Ectopic pregnancy in Jos Northern Nigeria: prevalence and impact on subsequent fertility.
BACKGROUND
Ectopic pregnancy remains a major gynaecological problem in contemporary gynaecological practice. Not only do women die from this disease, but also of greater clinical importance is the indirect morbidity of poor fertility prognosis and adverse outcome in subsequent pregnancies. We were interested in documenting the prevalence of ectopic pregnancy and its impact on subsequent fertility.


METHODS
This retrospective descriptive study was done at the Jos University Teaching Hospital. The case notes of all patients who had tubal ectopic pregnancy managed in JUTH between January 1997 and December 2000 were retrieved. Subsequent fertility and reproductive outcome were assessed among women who reported back for follow up fora minimum period of twelve months post surgery. The data was analyzed using frequencies.


RESULTS
During the study period, January 1997 and December 2000 a total of 168 ectopic pregnancies were managed and 9,638 deliveries occurred during the same period. This gives a prevalence rate of 1.74%. Of the 168 cases of ectopics, 130 case records containing relevant information were retrieved (77.4%) and this constituted the sample population for the study. Majority (53.8%) of the women were between 20 and 29 years. Majority of the women were either nulliparous or primiparous (23.8% and 20.0% respectively). Tubal rupture occurred in 86.9% of the women at the time of laparotomy. Total salpingectomy was the surgical modality in 77.7% of the cases. The right fallopian tube was affected in 66.2% and the left 33.8% of the cases. The contralateral fallopian tube was grossly normal in 73.1% of cases. Of the 64 women who were followed up for a minimum of 12 months, 40.6% achieved viable intra uterine pregnancies, 6.3% had a repeat ectopic pregnancy in the contra lateral tube and 53.1% were unable to achieve pregnancy.


CONCLUSIONS
Ectopic pregnancy is prevalent in our environment affecting mainly young women of low parity who desire future pregnancies. The subsequent impact on future fertility of these women could be improved if efforts are focused on early diagnosis to prevent tubal rupture. Early diagnosis prior to rupture offers opportunity for medical management and conservative surgical procedures that are proven to improve future fertility prognosis.
