Abdomen Flashcards
Chronic diarrhea duration
lasting 4 weeks or more
chronic diarrhea is typically noninfectious in origin, as in
Chronhs disease
Ulcerative colitis
High-volume, frequent watery stools usually are from the
Small intestine
small-volume stools with tenesmus, or diarrhea with mucus, pus, or blood occur in
Rectal inflammatory conditions
Diarrhea is common in this medication
penicillins and macrolides,
magnesiumbased antacids,
metformin, and
herbal and alternative medicines
constipation should be present for at least 12 weeks of the prior 6 months with at least two of the following conditions
fewer than 3 bowel movements per week;
25% or more defecations with either straining or sensation of incomplete evacuation;
lumpy or hard stools; or manual facilitation
occurs in an obstructing “apple-core” lesion of the sigmoid colon
Pencil like stool

Lower GI
More distally, the common bile duct and the pancreatic ducts empty into the duodenum at the
Ampulla of vater
Blood on the surface or toilet paper
Hemorrhoids
Mechanism of jaundice
Increased production of bilirubin
◗Decreased uptake of bilirubin by the hepatocytes
◗Decreased ability of the liver to conjugate bilirubin
◗Decreased excretion of bilirubin into the bile, resulting in absorption of conjugated bilirubin back into the blood
Disease that attributed to increased production of bilirubin
Hemolytic anemia
Unconjugated bilirubin diseases
Hemolytic anemia
Gilbert’s syndrome
Impaired excretion of conjugated bilirubin is seen in
Viral hepatitis
cir rhosis,
primary biliary cirrhosis,
drug-induced cholestasis
may obstruct the common bile duct
Gallstones
Pancreatic carcinoma
Extrahepatic jaundice arises from obstruction of the extrahepatic bile ducts, most commonly the
Cystic duct
Common bile duct
Intrahepatic
damage to the hepatocytes
Hepatocellular
Intrahepatic
from impaired excretion as a result of damaged hepatocytes or intrahepatic bile ducts
Cholestatic
not water-soluble, so it is not excreted into urine
Unconjugated bilirubin
indicates impaired excretion of bilirubin into the gastrointestinal tract
Dark urine from bilirubin
