The study reported to the annual conference of the American Society of Anesthiologists, showed that livers regenerated to full size in recipients and donors within two weeks of the operation being performed.
The operation requires the removal of at least 50 per cent of the donor's liver, usually from the right lobe, anesthiologist Dr Mitsuru Nakatsuka, of the Medical College of Virginia, Commonwealth University, Richmond, USA, told the conference.
The procedures that comprised the study were performed between June 1998 and June 1999.
MRI scanning showed that most regeneration took place within a week of the operation. Liver function also returned to normal within a week, Dr Nakatsuka reported.
Recipients discharged after 14 days. 90 per cent survived.
Dr Nakatsuka said that donors were discharged from hospital, on average, after five days. Recipients were discharged after 14 days, on average, and 90 per cent survived.
He told the conference in San Francisco, California, USA: "Successful transplantation depends on the ability to quickly produce normal liver mass and function in the recipient.
"Achieving this involves removing more than 50 per cent of the donor's liver, or at least 0.8 per cent to 1 per cent of the recipient's body weight."
