A 7-year-old girl from Long Island, N.Y., is scheduled to leave the hospital and return home a little more than four weeks after receiving a historic surgery that involved the removal and partial re-implantation of six organs in order to resect an abdominal tumor that otherwise would be inoperable. The 23-hour surgery, which began on Feb. 6, was led by Dr. Tomoaki Kato of NewYork-Presbyterian Hospital/Columbia University Medical Center. Dr. Kato and his team of seven surgeons and eight other clinicians removed nearly every major organ in the girl's abdominal cavity — small and large intestines, liver, pancreas, spleen and stomach. Three separate surgical teams worked to remove the tennis-ball-sized tumor, which was tangled around vital organs and essential blood vessels.
