Esophagus Flashcards
What is GERD?
reflux of stomach contents causing symptoms/complications
factors contributing to GERD
impaired LES function hiatal hernia irritant effect of refluxate abnormal esophageal clearance delayed gastric emptying (gastroparesis)
typical clinical features of GERD
asymptomatic
sour taste
water brash
retrosternal burning
atypical clinical features of GERD
asthma chronic cough laryngitis sore throat non-cardiac chest pain halitosis dental erosions yellow tongue chronic sinusitis
alarming clinical features of GERD
troublesome dysphagia odynophagia weight loss iron deficiency anemia persistent disease despite treatment
the classification system of severity of erosive esophagitis
Los Angeles grade A B C D
DDx of GERD (clinical and endoscopic)
clinical: motility disorders peptic ulcer angina functional dyspepsia
endoscopic:
pill induced
eosinophilic esophagitis
infections
medical treatment for mild/intermittent GERD:
lifestyle changes and meds on need (antacids / H2R blocker)
medical treatment for troublesome cases of GERD
PPI 1/day
if not controlled after 4 - 8 weeks, PPI 2/day
Long term S/Es of PPI
gastroenteritis pneumonia iron and B12 deficiency impaired calcium absorption -> hip fractures fundic gland polyps
gastric acid is antibacterial, thats why PPIs cause gastroenteritis and pneumonia
_ months PPI for those with typical reflux symptoms
3
what do u do with the 5% of GERD patients who don’t respond to PPI 2/day or change of agent?
endoscopy, look for other diagnosis
u do endoscopy for a patient with suspected GERD unresponsive to treatment. what can be seen?
residual esophagitis (low dose or not compliant)
truly not responding:
gastrinoma
pill induced
resistance to PPI
could also be normal
GERD not responsive to meds –> endoscopy
endoscopy normal –> ?
pH - impedance test
Treatment of functional GERD (everything seems normal)
tricyclic antidepressants (cuz its probably cuz of stress)
surgery for GERD
fundoplication
fundoplication offers good relief and healing of esophagitis in __% of properly selected patients
85
complications of fundoplication
recurrence (10 - 30 %)
new symptoms - dysphagia, bloating, dyspepsia, diarrhea (>30 %)
indications for fundoplication in GERD
- healthy patient w/ atypical symptoms
- severe GERD but don’t wanna take PPIs for the rest of their life
- large hiatal hernia
- persistent reflux despite PPI
complications of GERD
Barret esophagus
Peptic stricture
how does barret esophagus look?
orange gastric type epithelial tongue like projections into the esophagus
what percentage of chronic GERD results in barret esophagus?
10%
OGD goes down until where?
second part of duodenum
Barium swallow is pretty much useless in GERD (cuz mucosal damage doesn’t show on the x-ray), except in which case?
strictures
In barret’s esophagus, the metaplasia can be into gastric cardiac/fundic epithelium or specialized intestinal epithelium.
which one is premalignant?
specialized intestinal
symptoms of barret’s esophagus
no symptoms
does GERD treatment (PPI & anti-reflux surgery) cure Barret’s esophagus?
no, it just slows the progression
what cancer develops from barrett metaplasia?
adenocarcinoma
how often do u do surveillance in barret esophagus?
every 3 - 5 years
