oesophagus Flashcards
main symptoms involving the oesophagus
dysphasia (deficiency in speech generation)
odynophagia (pain swallowing)
heart burn

oesophagitis
inflammation of the oesophagus due to reflux
oesophagitis acute:
rare, corrosive following chemical ingestion
oesophagitis chronic

reflux, defective sphincter (hiatus hernia) pregnancy (inc. intraabdominal pressure)
allergic oesophagitis incidence
male > female
allergic oesophagitis risk factor
history or family history of asthma
allergic oesophagitis histology
eosinophils, corrugated or spotty oesophagus
allergic oesophagitis treatment
steroids
chromoglycate
montelukast
barretts oesphagus
Metaplastic change where stratified squamous epithelium is replaced by columnar epithelium.
- Normally the squamous mucosa of the oesophagus and the columnar mucosa of the stomach meet at the Z line
barretts symptoms
largely as GORD but can be asymptomatic
barretts macroscopic appearance
red velvety mucosa in lower oesophagus
barretts complications
adenocarcinoma - this is a pre-malignant condition
barretts investigations
endoscopy shows epithelium change
biopsy to screen for cancer
barretts treatment
PPI and surveillance
