Conjoined twins are rare phenomena occurring in one in 1 in 50,000 live births. 
Successful surgical separation of conjoined twins is a major undertaking 
requiring careful planning by a multidisciplinary team. Reports of seperation of 
joined twins in developing countries like Nigeria are rare. Ten cases of 
conjoined twins were separated between 1936 and January 2003 (including the 
authors two new cases). There were five omphalopagus, two pygopagus, two 
heterpagus and one ishiopagus twins. Three underwent emergency separation with 
83.3% mortality while seven underwent elective seperation with 64.3% survival. 
The overall mortality rate was 50%. Despite the absence of advanced 
technological resource selected group of conjoined twins can be successfully 
separated in a developing country like Nigeria. An improvement in facilities and 
availability of trained personnel in likely to be associated with improved 
outcome.
