Barrett's Oesophagus Flashcards
def
change in normal squamous epithelium of the oesophagus to specialised intestinal metaplasia
associated with GORD
associated with increased risk of adenocarcinoma of the oesophagus
for diagnosis, biopsy showing columnar-lined epithelium, with or without intestinal metaplasia and with goblet cells
aetiology
primary aetiological factor is GORD
acid & bile reflux causes oesophageal mucosal injury
overtime may cause normal squamous epithelium to change into columnar lined epithelium with or without intestinal metaplasia & with goblet cells
epi
increasing incidence around 1-2% of the general population frequency of oesophageal adenocarcinoma has increased, this may be linked to increased incidence of GORD increases with age more common in caucasian males
risk factors
GORD
increased age
white males
history & examination
presence of risk factors (GORD, increased age, white males) heartburn (symptom of GORD) regurgitation (symptom of GORD) dysphagia chest pain (atypical GORD symptom)
investigations
1 upper GI contrast radiography
-hiatal hernia & reflux
2 upper GI endoscopy with biopsy
-abnormal epithelium characteristic of Barrett’s oesophagus
management
if no evidence of dysplasia: -regular endoscopic surveillance for high grade dysplasia: -oesophagectomy -endoscopic treatments such as endoscopic mucosal resection or ablation
NSAIDS such as aspirin have been shown to prevent oesophageal cancer in people with barrett’s oesophagus
complications
1 reduce QOL -oesophageal-related symptoms -depression, anxiety, stress 2 oesophageal stricture -due to the acid reflux 3 adenocarcinoma -average interval between cancer & barrett's oesophagus is 4yrs -incidence is 0.25-0.5% per year
prognosis
adenocarcinomas found while screening for barrett’s oesophagus are early lesions and have a good prognosis (>85% 5yr survival)
