There's new information coming in today from The Mayo Clinic regarding the Fitterer twins of Bismarck.

Abygail and Madysen Fitterer's condition has been upgraded from Critical to Serious.

The Mayor Clinic in Rochester-Minnesota says post-operative swelling has gone down and that the girls are now being fed through tubes.

On Wednesday, doctors successfully separated the twins who were born last August, conjoined at the chest.

The chief physician says the operation was flawless.

The girls are expected to remain in intensive cares for a few weeks. watch the video | save this article / add to your favorites list
