Barrett's Oesophagus Flashcards

1
Q

def

A

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

Q

aetiology

A

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

Q

epi

A
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

Q

management

A
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

Q

complications

A
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

Q

prognosis

A

adenocarcinomas found while screening for barrett’s oesophagus are early lesions and have a good prognosis (>85% 5yr survival)
