Seven-year-old Heather McNamara was heading home on Tuesday, a month after surgery that temporarily removed organs from her digestive tract to allow removal of a tennis ball-size tumor.

Doctors were able to reimplant Heather McNamara's liver and large and small intestines.

According to her surgical team at New York-Presbyterian Morgan Stanley Children's Hospital, the operation - referred to as an "auto-transplantation" because the patient's own organs (instead of those from a donor) were reimplanted within four hours after being extracted -- is the first of its kind to be performed on a child.
