Trishna and Krishna, the formerly conjoined twin sisters successfully separated in a mammoth operation last month were discharged from the hospital today just in time to celebrate their third birthday.

Doctors at the Royal Children's Hospital in Melbourne said the little girls had made a remarkable recovery since their surgery five weeks ago and were already toddling around the hospital with their walking frames.

"I look forward to seeing them live a long and happy life; that's my wish for them," neurosurgeon Wirginia Maixner said in a statement released by the hospital.

The twins, who were rescued from an orphanage in Bangladesh two years ago and taken to Australia for the life-saving surgery, were connected at the top of their skulls and shared blood vessels and brain tissue.

The 32-hour operation to separate them was the culmination of a two-year schedule of procedures which include five other operations, including a 20-hour session to separate the blood vessels.

They will spend their birthday tomorrow at home in Melbourne with their legal guardian, Moira Kelly.
