XXXX : surgical separation in 11 cases.

@entity1 @entity7411 @entity299
Eleven pairs of symmetrically conjoined twins underwent surgical separation at the Queen Sirikit National Institute of @entity1 Health. Six were omphalopagus, 4 were thoracopagus and 1 was pygopagus. Eight were female and 3 were male. Three pairs were separated on emergency or semi-emergency bases, and the remaining 8 pairs were separated electively at an older age. Of the 3 pairs who had early emergency separations, one pair, whose combined birth weight was only 2,500 g, underwent emergency separation at the age of 44 days after the death of one twin. The second twin also expired one hour after the separation. In the remaining 2 pairs, early separation was done because of the deterioration of one twin due to @entity299 . In both cases, the @entity1 with @entity299 expired but the others survived the separation satisfactorily. In one pair of @entity7411 , one twin had cyanotic @entity299 . They were electively separated at the age of 2 years and 9 months. The twin with @entity299 expired 2 hours after surgery, but the other survived the separation satisfactorily. In the remaining 7 pairs who underwent elective separations, both twins of each pair survived the separation satisfactorily. However, one twin expired unexpectedly 10 days after the separation.
