Context: Female sterilisation is the most widely used method of fertility control in the world. Pregnancy following the procedure is often associated with significant morbidity due to delay diagnosis and management.
Objective: The aim of this study is to examine the peculiarities and factors leading to failed female sterilisation in Ile-Ife Nigeria.
Study Design, Setting And Subjects: A descriptive study of all cases of pregnancy following bilateral tubal ligation encountered at the Obafemi Awolowo University Teaching Hospitals Complex, Ile-Ife, Nigeria from October 1 1987 to September 30 1998.
Main Outcome Measures: Incidence and crude failure rate of female sterilisation, types and methods of sterilisation, types of pregnancy and sterilisation-pregnancy interval.
Results: During the period of study, there were 16,847 births, 533 cases of voluntary surgical contraception and 4 patients with pregnancy following bilateral tubal ligation. The incidence of female sterilisation was 31.5 per 1000 births while the crude failure rate was 7.5/1000. Postpartum and interval voluntary surgical contraception were done in 91.4% and 8.6% respectively. In all the cases of failed female sterilisation, Pomeroy method of female sterilisation was employed and they were all done in the post partum period, with the sterilisation-pregnancy interval ranging from 14 to 42 months.
Conclusion: This study advocates the postponement of tubal sterilisation till 6 weeks postpartum in order to reduce the failure rate.and the use of techniques that involve burying the outer ends of the fallopian tubes in the broad ligament if sterilisation is done in the immediate puerperium.
