Ch. 36 GI - Book/3 Flashcards
accumulation of ascitic fluid causes
3
- abdominal distention
- increased abdominal girth
- weight gain
what causes light colored stool
the complete obstruction of bile flow from the liver to the duodenum
causes of ascites include
6
- cirrhosis #1
- heart failure
- constrictive pericarditis
- abdominal malignancies
- nephrotic syndrome
- malnutrition
long term portal HTN problems include
5
- varices
- splenomegaly
- ascites
- hepatic encephalopathy
- hepatopulmonary syndrome
obstructive jaundice can result from
2
extrahepatic (post) or intrahepatic obstruction
partial obstruction of bile flow from liver to duodenum results in what stool
normal in color
jaundice in newborns is caused by
impaired bilirubin uptake and conjugation
obstruction of bile canaliculi can cause
intrahep obstructive jaundice
itching aka
pruritus
intrahep obstructive jaundice involves
2
- disturbances in hepatocyte function
2. obstruction of bile canaliculi
several factors contribute to the development of ascites
4
- portal HTN
- decreased synthesis of albumin by the liver
- splanchnic arterial vasodilation
- renal sodium and water retention
most common cause of portal HTN is
fibrosis and obstruction caused by cirrhosis of the liver
decreased bilirubin uptake or conjugation causes
unconjugated hyperbilirubinemia
disorders of bilirubin metabolism (unconjugated bilirubin) can be caused by
2
- drug induced
2. hereditary disorder
pruritis aka
itching
icterus aka
jaundice
hemolytic jaundice causes
hemolytic anemias i.e. sickle cell
10% of people with ascites develop what
bacterial peritonitis
hyperbilirubinemia and jaundice can result from
3
- extrahepatic (posthepatic) obstruction to bile flow
- intrahepatic obstruction
- prehepatic excessive production of unconjugated bilirubin
portal HTN is caused by
disorders that obstruct or impede blood flow through any component of the portal venous system or vena cava
hepatic encephalopathy results from a combo of
biochemical alterations that affect neurotransmission and brain function
the complete obstruction of bile flow from the liver to the duodenum causes
light colored stool
most common cause of ascites
cirrhosis
excessive hemolysis of RBC can cause
hemolytic jaundice (pre or nonobstructive)
portal HTN is
abnormally high BP in the portal venous system caused by resistance to blood flow
complications common to all liver disorders
5
- portal HTN
- ascites
- hepatic encephalopathy
- jaundice
- hepatorenal syndrome
abnormally high BP in the portal venous system caused by resistance to blood flow
portal HTN
extrahep obstructive jaundice develops if
the common bile duct is occluded
what accompanies jaundice because bilirubin accumulates in the skin
pruritus/itching
hepatic encephalopathy - ammonia cannot be converted to
urea
what lab evaluation establishes whether elevated plasma bilirubin is conjugated or unconjugated or both
serum levels
disorders that obstruct or impede blood flow through any component of the portal venous system or vena cava
portal HTN
ascites - portal HTN and reduced albumin levels cause
capillary hydrostatic pressure to exceed capillary osmotic pressure, pushing water into the peritoneal cavity
two common things that occlude bile duct
- inflammation
2. gallstone
jaundice is caused by
hyperbilirubinemia
portal HTN intrahepatic causes result from
7
- vascular remodeling with shunts
- thrombosis
- inflammation
- fibrosis
- biliary cirrhosis
- viral hepatitis
- schistosomiasis (parasitic infection)
portal HTN posthepatic causes occur from
2
- hepatic vein thrombosis
2. cardiac disorders that impair the pumping ability of the right side of the heart
jaundice aka
icterus
bacterial peritonitis from ascites sx
5
- fever
- chills
- abdominal pain
- decreased bowl sounds
- cloudy ascitic fluid
sx from jaundice of viral of bacterial inflammation in the liver
3
- fever
- chills
- pain
urine may be what, several days before the onset of jaundice
darker
