Ovarian pregnancy - A 12-year experience of 19 cases in one institution

Objectives: To report the prevalence, presentation, diagnostic modalities, and treatment of ovarian pregnancy in one institution. Study design: Retrospective case control study of 19 cases of ovarian pregnancy treated between 1990 and 2001 at Assaf Harofeh Medical Center, Zerifin, Israel. Main outcome measures: Prevalence, presentation, diagnostic modalities, surgical treatment, and relation to intrauterine device (IUD) use. Results: Nineteen ovarian pregnancies, diagnosed between 1990 and 2001, comprised (19/694) 2.7% of all ectopic pregnancies, 1:3000 of all live births leading to a mean ovarian pregnancy per year of 1.6. Presenting symptoms were similar to those of tubal pregnancies including circulatory collapse which was present in 4/19 (21%) of patients. Culdocentesis for diagnostic purposes, has become an unnecessary procedure. Wedge resection by laparotomy was the treatment of choice in the past, and from 1994, it was performed exclusively by laparoscopy. When an ovarian pregnancy was diagnosed, intrauterine device was present in 68% of the patients and in 76% of the fertile women. Conclusions: The absolute number of ovarian pregnancies between 1900 and 2001 increased but the prevalence rate per delivery was stable. Despite modern diagnostic modalities patients still present in circulatory collapse-conservative approach may underestimate the potential risk of bleeding. Culdocentesis has no clinical diagnostic benefits. Laparoscopy is invaluable, as diagnosis and treatment can be carried out as a single treatment. Laparoscopic wedge resection is the treatment of choice. The relation between IUD use and ovarian pregnancies is still strong.
