The 29-month-old Rocha girls twin girls that were formerly conjoined at the chest and abdomen are back at home in Costa Rica.

Yurelia and Fiorella Rocha-Arias were separated by surgery at Lucile Packard Children's Hospital at Stanford in November and flew back home yestaerday.

The girls arrived in the Bay Area in July and began receiving weekly injections of sterile salt water into balloons placed under their skin. The procedure stretched the skin to compensate for the holes surgeons cut into their abdomens.

After the separation surgery, Yurelia needed follow-up heart surgery to correct some deformities. After the operations, her heart started to function normally.

Researchers estimate the incidence of conjoined twins to be between 1 in 30,000 to 1 in 200,000 worldwide.

Yesterday, Yurelia and Fiorella Rocha were walking, talking and playing which each other when arriving back home to Costa Rica.
 
Mom said, two days prior to arriving home, the girls were taken to Disney Land. What every child who comes to America wants to do.
