India's first surgery to separate head-joined twins starts

In a first, 40 doctors at AIIMS, New Delhi, began surgery to separate 28-month-old twins joined at the head on Monday. Craniopagus conjoined twins occur once in 25 lakh live births while 40% of them die at birth. The two-phase surgery is expected to last 50 hours and "even if one survives, it'll be a historic achievement", said a doctor.
