RESUMEN
Background: Conjoined twinning is a rare congenital anomaly. We present here; our experience in the management of two sets of conjoined twins at a Teaching Hospital in north central Nigeria. Method: Data of conjoined twins managed at the Jos University Teaching Hospital in 1987 and 2004 were retrospectively collated and analyzed. Result: Two sets of pyopagus tetrapus conjoined twins were managed within the period; one was a set of triplets. The conjoined pairs in both sets of twins were females. None of the twins was diagnosed prenatally. Both sets of conjoined twins were delivered spontaneously by vaginal route. Emergency surgical separation was undertaken in both sets be- cause of deteriorating anencephaly in one twin in the first set and anorectal malformation and intestinal obstruction in one twin in the second set. Both sets of twins died after separation. Conclusion: Our experience showed that separation of conjoined twins may be associated with high mortality. Sepsis and electrolyte imbalance appear to be the major causes of morbidity and mortality; particularly when the resultant skin defects are large
