Asterixis
|
Involuntary flapping movements of the hands associated with metabolic liver dysfunction
|
Balloon tamponade
|
Use of balloons placed within the esophagus and proximal portion of the stomach and inflated to compress bleeding vessels (esophageal and gastric varices)
|
Budd-chiari syndrome
|
Hepatic vein thrombosis resulting in non-cirrhotic portal hypertension
|
Cirrhosis
|
A chronic liver disease characterized by fibrotic changes and the formation of dense connective tissue within the liver, subsequent degernative changes, and loss of functioning cells
|
Constructional apraxia
|
Inability to draw figures in two or three dimensions
|
Fetor hepaticus
|
Sweet, slightly fecal odor to the breath, presumed to be of intestinal origin; prevalent with the extensive collateral portal circulation in chronic liver disease
|
Fulminant hepatic failure
|
Sudden, severe onset of acute liver failure that occurs within 8 weeks after the first symptoms of jaundice
|
Hepatic encephalopathy
|
Central nervous system dysfunction resulting from liver disease; frequently associated with elevated ammonia levels that produce changes in mental status, altered level of consciousness, and coma
|
Orthotopic liver transplantation OLT
|
Grafting of a donor liver into the normal anatomic location, with removal of the diseased native liver
|
Portal hypertension
|
Elevated pressure in the portal circulation resulting from obstruction of venous flow into and through the liver
|
Sclerotherapy
|
The injection of substances into or around esophagogastric varices to cause constriction, thickening, and hardening of the vessel and thus to stop bleeding
|
Variceal banding
|
Procedure that involves the endoscopic placement of a rubber band-like device over esophageal varices to ligate the area and stop bleeding
|
Xenograft
|
Transplantation of organs from one species to another
|
Age related changes of hepatobiliary systemchart 39-1
|
-steady decrease in size and weight of liver, particularly in women- < in blood flow- < in replacement/repair of liver cells after injury- < drug metabolism- slow clearance of hep B surface antigen- > progression of hep C infection and < response rate to therapy- < in drug clearance capability- > prevalence of gallstones due to the increase in cholesterol secretion in bile- < gallbladder contraction after a meal- atypical clinical presentation of biliary disease- more severe complications of biliary tract disease

Technique for palpating the liverfigure 39-3
|
Place one hand under the right lower rib cage and press downward with light pressure with the other hand
