DHAKA-Bangladeshi twins born conjoined at the skull will undergo a difficult and potentially dangerous operation to separate them, surgeons said Wednesday as they appealed for help from global medical experts. Doctors are trying to establish whether the one-year-old girls, born otherwise healthy in northwest Bangladesh, share the same brain, something that would vastly complicate the surgery. “It would be a very delicate and sensitive surgery,” said Ruhul Amin, chief paediatric surgeon at Bangabandhu Sheikh Mujib Medical University in the capital Dhaka. “We’re evaluating their condition and trying to contact experts across the world for opinions and help.” Their parents, both schoolteachers, came to Dhaka shortly after Rabia and Rukia were born, to seek medical help. Amin said the girls were healthy and playful but he wanted more time to study their condition to minimise the risks of surgery as much as possible. The parents did not even know they were having twins before the birth, with scans not revealing any abnormalities or indications of two children, said their father Rafiqul Islam. “The doctor only said it was a baby with a bigger head,” he told AFP.
