Vietnamese and foreign doctors have successfully removed a 90-kilogram tumor from a man in a 10-hour operation at Ho Chi Minh City's FV Hospital Thursday.
Nguyen Duy Hai, 32, of Dalat underwent the operation to remove easily the biggest tumor ever recorded in Vietnam.
The surgery started at 8:55 a.m. and ended at 7:30 p.m., and was broadcast live by US' Morningstar Entertainment.
Hai's mother Nguyen Thi Cho Con, who was watching the surgery on a TV screen outside the operation room, burst into tears when it ended upon seeing Hai's heart beating.
"I am walking on clouds now," she said.
Dr. McKay McKinnon, a renowned US plastic surgeon, led the surgery team.
Dr. Gerard Desvignes, medical director of FV Hospital, had said earlier that tests showed the patient was in good enough health for such a risky surgery.
Hai will remain in the intensive-care unit for at least a week now. Doctors hope his heart and lungs will function normally.
The treatment is estimated to cost VND420 million (US$19,970), but FV Hospital has charged only VND252 million, which was contributed by the Dalat City Red Cross and other donors.
Dr McKinnon performed the surgery free of charge.
Hai has been diagnosed with neurofibromatosis type I (NF-1), formerly known as von Recklinghausen disease, a genetic disorder.
He was normal at birth, but his right leg grew much bigger than his left leg by the time he turned four.
After doctors amputated his right leg 14 years ago, a tumor kept growing and has since covered portions of his buttocks and back.
Last July, when Hai was admitted to the HCMC Tumor Hospital, the tumor weighed about 80 kg, but since then grew to 90 kg.
Hai had to remain in a permanent sitting position even when he slept and rely on his mother for all his needs.
He lived with the tumor because his family could not afford surgery to remove it.
