Good day. Doctors know what's wrong with unwell organs, hearts, livers, kidneys, lungs... in patients who die with them. There is a shortage of organs. Even a black market. So, perhaps ill organs can be reprocessed outside the body, and put back in to a the original or a new man or woman, can this work?

If organ failure was fatal, then that organ couldn't be "repaired" with our current technology.  We'd probably be better trying to grow new organs from stem cells.

In some cases, there may be other organs that are unaffected by the underlying disease, and things like corneas may routinely be harvested postmortem.

One of the problems is preventing what caused the death of the donor from being a risk to the recipient.  For example, consider kidneys from a cancer patient.  The recipient of the cadaveric kidney would be required to be on immunosuppressant therapy to prevent organ rejection.  If there is any risk of the kidney being infected with the cancer, it would put the recipient in grave danger of developing cancer.  And, perhaps it would be more aggressive due to the immunosuppression. 

Likewise, if the patient had hepatitis related liver cirrhosis, the liver would be shot.  But, all the other organs would also have the risk of carrying the hepatitis virus (not to mention damage caused by the primary hepatitis).  It would be too great of a risk to transplant other organs to another patient.  Unless the recipient had the exact same strain of Hepatitis. 

Accident victims, however, can be tested for diseases, and may have several disease free usable organs.

Perhaps the one bridge between accident and disease would be acute toxic exposure.  Perhaps damaging one organ while sparing others.  It may be that some organs could be essentially "washed" by pumping blood or saline through them, and be made generally safe.

Still, would you wish to have a transplant of an organ that was only 90% ok?  I suppose it depends on how badly you need it.

Yes , sort of ...

Out-of-body operation banishes tumours

For the first time, cancer has been treated by removing an organ from the body, giving it radiotherapy and then re-implanting it. The out-of-body operation allows doctors to administer high doses of radiation to widespread tumours without affecting other organs.

I recall a TV commercial showing the immense build of plaque in the heart of a smoker. Perhaps it can be removed and  cleaned professionally over two minutes and replanted? Including the aorta...?

Not as simple as descaling a washing machine ...
