A set of conjoined twin girls with a single body and two heads has been born at a Chinese hospital, and doctors said it would be nearly impossible to separate them. A staffer at the Suining City Hospital in Sichuan, who only gave her name as Wang, said the parents didn't want to have the babies at first for fear that they could not keep them alive. Wang said the girls have been transferred to a hospital in Chongqing to be examined by experts. The girls weigh 9 pounds and measured 20 inches. They have two spines and two esophaguses but share other organs—making it nearly impossible to separate them.
