SG Esophagus Flashcards
3 possible causes of GERD
- Inappropriate transient lower esophageal relaxations
- Floppy LES
- Hiatal hernia
Why do GERD pts get dysphagia?
Inflammation // erosive esophagitis
Ineffective esophageal motility
Less likely: peptic stricture, cancer
Study for:
- Dysphagia
- Eval esophageal mucosa
Barium CXR
Endoscopy
Mechanical or motor: dysphagia to solids and liquids
MOTOR
Motor problem w/ dysphagia - what is the disease
Achalasia
- Dysphagia
- Regurg
Achalasia patho
Lose inhibitory motor neurons in LES and neuronal drop out in body of esophagus
Net: hypertensive LES + aperistalsis body of esophagus
Barium swallow results for achalasia
Bird’s beak w/ dilated esophagus behind it`
Why perform endoscopy for achalasia
R/o pseudoachalasia
Small, infiltrating distal esophageal cancer or proximal gastric cancer can infiltrate the neuronal plexus of the LES
Mimics achalasia
3 ways to treat achalasia
- Smooth muscle relaxants - Ca CB
- BoTox injection into LES
- Balloon dilation or cut LES
Treat nutcracker esophagus
- Reassurance
- SM relaxants - dysmotility
- Pyschotropic agents - hypersensitivity
Cancer vs peptic stricture on barium swallow
Cancer = irregular narrowing Peptic = smooth, tapered narrowing of distal esophagus
