GI - 4 Stomach pt 1 Flashcards
List 4 causes of Erosive and Hemorrhagic Gastritis
Drugs (NSAIDS)
Etoh (alcohol)
Stress (illness)
Portal hypertension
What are the Symptoms of Erosive and Hemorrhagic Gastritis?
None or some: Dyspepsia Epigastric pain Nausea and vomiting UGI bleed
Endoscopy finds superficial lesions, subepithelial hemorrhages, petachiae (purple spot), and erosions
Erosive and Hemorrhagic Gastritis
If there were any abnormal lab results for Hemorrhagic Gastritis what would they be?
Iron deficiency anemia
Stress Gastritis is a specific cause of:
Erosive and Hemorrhagic Gastritis
Tell me about Stress Gastritis (how it develops, how to cure it, treat it)
Develops within 72 hours of critical illness
To cure it we want a gastric pH > 4
We do so using PPI or H2 blockers (prophylaxis)
Treat using high dose PPI
What are 5 alarm symptoms of Gastritis? What do yo do?
Severe pain, wt loss, vomiting, GI bleed, anemia
Do Endoscopy
Congestion of capillaries and venules of gastric mucosa and submucosa. Has to do with serosis, portal hypertension, ability to drain to portal system. Correlates with liver disease. Appear to be chronic asymptomatic bleeders
Portal Hypertensive Gastropathy
Tell me 3 things about Portal Hypertensive Gastropathy. What’s the treatment? (2)
Congestion of capillaries and venules of gastric mucosa and submucosa
Correlates with severity of liver ds
Often asymptomatic but may present as chronic bleed
Tx: Propanolol or nadolol to lower portal pressure and prevent rebleeding or portal decompressive procedures
What are the 3 categories of Nonerosive Nonspecific Gastritis
H pylori infection
Pernicious Anemia
Lymphocytic Gastritis
Tell me 4 things about H. Pylori Gastritis
Spiral gram negative rod
Resides below gastric mucus layer adjacent to gastric epithelial cells
Causes gastric mucosal inflammation with PMNs and lymphocytes
Increased in nonwhites and immigrants
List 3 complications of H Pylori
15%develop PUD
Increased rate of gastric adenocarcinoma
Increased rate of low grade B cell gastric lymphoma
4 groups tested for H pylori
H/o PUD (peptic ulcer disease)
H/o mucosa associated lymphoid tissue lymphoma (maltoma)
Family history of gastric CA especially if of Asian descent
Screening isn’t indicated in general population
List 3 tests to diagnose H pylori Gastritis
Which is gold standard?
2 noninvasive tests:
Serologic tests sensitive but not specific (not recommended for eradication)
Fecal antigen tests and Urea breath tests > 95% sensitive and specific
1 Invasive test:
Endoscopy with bx of antrum and body is gold standard but expensive
Why do you biopsy the antrum to test for H pylori?
Bacteria tends to settle in the antrum
