[Segmental liver transplantation. Experimental studies in swine].

Authors report the results of an experimental application of one of the more recent techniques of liver transplantation, which has the preparation ex situ as a basilar step of the procedure. 18 pig were operated on, from september 1991 to march 1993; they were divided in two groups: the first (group A) underwent an auxiliary segmental autotransplantation of left lobe to heterotopic subdiaphragmatic location; in group B an orthotopic segmental autotransplantation of right lobe after ex situ preparation of the liver according the technique of Pichlmayr was performed. The results show that a bigger application of ex situ surgery may help to find a resolution to the problem of the small number of liver donation.
