Q

t/f: Pancreatic cancer is typically dxed early when patients present with jaundice

A

false

The head of the pancreas is involved in 60% of cases. Because of it’s proximity to the CBD, patients often don’t present until they are jaundiced. It is often too late by that time and it has metastasized by then. The incidence of pancreatic cancer has tripled. 5% survival rate at 5 years.

40
Is jaundice an early or late symptom of cirrhosis?
late
41
t/f: pancreatitis Stimulates the exocrine function of the pancreas leading to overproduction of pancreatic enzymes.
false
42

prehepatic
43
Pre or intrahepatic or obstructive: liver can't conjugate or excrete
intrahepatic
44
cholangitis
inflammation of the common bile duct
45
When should colonoscopy vs. Cologuard be performed?
>45 years, colonoscopy every 10 years and higher risk, Cologuard for lower risk
46
Skin changes with liver disease
petiecchiae, ecchymosis, pruritis, spider angiomas, peripheral edema, jaundice
47
cholelithiasis
gallstones
48
t/f: Pancreatitis causes right upper quadrant pain associated with meals high in fat.
false, this is gallstones
49
Is there a chronic state of Hep A?
No. self limiting, usually not fatal. Usually highly symptomatic and body clears it.
50
DNA or RNA? Hep A, B, C
RNA: A, C DNA: B
51
Liver failure: low or high cholesterol
low
52
Most colon cancer arises from...
Polyps
53
Which type of obstruction requires a lysis of adhesions?
mechanical
54
Complications of bowel obstruction
perforation, peritonitis, fluid and electrolyte imbalance, acid/base disturbances, hypovolemic shock
55
Top 5 complications of ulcerative colitis
Hemorrhage, perforation, nutritional deficiency, colon cancer, toxic megacolon (also abscess, peritonitis, fistulas)
56
Pre or intrahepatic or obstructive: ^^ both conjugated and unconjugated bilirubin
intrahepatic
57
Diagnostic tools for obstruction
X ray and CT
58
How does liver failure cause encephalopathy?
Impaired conversion of ammonia to urea
59
process of Inflammation of the liver
inflammatory cells, edema (hepatomegaly), chronic --> necrosis
60
Pre or intrahepatic or obstructive: ^^ conjugated bilirubin
obstructive
61
What is HBsAg
The marker that you have Hep B
62

What benefit is there for testing stool for DNA over testing just for occult blood?
Stool DNA testing can pick up on precancerous DNA mutations which is superior to looking for hidden blood which is a symptom of colon cancer. The procedure is similar to occult blood testing as both take a sample of stool for testing. Both can be done at home and then sent into the lab.

75
t/f: Patients with cholecystitis always have gallstones
false Cholecystitis can be caused by gallstone or by "acalculous" where no stones are found. Acalculous cholecystits can be caused by trauma, DM, fasting, dehydration, opioid use, or hormone replacement therapy.
76
t/f: Pancreatitis can result in the release of pancreatitc enzymes into the peritoneal cavity or into the general circulation.
true
77

blood backs up in the portal vein (valveless) -- causes collateral circulation in GI tract, rectum, esophagus
