4. GERD, PUD, And Related Disorders Flashcards
What are the 3 main parts of the mucosal defense system?
Mucous Gel Layer
Surface epithelial cells
Subepithelial elements
Composition of mucous gel layer
95% water and 5% mucin
Which part of the mucosal defense system serves as a barrier protection?
Mucous gel layer
Which part of the mucosal defense system provides cell protection and regeneration?
Subepithelial elements
Which part of the mucosal defense system produces mucus and regulates pH, and produces protective heat shock proteins that prevent protein desaturation?
Surface epithelial cells
Considered the “housekeeping elements”.
COX-1
Exacerbating factors of GERD regardless of causative factor.
Abdominal obesity Pregnancy Gastric hypersecretory states Delayed gastric emptying Disruption of esophageal peristalsis Gluttony
Excessive reflux of gastric contents back through the LES
GERD
The TWO most common GERD Sx. “Hallmark”
HEARTBURN and REGURGITATION
Less common GERD Sx.
Dysphagia
Chest Pain
“The great imitator”
Biliary colic
Pain associated with a bad gallbladder, can present in many ways.
Biliary colic
The DOMINANT clinical strategy for GERD
Lifestyle modifications + Empirical Tx with acid inhibitors
How long should you try the initial tx for GERD before checking on symptomatology?
8-12 wks
What are important exceptions to the GENERAL approach to tx for GERD?
PERSISTANT DYSPHAGIA or CHEST PAIN
What foods reduce LES pressure?
Fatty foods ETOH Spearmint/Peppermint Tomato-based foods Coffee/tea
Does reducing the acidity of gastric juice prevent reflux?
No, just decreases sx and allows esophagitis to heal
The most effect GERD med
PPI
What PPI do you generally start with for GERD tx?
Omeprazole (20 mg QDay x 8-12 weeks)
When should pt’s take Omeprazole (PPI’s)?
30 min BEFORE FIRST MEAL
What pt’s may need longer term PPI use?
Sx return after discontinuance of PPI
Erosive disease
Barrett’s esophagus
What is a maintenance option for pt’s without erosive disease or Barrett’s esophagus (if effective)?
H2 blockers
