Two-month-old twins Preslee and her conjoined sister Kylee were on their separate two bodies after the operation conducted on them by a team of 15 doctors and medical staff at the Children's Hospital of Oklahoma University Medical Center. The two were recuperating in separate cribs lying side by side.

"We waited because we wanted the organs to get a little bigger, a little stronger. The primary concern was cardiac connection," hospital spokesman Allen Poston disclosed to the media.

The cardiac imaging had revealed that the heart had very little connection but it was the liver which was posing difficulty and complication. Both the girls were using the same liver. The twins were entwined at the chest as well but shared no major blood vessel. 

The girls born on 25 October in the Oklahoma University Medical Center are still under observation in the hospitals' neonatal intensive care unit. Their condition is still critical.

But the father Kyle Wells could not conceal his happiness and said in a statement, "We are very thankful to the physicians and surgical staff at Children's Hospital."
