1974년 1월 1일부터 1983년 12월 31일까지 만 15년간 국립의료원 산부인과에 입원해서 Spieqelberg의 네가지 조건을 만족하는 난소임신 11예를 분석하여 다음과 같은 결론을 얻었다. 1. 난소임신은 자궁외임신의 1.8%를 차지하였으며 분만 1,022예 중 1예에 해당되었다. 2. 평균년은 난소임신에서 45.4%, 난관임신에서 54.6%이었다. 3. 불임을 호소한 경우는 난소임신에서 0%, 난관임신에서 4.1%이었다. 또한 자궁내장치를 사용하였던 예는 난소임신에서 18.1%, 난관임신에서 3.1%이었다. 4. 과거에 자궁내막 소파검사를 받았던 경우는 난소임신에서 54.5%, 난관임신에서 71.2%였으며, 기왕 개복수술 환자는 난소임신에서 0%, 난관임신에서 17.6%이었다. 5. 과거력상 또는 수술시 혹은 조직검사상 골반염이 있었던 경우는 난소임신에서 18.1%, 난관임신에서 8.3%이었고 자궁내막증이 같이 있었던 경우는 난소임신에서 0%, 난관임신에서 0.4%이었다. 6. 정상 월경일로부터 수술하기까지의 기간은 난소임신이 평균 52.8일, 난관임신이 평균 54.6일이었다. 7. 증상으로는 복부통증이 100%로 가장 많았고 그 외 강출혈이 7예, 무월경 2예, 복부종괴 2예, 쇼크 1예 순이었다. 임신반응검사는 3예에서 시행하였었는데 2예(66.6%)에서 양성으로 나왔다. 8. 복통이 있는 날 수술했던 경우는 5예(45.4%)이었으며 500ml이상의 복강내 출혈이 있는 경우가 72.7%를 차지하였다. 9. 수술시 진단은 난소임신이 18.2%, 난소출혈이 81.8%이었으며 수술은 난소난관적제술이 63.6%, 난소적제술이 18.2%, 난소부분적제술이 18.2%를 차지하였다.

Ovarian pregnancy is a uncommon form of ectopic pregnancy that must bedodumented by the four postulates of Spiegelberg, which establish that the pregnancy is in the ovary and does not involve the tube. Awareness of the possibility of ovarian pregnancy and closed histologic examination of surgical specimen are critical factors for increased recognition. Mant authors reported that the use of intrauterine contraceptive devices was not associated with an absolute increase in occurrence of ovarian pregnancy. This study was undertaken to investigate 11 cases of ovarian pregnancy which were admitted to the Department of Obstetrics and Gynecology, in National Medical center, fron Jan. 1, 1974 to Dec. 31, 1983.The results were as follows: 1. The incidence of primary ovarian pregnancy was 1.8% of all ectopic pregnancies or 1 in 1,022 deliveries. 2. Average age was 30.0 years and multiparity was 45.4% of the cases. 3. Infertility was not present in this series and 1.8% of the cases had used intrauterine contraceptive devices. 4. A history of previous dilatation and curettage occurred in 54.5% and no history of previous laparotomy in the present series. 5. A history or operative or histologic confirmation of past pelvic inflammatory disease occurred in 18.1% of the cases and associated endometriosis was not present in this series. 6. Average day for last normal menstural period to operation was 52.8 days. 7. Clinical symptoms were abdominal pain(100.0%), vaginal bleeding(63.6%), skipped mensturation(18.1%) and clinical shock(9.0%). Prgnancy tests were positive in 2 out of 3 cases. 8. Operation is performed with the first episode of pain 45.4% and the hemoperitoneum was over 500ml in 72.7% of the cases. 9. A correct surgical diagnosis was made in only 18.2% of the cases. Salpingo oophorectomy was performed in 63.6% and oophorectomy in 18.2% and wedge resection or enucleation in 18.2% of the cases.
