Barrett's Oesophagus Flashcards

1
Q

What is Barrett’s oesophagus?

A

Barrett’s oesophagus is a condition where there is an abnormal change in the cells lining the lower portion of the oesophagus due to chronic damage from gastro-oesophageal reflux disease (GORD).

Q

What are common symptoms associated with Barrett’s oesophagus?

A

Often asymptomatic, but may include heartburn, regurgitation, dysphagia, haematemesis, odynophagia, chest pain, and cough.

Q

How is Barrett’s oesophagus diagnosed?

A

Through upper gastrointestinal endoscopy with biopsy, identifying ‘salmon-coloured’ epithelium above the gastro-oesophageal junction.

Q

What is the recommended management for high-grade dysplasia in Barrett’s oesophagus?

Q

How often should surveillance endoscopy be performed for Barrett’s oesophagus without dysplasia?

A

Every 3-5 years if the segment is less than 3 cm with intestinal metaplasia; every 2-3 years if the segment is greater than 3 cm.

Q

What lifestyle modifications can help manage Barrett’s oesophagus?

A

Weight loss, elevating the head of the bed, avoiding meals before bedtime, and reducing intake of alcohol, caffeine, and fatty foods.

Q

What is the role of anti-reflux surgery in Barrett’s oesophagus?

16
Q

What histological finding confirms the diagnosis of Barrett’s oesophagus?

A

The presence of intestinal metaplasia with goblet cells in oesophageal biopsies.

17
Q

What is the significance of ‘salmon-coloured’ mucosa seen during endoscopy?

A

It indicates the presence of columnar-lined oesophagus, suggestive of Barrett’s oesophagus.

18
Q

What are potential complications of Barrett’s oesophagus besides adenocarcinoma?

A

Oesophageal strictures and ulcers.

19
Q

How does obesity contribute to the development of Barrett’s oesophagus?

A

Increased intra-abdominal pressure promotes gastro-oesophageal reflux, leading to chronic oesophageal damage.

20
Q

Why is male sex considered a risk factor for Barrett’s oesophagus?

A

Men have a higher prevalence of Barrett’s oesophagus and a greater risk of progression to oesophageal adenocarcinoma.

21
Q

What is the purpose of surveillance in patients with Barrett’s oesophagus?

A

To detect dysplasia or early cancer, allowing for timely intervention.

22
Q

How does smoking influence the risk of Barrett’s oesophagus?

A

Smoking increases the risk of progression from Barrett’s oesophagus to oesophageal adenocarcinoma.

23
Q

What is the typical appearance of Barrett’s oesophagus on endoscopy?

A

A visible segment of ‘salmon-coloured’ mucosa extending above the gastro-oesophageal junction.

24
Q

What is the recommended follow-up for patients with Barrett’s oesophagus and confirmed low-grade dysplasia?

A

Consider endoscopic ablation therapy or increased surveillance frequency, typically every 6-12 months.

25
Q

How does chronic gastro-oesophageal reflux lead to Barrett’s oesophagus?

A

Persistent acid exposure causes metaplasia, replacing squamous epithelium with columnar epithelium.
