Ectopic pregnancy.

H P Robinson, L C de Crespigny

    Clinics in Obstetrics and Gynaecology
    |December 1, 1983

    Summary
    This summary is machine-generated.

    Diagnosing ectopic pregnancy is challenging. Ultrasound combined with pregnancy tests and hCG assays improves accuracy, especially when an empty uterus is seen with an adnexal mass or pelvic fluid.

    Area of Science:

    • Obstetrics and Gynecology
    • Diagnostic Imaging
    • Reproductive Medicine

    Background:

    • Ectopic pregnancy is a major cause of maternal mortality and morbidity.
    • Diagnosis remains challenging despite obstetrician awareness.
    • Diagnostic ultrasound has become crucial in evaluating suspected ectopic pregnancies.

    Purpose of the Study:

    • To assess the diagnostic utility of ultrasound in conjunction with biochemical markers for ectopic pregnancy.
    • To propose a rational management scheme for suspected ectopic pregnancy in stable patients.

    Main Methods:

    • Utilizing diagnostic ultrasound to assess for intra-uterine pregnancy, empty uterus, adnexal masses, and pelvic free fluid.
    • Correlating ultrasound findings with urine pregnancy tests and serum beta-subunit hCG assays.

  • Analyzing diagnostic accuracy based on combined clinical and biochemical data.

    • Main Results:

    • An empty uterus with an adnexal mass and/or pelvic free fluid, alongside positive biochemistry, achieved 95% diagnostic accuracy for ectopic pregnancy.
    • An empty uterus alone, even with positive biochemistry, was not a reliable indicator.
    • A visible extra-uterine fetus confirmed ectopic pregnancy (6% of cases); a negative serum hCG virtually excluded it.

    Conclusions:

    • A combined approach using ultrasound, urine pregnancy tests, and serum hCG assays enhances diagnostic accuracy for ectopic pregnancy.
    • Management strategies should integrate these findings for stable patients.
    • Surgical intervention remains paramount when a patient's condition necessitates it, regardless of ancillary test results.
