Living organ donors risk lives to save others

HONG KONG (Reuters) - While other teenagers were celebrating their high-school graduation, 18-year-old James Chan was in hospital donating most of his liver to his father.

"I didn't give it a second thought. It was just something I had to do because my sister was too young (to take the risk)," said the apprentice electrician, who is now 26.

A worldwide shortage of organs has forced many people with end-stage illnesses to rely on living donors -- either relatives, or strangers from poorer countries where organs can be obtained cheaply -- to donate kidneys, liver sections, lung lobes, skin and bones for grafts.

But the complications and risks for donors -- including bleeding, infection and in some cases death -- mean that many donors find their own health deteriorating after the operations.

"Apart from complications, there is risk of death. In the world's medical literature, we know of 15 (living liver) donors who died after the operation," Lo Chung-man, professor for hepatobiliary and pancreatic surgery at the University of Hong Kong, told Reuters in a recent interview.

For living liver donors, removing one-third of the organ, or the left lobe, carries a 0.1 percent risk of death, while removing the right lobe, or two-thirds of the liver, carries a 0.5 percent risk of death, or 1 chance in 200.

"We are considering someone completely healthy who has no need for the operation and you put him at the risk of death, or 1 chance in 200. For a healthy person, any risk of death is not acceptable," Lo said.

"Our principle is to do no harm, but when we do a living donor operation, we are doing harm to the donor. We are converting him from a healthy person to a sick patient."
