We report the first series of 9 auxiliary liver transplantations perfo
rmed as a bridge to recovery in 8 patients with fulminant and subfulmi
nant hepatic failure, Hepatic failure was due to hepatitis A virus (n
= 3), hepatitis B virus (n = 1), hepatotoxic drugs (n = 2), autoimmune
disease (n = 1), or it was of unknown origin (n = 1), The donor liver
was reduced to a left lobe (n = 2), a left liver (n = 4), or a right
liver (n = 3), and was implanted in an orthotopic position beside the
native liver after it was resected by a left or a right hepatectomy, C
onventional immunosuppression was used to prevent rejection. Six patie
nts regained normal consciousness within 2 weeks, without any sequelae
. Two patients had persisting encephalopathy due to graft initial dysf
unction, one of whom showed portal vein thrombosis, which was successf
ully cleared, The other one showed hepatic vein stenosis and was retra
nsplanted at day 15, Five of eight patients had to be reoperated becau
se of a surgical complication. Five patients showed rapid regeneration
of their native liver, but one died at day 45 from severe herpes viru
s broncholitis. The auxiliary grafts were removed (n = 3) or left to a
trophy by tapering immunosuppression (n = 1), One patient developed ci
rrhosis of the native liver and died of infectious complications at da
y 42. The native livers of the two remaining patients are still atroph
ic, one at 4 months and one at 1 month posttransplant, Finally, 6 of 8
patients are alive with a follow-up of 1 to 17 months. Four of them h
ave permanently stopped their immunosuppressive therapy. Our experienc
e demonstrates that auxiliary orthotopic liver transplantation (1) is
feasible in children and adults, using either a left or a right liver
graft, (2) is efficient in providing adequate liver function, and (3)
gives a real chance to the native liver to regenerate, offering these
patients a future free of immunosuppression.
