The staff at Driscoll Children’s Hospital has cared for the girls since they were transferred to the facility hours after birth at another area hospital.

Dr. Haroon Patel says a team of specialists has been working for months to prepare for the surgery, which could last 12 to 18 hours.

A hospital statement says doctors have a positive outlook for the children’s recovery. The girls will require additional surgeries as they grow.
