Ectopic pregnancy (EP) occurs when a fertilized ovum implants outside of the uterine cavity. It is a common cause of morbidity and mortality in women of reproductive age in the first trimester. It affects 1-2 in every 100 pregnancies and is responsible for 10% of all maternal deaths. The exact etiology of ectopic pregnancy is unknown. Whilst the incidence of EP is increasing, the associated morbidity and mortality has decreased. EP should be considered in any patient presenting early in pregnancy with vaginal bleeding or lower abdominal pain in whom intrauterine pregnancy has not yet been established. 97% of all ectopic pregnancies are tubal; the remaining 3% are non-tubal.
