作者： J.Spicák S.Vítko M.Ryska RTruneěka M.Krawczyk F.Perner F.Bělina P.Taimr J.Sperl H.Hmcárková Instit.Clin.Exper MedicinePragueCzechRep 不详

The aim of this study was to evaluate the development of LT in Eastern Europe. Representatives of gastro- and hepatological societies answered a questionnaire comprising the most descriptive items of the issue of LT until 1998. The Baltic countries, together with 6 southernBalkan countries, Moldovia and Belarus have not developed a programme of LT. In Ukraine, 7 LT were performed with 3 early deaths.
