Six-month-old twin girls who were surgically separated last month were released from the hospital Saturday and could return home in a few days, the Mayo Clinic said.

Abbigail and Isabelle Carlsen joined their parents, Jesse and Amy Carlsen, at the Ronald McDonald House, which provides care for children who have been treated at the Mayo Clinic.

The family was scheduled to return to its home to Fargo, N.D., on Tuesday.

A farewell celebration for the twins was planned for Monday at the hospital.

The girls were born Nov. 29 attached at the diaphragm, pancreas and liver. They also shared a common bile duct and part of an intestine. They were separated May 12.
