GI Flashcards
what increases risk of incarcerated hernia
smaller hernia- more likely to incarcerate
where is an indirect hernia located
lateral to interior epigastric artery
what decreases bulge in direct hernia
laying flat
patients most prone to femoral hernia
elderly female
exocrine function of pancreas is mediated by
acinar cells
which pancreas cells produce insulin
beta cells
pancreas cells that produce glucagon
alpha cells
MCC pancreatitis
gallstones >alcohol
usual site of rupture in boerhaves
distal left posterolateral wall of esophagus
diagnostic study of choice for boerhaves
esophogram using water soluble contrast
lower chest pain, vomiting, subq emphysema in boerhaves
mackler triad
management after rectal foreign body removal
observe 4-6 hours for signs of perforation
MCC pancreatitis worldwide
gallstones
MCC intermittent dysphagia with solids
Schatzki ring
how to diagnose achalasia
esophageal manometry (inc LES pressure)
thin structures in the esophagus associated with iron deficiency and plummer vinson
esophageal webs
vitamin deficiency that should be considered in neuro deficits + gastric bypass
thiamine deficiency
what lab value may be elevated in GI bleed
BUN
pain of duodenal ulcer
improves when eating (DUDe give me food)
what small bowel diameter suggests SB dilation
> 3cm
most common bacteria to cause cholangitis
E. coli, Klebsiella, Enterococcus, Bacteroides
LFTS in alcoholic hepatitis
2-10 times normal
what causes elevations in unconjugated bilirubin
unable to be excreted in bile and occurs after hemolysis and liver disease
most common cause of upper GI bleeding
PUD
indications for endoscopy in PUD
age >55, early satiety, dysphagia, persistent vomiting, anemia or GI bleed, jaundice, unexplaind weight loss, presence of abdominal mass
malignancy associated with h pylori
MALToma
what is the most common cause of acute mesenteric ischemia
cardiac emboli to SMA
migratory thrombophlebitis associated with pancreatic cancer

what is obstipation
inability to pass stool or flatus for more than 8 hours despite a perceived need
lateral anal fissures are associated with what conditions
IBD, malignancy, communicable diseases
within how many hours should NAC be given after tylenol ingestion to prevent hepatotoxicity
8 hours
distinguish between 2nd and 3rd degree internal hemorrhoid
2nd- protrudes but reduces on its own
3rd- protrudes and has to be manually reduced
medication that puts people at risk for mesenteric ischemia
digoxin
Fish with peppery taste
Scombroid
Rice water stools
Vibrio cholerae
Treatmnet of ETEC
Cipro/azithro
Contrast to find boerhaves
Water soluble
MC location of boerhave
left posterolateral distal esophagus
MC site of volvulus
sigmoid
Bilirubin that accumulates with increased production and decreased conjugation
Unconjugated, indirect
Accumulates in disease that slow secretion of bile into the intestine
Conjugated, direct
Compare exam for direct vs indirect hernia
Indirect goes into scrotum, direct does not
