Native hepatectomy after auxiliary partial orthotopic liver transplantation.

In countries where a living donor is the only source of the graft, the limited size of the graft is of serious concern when considering extending the procedure to adult recipients. In order to overcome this problem, auxiliary partial orthotopic liver transplantation (APOLT) was applied to the concept that the residual native liver would support the graft function until the graft expanded enough to work by itself. We herein report on a 20-year-old woman with primary sclerosing cholangitis (PSC), who received a small-size liver graft by APOLT. Computed tomography and scintigraphy showed that the graft had regenerated sufficiently 1 month after the operation. The diseased residual native liver is potentially carcinogenetic. Therefore, second-stage native hepatectomy was done 35 days after the first operation. Histopathologic examination of the resected native liver revealed biliary cirrhosis with PSC but no evidence of cholangiocarcinoma. Second-stage native hepatectomy after APOLT seems to be a curative treatment for chronic end-stage liver disease with graft size mismatch that may be as good as orthotopic liver transplantation.
