Abstract/OtherAbstract:
The major theme of this discussion is how portal pressure after portosystemic shunt procedures may modulate the expression of hepatic encephalopathy. Decades of emphasis on the paramount importance of maintaining portal venous perfusion after shunt procedures is now being re-examined. In countries where non-cirrhotic portal hypertension is common, physicians have long recognized that hepatic encephalopathy is rare even with total portosystemic shunting. However, once decompressive shunts are created, hepatic encephalopathy becomes a clinical problem. Why this occurs needs to be better understood. In the meantime, there has been virtual abandonment of surgical shunts in favor of endoscopic variceal ablation treatment. This is despite the fact that surgical shunts that only partially decompress the portal hypertension are associated with excellent long-term control of variceal bleeding and low rates of hepatic encephalopathy. The time has come to once again examine the key relationship between portal pressure, portal perfusion with hepatic arterial inflow in inducing hepatic encephalopathy after creation of portosystemic shunts.
