GI - PowerPoint/6 Flashcards
abdominal distention and decreased bowel sounds are sx of
acute pancreatitis
chronic pancreatitis pain
continuous or intermittent abdominal pain and weight loss
acute pancreatitis causes activation of
pancreatic enzymes inside the pancreatic ducts
acute pancreatitis may result from
3
- direct cell injury from alcohol, drugs, or viral infection
acute pancreatitis sx of chock are caused by
hypovolemia
acute pancreatitis precipitating factors are
4
- alcohol consumption
- biliary tract obstruction
- cancer
- mumps virus
pancreatitis - substances released by necrotic tissue lead to
widespread inflammation
risk factor for pancreatic cancer
chronic pancreatitis
colorectal cancer sx in early stages
silent
colorectal cancer - caused by mulitple gene alterations and environmental interactions
2
- familial adenomatous polyposis
2. hereditary nonpolyposis
acute pancreatitis tx
3
- oral intake is stopped
- tx of chock and electrolyte imbalances
- analgesics for pain relief
FIT test is to
stool based test for colorectal cancer
colorectal cancer screening - stool based test types
2
- guaiac test
2. fecal immunochemical test FIT
acute pancreatitis low grade fever until
infection develops
acute pancreatitis - abdominal distention and decreased bowel sounds are caused by
2
- decreased peristalsis
2. paralytic ileus
BRAF
tumor marker - tumor tissue for colorectal cancer
pancreatitis
inflammation resulting in autodigestion of the tissue
pancreatitis - substances released by necrotic tissue lead to widespread inflammation and what may follow
2
- hypovolemia
2. circulatory collapse
most colorectal cancers are located where
ascending colon 25%
chronic pancreatitis is related to
chronic alcohol abuse
possible complications of acute pancreatitis
2
- adult respiratory distress syndrome ARDS
2. acute renal failure
acute pancreatitis can be caused by
4
- gallstones
- alcohol abuse
- intake of large meal
- intake of large amount of alcohol
primary sx of acute pancreatitis
severe epigastric or abdominal pain radiating to the back
colorectal cancer screening tests
2
- stool based
2. visual based
acute pancreatitis - what may result
septicemia
acute pancreatitis dx tests include
4
- serum amylase levels
- serum lipid levels
- hypocalcemia
- leukocytosis
colorectal cancer polyps
2
- colorectal polyps
2. neoplastic polyps
acute pancreatitis sx include
5
- severe epigastric pain
- severe abdominal pain radiating to the back
- low grade fever
- abdominal distention
- decreased bowel sounds
septicemia is to which pancreatitis
acute
colorectal cancer tumor tissue markers include
2
- K-RAS
2. BRAF
K-RAS is to
tumor marker - tumor tissue for colorectal cancer
carcinoembryonic antigen CEA is to
tumor marker in blood for colorectal cancer
acute pancreatitis
chemical peritonitis results in bacterial peritonitis
colorectal cancer tumor markers include (main categories)
- blood
2. tumor tissue
pancreatitis may progress to
surrounding tissue/organ
pancreatitis obstruction
obstruction to the outflow of pancreatic digestive enzymes caused by bile and pancreatic duct obstruction
acute pancreatitis dx test - serum amylase levels
first rise, then fall after 48 hours
inflammation resulting in autodigestion of the tissue
pancreatitis
chemical peritonitis results in bacterial peritonitis
acute pancreatitis
colorectal cancer screening test - visual based
2
- CT scan
2. colonoscopy
chronic pancreatitis is the process of
progressive fibrotic destruction of the pancreas
severe epigastric or abdominal pain radiating to the back
primary sx of acute pancreatitis
acute pancreatitis serum lipid levels are
elevated
process of progressive fibrotic destruction of the pancreas
chronic pancreatitis
CA 19-9 is to
tumor marker in blood for colorectal cancer
acute pancreatitis dx test of choice
serum amylase levels
colorectal cancer screening ages
- 45 yrs - recommended
2. 50 years - strong recommendation
which form of pancreatitis is considered a medical emergency
acute
colorectal cancer sx depend on
3
location
size
shape
guaiac test is to
stool based test for colorectal cancer
colon and rectum cancer - most are
sporadic or associated with a family hx of colorectal cancer
colorectal cancer blood tumor markers
2
- carcinoembryonic antigen CEA
2. CA 19-9
pancreatitis that is usually mild and resolves spontaneously
acute
acute pancreatitis cardinal manifestation is
epigastric or midabdominal constant pain
ARDS and acute renal failure are possible complications of
acute pancreatitis
acute pancreatitis - body temp may rise significantly when
infection develops
