title: A comparison of the incidence, presentation, and management of ovarian pregnancies between two periods of time.
abstract: OBJECTIVE
  To compare the prevalence, presentation diagnostic modalities, and management of 37 ovarian pregnancies in one institution during two time periods.
  
  
  METHODS
  A retrospective study (Canadian Task Force classification II-2).
  
  
  METHODS
  Department of Gynecology in a university-affiliated hospital.
  
  
  METHODS
  Twenty patients with ovarian pregnancy between 1971-1989 compared with 17 patients with ovarian pregnancy between 1990-2000.
  
  
  RESULTS
  Seventeen ovarian pregnancies, diagnosed between 1990-2000, comprised 2.6% (17/634) of all ectopic pregnancies, 1:3500 of all live births leading to a mean ovarian pregnancy rate per year of 1.5, as opposed to 3.1% (20/647) of all ectopic pregnancies, 1:3600 of all live births, and a mean ovarian pregnancy rate per year of 1.1 in the previous period. Circulatory collapse was present in 4/17 (23%) patients in the 1990-2000 time period and in 6/20 (30%) in the previous period. Culdocentesis for diagnostic purposes was practically abandoned in the recent decade. Wedge resection by laparotomy was the treatment of choice in the past, and after 1997, it was performed exclusively by laparoscopy. When an ovarian pregnancy was diagnosed, an intrauterine device (IUD) was present in 65% of all patients and in 73% of women who had previously conceived in the 1999-2000 time period, compared with higher rates in the previous period (90% and 100%, respectively).
  
  
  CONCLUSIONS
  The absolute number of ovarian pregnancies in the last 11 years increased when compared with the previous 19 years; however, the prevalence rate per delivery was stable. Patients still experienced circulatory collapse despite modern diagnostic modalities. Culdocentesis for diagnostic purposes has become an unnecessary procedure. Laparoscopic wedge resection was the treatment of choice. The relationship between IUD use and ovarian pregnancies was still strong.
