Abstract
RESEARCH QUESTION What is the time required for complete physical resolution of tubal ectopic pregnancies diagnosed on ultrasound imaging in women undergoing successful expectant management? DESIGN A prospective observational cohort study of 177 women who had successful expectant management of tubal ectopic pregnancy, who attended a single Early Pregnancy Unit between January 2014 and December 2018. All participants were monitored until their serum β-hCG dropped to non-pregnant levels and with two-weekly follow-up ultrasound scans until resolution of the pregnancy. RESULTS 112/177 (63.8%, 95% CI 56.3-70.9) of tubal ectopic pregnancies were indiscernible on ultrasound 2 weeks after serum β-hCG had returned to non-pregnant levels. In 8/177 (4.5%, 95% CI 2.0-8.7) physical resolution took longer than 78 days. There was a positive correlation between biochemical and physical resolution of tubal ectopic pregnancy (r=0.21, p=0.006). CONCLUSIONS Physical resolution of tubal ectopic pregnancy is often prolonged and is positively correlated with initial and maximum β-hCG levels. Our results indicate that β-hCG resolution cannot be used as the end-point of expectant management of tubal ectopic pregnancy, which should be considered when counselling women and planning for future pregnancies. KEY MESSAGE In a significant proportion, physical resolution of tubal ectopic pregnancy takes several weeks following the return of serum β-hCG to non-pregnant levels. Women should be advised to delay trying for another pregnancy for three months, to avoid resolving pregnancies being misdiagnosed as new ones and to reduce the theoretical risk of recurrent ectopic, due to temporary tubal blockage by the resolving trophoblast.
