal infertility.
本文呈现了一项针对31例输卵管异位妊娠患者及93例匹配对照进行的为期一年的前瞻性研究数据。与对照组相比，人工流产史在研究对象中不仅在统计学上显著更常见（P<0.001），而且在41.9%的异位妊娠病例中是倒数第二次妊娠，而对照组中这一比例为3.2%（P<0.001）。在研究组和对照组中，非医生实施的人工流产分别占51.6%和3.3%。研究人群中51.6%出现并发症，对照组中为6.5%。结论是，人工流产使研究人群易发生输卵管着床，因此，社区中非法人工流产发生率的降低可减少输卵管异位妊娠和输卵管性不孕的发生率。
