Preliminary experience with living donor liver transplantation in adults and children.
BACKGROUND
Living donor liver transplantation (LDLT) is becoming a widespread technique with good results. Its use may sharply decrease waiting list mortality. However, donor safety is of primary concern. The aim of this work was the preliminary evaluation of the LDLT program initiated in our institution in 1995.


METHODS
Among 875 liver transplants (LT) performed from 1986 12 are LDLT in nine adults (50.0+/-10.0 years) and three children (1.9+/-1.1 years). All donors were relatives: son/daughter (six), brother (three), and father/mother (three).


RESULTS
Donor right lobe graft weight was 758.3+/-137.4 g; left liver 525.3+/-97.1 g; and left lobe 293.3+/-30.5 g, with a graft weight/recipient weight ratio of 0.91+/-0.21 (0.64-1.36) in adults. Complications in five donors (42%) included biliary fistula in the first three cases, two pleural effusions and one intra-abdominal collection. Mean hospital stay was 16.9+/-15.2 days (median 12). Recipient indications for adults were: four HCV cirrhosis (+ alcoholic in one), one HBV cirrhosis, one cryptogenic, one alcoholic, one PBC, and one retransplant due to cholangiopathy. In children, the etiologies were two biliary atresia and one liver fibrosis. The first case was the only mortality (8.3%). Two patients were retransplanted (16.6%) due to arterial thrombosis (AT) and graft dysfunction. Actuarial survival at 1 year was 91.7%+/-8.0% for patients and 83.3%+/-10.8% for grafts. Complications in the recipients included AT (two), Acinetobacter sepsis, jaundice and upper digestive hemorrhage (due to a "small-for-size" graft), biliary fistula after T-tube removal, volvulus around the T tube, and intra-abdominal collection.


CONCLUSIONS
Our experience suggests that good results can be achieved with LDLT. Standardization of the technique will allow refinement of the operation and decrease waiting list mortality. However, donor safety remains a fearful threat.
