Hepatic failure after partial hepatectomy due to synergism between endotoxaemia and congestion of the liver.

To determine whether hepatic failure after partial hepatectomy is due to synergism between endotoxaemia and congestion of the liver, we examined endotoxin hepatotoxicity in partially hepatectomized rats with and without congestion of the liver. In partially hepatectomized rats without congestion of the liver, endotoxin administration induced slight elevation of the serum transaminase activity and mild or moderate hepatocellular necrosis in a few rats: these findings were not significantly different from those in sham operated rats treated with endotoxin. On the other hand, in partially hepatectomized rats with congestion of the liver, endotoxin administration induced marked elevation of serum transaminase activity and moderate or severe hepatocellular necrosis in almost all rats: these findings were significantly different from those in endotoxin-treated partially hepatectomized rats without congestion of the liver. These experimental data suggest that synergism between endotoxaemia and congestion of the liver may be a cause of hepatic failure after partial hepatectomy.
