摘要：Background: Conjoined twinning is the most fascinating condition that affects human being as well as ani- mals 1,2,3 . Their images have been found in cave drawings and carvings many centuries back. Like all monozy- gotic twins, conjoined twins are always of same sex. It is a fairly rare occurrence, exact statistics are not known, but are estimated to be 1 in 200,000 live births 4 with a higher incidence in India and Africa. It is estimated that about 70 percent of conjoined twins are females. Approximately 40 to 60 percent of conjoined twins are still- born, and about 35 percent survive only one day. The overall survival rate of conjoined twins is between 5 to 25 percent.
