IUD 增加了宫外孕的发生率,其中90～99%为输卵管妊娠,因此作者决定对置 IUD 和未置 IUD 也未使用 OC 的非孕妇女的输卵管粘膜作一比较研究。参与研究的28名健康非孕妇女于剖腹或腹腔镜作输卵管结扎时,切取1cm 长的输卵管峡部.其中12名置 IUD>6个月(5名为 CuT,4名为 Multi-loads,1名为 Lippesloop,2名为普通 IUD),其余16名未置 IUD 也未用 OC,作为对照组。二组的年龄分布、孕次和产次相仿。置 IUD 组中2例以前曾患过输卵管炎。切下的输卵管标本经固定后切片作光镜和扫描电镜检查。
IUD increased the incidence of ectopic pregnancy, of which 90 to 99% of tubal pregnancy, so the authors decided to place IUD and without IUD nor OC in non-pregnant women with tubal mucosa for a comparative study. A total of 28 healthy non-pregnant women undergoing laparotomy or laparoscopy for lumbar tubal lumbar dissection received 1 cm of tubal isthmus, 12 of whom had IUD> 6 months (5 CuTs, 4 Multi-loads, 1 Lippesloop and 2 normal IUDs), and the remaining 16 non-IUDs and no OCs served as controls. The two groups of age distribution, parity and parity times similar. Two patients in the IUD group had previously had salpingitis. The cut tubal specimens were fixed after slicing for light microscopy and scanning electron microscopy.
