There have been 1152 cases of ectopic pregnancy at Kaiser Permanente Hospital from 1953 to 1980. In 200 cases the involved tube was preserved with no surgical complications. There have been 122 subsequent pregnancies, 24 of which were repeat ectopic pregnancies. Twelve were in the involved tube and 12 were in the opposite tube, demonstrating conclusively that both tubes are at equal risk of ectopic pregnancy. Conserving the involved tube does not increase the incidence of ectopic pregnancy but does increase the chances for intrauterine pregnancy in this subfertile population.
1953年至1980年期间,凯撒永久医院共发生1152例异位妊娠病例。其中200例保留了患侧输卵管,未出现手术并发症。后续有122例妊娠,其中24例为重复性异位妊娠。12例发生在患侧输卵管,12例发生在对侧输卵管,这确凿地表明两侧输卵管发生异位妊娠的风险相等。保留患侧输卵管不会增加异位妊娠的发生率,但确实会增加这群生育能力低下人群的宫内妊娠机会。
