Abstract
Auxiliary liver transplantation (ALT) has developed as a technique for treating patients with acute liver failure. The surgical techniques of ALT have been refined and current patient survival appears to be similar to that observed with conventional liver replacement for acute liver failure. Our understanding of liver regeneration has improved with experience and it is possible to identify patient and disease groups that are more likely to regenerate and wean off immunosuppression after ALT. Withdrawal of immunosuppression is possible in at least two thirds of survivors up to 4 years post transplant. Young patients have most to gain in the long term from immunosuppression withdrawal. Documentation of liver regeneration should be performed by liver histology, nuclear medicine scanning and CT volumetry. Weaning should be gradual to allow for graft atrophy to avoid complications. ALT has also been utilised for the management of inborn errors of metabolism based in the liver and for other rare problems and these will be briefly addressed in the review. Auxiliary liver transplantation should be considered for the treatment of children with acute liver failure satisfying current criteria for liver transplantation.
