Esophagus Flashcards
Substernal burning sensation
often radiates to the neck
Pyrosis (heartburn)
Highly specific for GERD
Difficulty swallowing?
PAINFUL swallowing?
Dysphagia
Odynophagia
Characterirized by immediate sense of bolus catching in the NECK
Need to swallow repeatedly to clear food from pharynx
Or coughing/chocking
Pharyngeal (oropharyngeal)
Pharyngeal = prompt
Esophageal dysphagia can be caused, broadly, by what?
Mechicanical obstruction (solids)
Motility disorders (more severe: solids and liquids)
Study of choice for evaluating heartburn, dysphagia, odynopahgia, structura abnormalities?
Upper endoscopy
In patients w/ suspected motility disorders (of the esophagus) what study should be performed first?
Barium swallow
barium esophagography
Mechanical causes of esophageal dysphagia…
Schatzki ring
Stricture (Peptic)
Eisonophilic esophagitis
Cancer (Esophageal )
Motility-related causes of esophageal dysphagia
Achalasia
ineffective esophageal motility (duh)
Diffuse esophageal spasm
Scleroderma
Tests function of LES?
esophageal manometry
A diagnostic study option for esophageal dysphagia but only provides info for acid reflux (no nonacid data provided)
pH testing
GERD…
- Heartburn. May be exacerbated by meals, bending, or ____?
- Typical uncomplicated cases do not require _____.
- Endoscopy demonstrates abnormalities in ____ of patients
- recumbency.
- diagnostic studies.
- one-third (so, MOST patients will NOT have abnormalities)
two most common symptoms of GERD?
heartburn and regurgitation
Etiologies of GERD?
- Dysfunction of the LES (usually due to transient relaxations of LES caused by gastric distention)
- Hiatal hernias
- Abnormal esophageal clearance
- Delayed gastric empyting (gastroparesis or obstruction)
Damage to the mucosa of the esophagus due to acidity of refluxate… gastric fluid is what pH?
4.0, which is caustic to the esophageal mucosal surface
prolonged exposure -> dysplasia
Number one symptom of GERD? When’s it appear?
Heartburn… 30-60 min pc
Or upon reclining
(relieved w/ antacids)
GERD pts also typically present w/ waterbrash
regurgitation of sour fluid or almost tasteless saliva into the mouth
GERD is one of the top three causes of?
Chronic cough
less common ssx associated w/ GERDth
Cough Dysphagia (Suggest advacned dz) Laryngitis Sore throat Chest pn Difficulty w/ sleep (pts might angle their beds)
NOTE: in the absence of heartburn, these atypical unlikley to be related to GERD!!!
Physical exam for GERD is unremarkable… but what should be in your differential diagnosis?
Esophageal motility d/o Peptic ulcer ANGINA PECTORIS functional d/o Eosinophilic esophagitis
Initially no work up for GERD is warranted unless patient presents w/ alarm freatures, which are?
Fever/chills/ns
Wt. loss
Odynophagia
Dysphagia
OR patient who doesn’t respond to (h2, PPI therapy)
They get an EGD
GERD Pt w/ alarm features OR pts who don’t respond to therapy will get an EGD.
However, a specialist may also order what?
EGD = test of choice
But also consider esophageal pH or LES manometry
Barrett’s Esophagitis (15% of pts w/ GERD)… what happens to the esophageal tissue?
(GERD complication)
Normal squamous epithelium of esophagus is replaced by metaplastic columnar epithelium containing goblet and columnar cells
Development of Barret esophagus may affect ssx of GERD in what way?
Development may actuallY REDUCE ssx
Barrett esophagus increases risk for what?
esophageal adenocarcinoma
A less common (5%) complication of GERD? Presents how?
How might we treat this complication?
Peptic stricture… presetned w/ progressive food dysphagia
(can also result in reduction in heartburn as stricture acts as barrier)
(tx is endoscopic dilation)
What is a tx for ALL patients w/ GERD?
Lifestyle modifications
Smaller meals, avoidance of acidic foods or those that precipitate reflux and discontinue tobacco use
GERD Lifestyle modificatins in regards to sleep?
Avoid lying down for 3 hours after meals
Elevate the head of the bed
(also, consider wt loss)
Infrequent heartburn (less than once weekly) can be treated w/ what (in addition to lifetsyle mods)
OTC antacids (tums, rolaids, etc.) [provide rapid relief but short duration]
H2 receptor antagonists (-tidines)
Compare antacids w/ H2 receptor antagonists
OTC antacids (quick relief/short duration; contain Mg so caution in pts w/ kidney problems)
H2 receptor antagonists (onset is 30 mins, but provide 8 hrs relief)
