stomach disorders Flashcards
PUD, tumor, gastritis, diverticulitis, pyloric stenosis
what causes type A gastritis
involves what part of stomach
autoimmune disorders(pernicious anemia) and other non infectious factors
involves the body of the stomach
H pylori present in what ulcers
70% duodenal
up to 90% of peptic ulcers
relief with food, recurring in 2-4 hrs
PUD
epigastric pain turning to a radiating and constant pain
think perf or penetration from a PUD
meds for good mucosal defense
misoprotol, sulcralfate
H pylori eradication
combo therapy for 2-3 weeks:
1) PPI with [clarithomycin and amoxicillin] or [clarithomycin and addition of metronidazole] or
2) bismuth subsalicylate plus tetracycline, metronidazole, and PPI
prophylactic tx with misoprostol or a PPI: hx of ulcer who require a daily NSAID, hx of bleed, need for chr steroids or anticoagulants, signficant co morbidities
h pylori shape
implicated in what cases
gram neg, spiral shaped bacillus
almost all non NSAID induced GI mucosal inflammation
h pylori causes what
type B gastritis; involves the antrum and body of stomach
h pylori associated with what 3 diseases
why is in the stomach
it tolerates the acidity of the stomach;
peptic ulcer, gastric adenocarcinoma, and gastric lymphoma
NSAIDs and the stomach lining
it can cause gastric injury by diminishing local prostaglandin production in the stomach and duodenum.
.other causes of gastritis
alcohol, stress from CNS, burns, sepsis
.common indicators of gastritis
dyspepsia and abdominal pain n/v
dx tests for h pylori
2 for sure tests
2 maybe tests
initial: endoscopy with bx
urea breath test;
fecal antigen testing or serology is also helpful
nausea and feeling of excessive fullness after meals
delayed gastric emptying
tx: prokinetic meds
prokinetic meds
cisapride, metoclopramide
NSAID induced GI mucosal inflammation implicates what usually
h pylori
H pylori involves what part of the stomach
antrum and body which is type B gastritis
.gastric vs duodenal ulcers assoc with malignancy?
gastric
.gnawing or burning abdominal pain that often radiates to the back
PUD
also think ZES
.difference with pain between a duodenal ulcer and a gastric ulcer
duodenal pain improves with food. gastric worsens with food
.what is the most common cause of non hemorrhagic GI bleeds
PUD
.best test for PUD and why
upper endoscopy b/c its more sensitive and definitive
differeniates gastritis from ulcer disease;
all gastric ulcers need repeat endoscopy to document healing
.tx for PUD (h pylori +)
pepto with tetracycline, metronidazole, and PPI x 14 days
.PUD related to ZES?
1%
.what is PUD
any ulcer of the upper digestive system
h pylori found in what percentage of cancer pts
gender?
80%
male 3:1
.common cause of PUD
whats good about this
H pylori
the disease can be erradicated with treatment
.gastric ulcers and h pylori: association with gastric malignancy
although most patients with h pylori or a gastric ulcer will not get gastric cancer, almost all pts with gastric cancer have had h pylori or a gastric ulcer
.common cause of non hemorrhagic GI bleeds
PUD
.melena
PUD
dyspepsia symptoms
belching
bloating
distention
heartburn
think PUD, may have nausea and bleeding
.disadvantage of PUD tests:
barium radiography,
serum antibody test
stoot antigen testing,
urea breath test
barium radiography: cheap but less sensitive, 30% false neg rate
serum antibody test: highly sensitive but cannot be used to confirm cure
stoot antigen testing and urea breath test: s and s but not accurate for 4 weeks after completion of treatment
how much of gastrinomas are part of multiple endocrine neoplasia(autosomal dominant condition)
one third
what fasting gastrin level indicates hypergastrinemia
> 150
.what test diagnoses ZES
what tests to localize the tumor
secretin: givin 2 units, gastrin levels will increase by more than 200
endoscopy, CT, MRI
.tx of ZES
PPI or sx
