作者医院从1982年至1991年的10年间,与同期的分娩例数相比,分娩例数增加不明显而宫外孕病例逐年增加。这10年间,前半期(1982年至1986年)宫外孕66例,与后半期(1989年至1992年)99例相比,年龄方面两组无差异;在后半期,在妊娠次数、分娩次数方面减少了1％的危险率。最近国外妊娠分娩少的患者发生宫外孕的有所增加,其原因首先是因性传播疾病(衣原体感染)发病率高所致。性传播疾病引起宫颈炎、附件炎及盆腔腹膜炎,其后遗症使输卵管通路障碍。另一个原因是配子手术增加。至1991年,作者医院经体外受精、胚胎移植的103例妊娠中,因配子操作发生宫外孕的4例(3.9％),其他作者报告的发生率4％～10％。明显高于一般自然妊娠中的宫外孕发生率<0.3％～
Author Hospital from 1982 to 1991, 10 years, with the same period of childbirth compared to the number of cases of childbirth increased not obvious and cases of ectopic pregnancy increased year by year. During these 10 years, 66 cases of ectopic pregnancy in the first half of the period (1982 to 1986) showed no difference in age between the two groups (99 cases in the second half period (1989-1992)). In the latter half, the number of pregnancies and the number of deliveries Reduce the risk of 1%. The recent increase in ectopic pregnancies among foreign pregnancies with fewer births is due in the first place to the high incidence of sexually transmitted diseases (chlamydial infections). Sexually transmitted diseases cause cervicitis, annex inflammation and pelvic peritonitis, its sequelae make tubal access disorders. Another reason is the increase of gametes. By 1991, in 103 pregnancy-induced in vitro fertilization and embryo transfer in the author’s hospital, 4 (3.9%) patients had ectopic pregnancy because of the operation of gametes, and the other authors reported an incidence of 4% -10%. Obviously higher than the incidence of ectopic pregnancy in general natural pregnancy <0.3% ~
