ABSTRACT
PIP: Between March and September 1988 at the Kenyatta National Hospital in Nairobi, Kenya, clinicians included all patients (127) referred for ultrasonography due to suspected ectopic pregnancy (age range, 18-45 years) in a study to determine whether ultrasonography can be used to accurately diagnose ectopic pregnancy. The researchers examined only the records of 100 patients who had data adequate enough to make a final diagnosis. Based on sonography, clinicians believed 31 women had an ectopic pregnancy, but laparotomy confirmed that just 15 (48.4%) of these women actually had an ectopic pregnancy. Based on sonography, they did not suspect ectopic pregnancy in the other 69 patients, but laparotomy revealed that 2 patients (2.9%) did indeed have an ectopic pregnancy. Thus, the overall ectopic pregnancy rate among the 100 women was 17%. The remaining 83 women had other gynecological conditions. 52.9% of the women with an actual ectopic pregnancy had a pseudogestational sac, which had a positive predictive value of 53% and a negative predictive value of 90%. A pseudogestational sac had a sensitivity of 53% and specificity of 90%. Just 6 ectopic pregnancy cases (35.3%) had an extrauterine gestational sac with a clear fetal pole and a fetal heart beat. An enlarged uterus was more common in women with an ectopic pregnancy than in those with other conditions (82.4% vs. 51.8%; p .05). Every ectopic pregnancy case had a complex adnexal mass compared to just 48.2% of those with other conditions (p .001). When a woman had all these conditions combined--an empty, enlarged uterus; distinct adnexal mass; a pseudogestational sac; and fluid in the cul-de-sac-sonography's positive predictive value increased to 67%. The researchers recommended additional studies using a combination of the urinary pregnancy test and sonography to improve sonography's reliability.
