Abstract:
Left liver grafts are now seldom used for adult recipients of living donor liver transplantations because the left liver is believed to be insufficient to meet patient metabolic demands. At the University of Tokyo Hospital, left liver grafts have been limited to patients with fulminant hepatic failure or chronic hepatic failure with a model for end-stage liver disease (MELD) score of less than 15. Since 2000 25 adult patients received left liver grafts. The mean graft weight to standard liver volume ratio was 44%. The rates of acute rejection, vascular, and biliary complications were 24%, 0%, and 25%, respectively. All patients survived the operation and are doing well with a mean follow-up of 17 months. The present results suggest that left liver grafts provide acceptable results among patients satisfying our criteria.
