Barrett's Oesophagus Flashcards
Define Barrett’s oesophagus
Metaplastic change arising in the lower oesophageal mucosa from oesophageal (stratified
squamous) epithelium to intestinal (simple columnar) epithelium secondary to prolonged
acid reflux
What are the causes/risk factors of Barrett’s oesophagus?
Caused by GORD • Central obesity • Age • White ethnicity • Male • Family history • Smoking
What are the signs and symptoms of Barrett’s esophagus?
Symptoms
• Heartburn
• Regurgitation
• Dysphagia
Signs
Nil of note
What investigations are carried out for Barrett’s oesophagus?
Endoscopy with biopsy:
• OGD
• histological specimen must be obtained. Barrett’s Oesophagus is a pathological diagnosis.
• The endoscopic appearance of Barrett’s oesophagus is violaceous epithelium proximal to the gastro-oesophageal junction. The Z line is migrated cephalad.
What is the management for Barrett’s oesophagus?
Conservative
• Smoking cessation
• weight loss
• low-fat foods
Non-dysplastic Barrett’s Oesophagus:
• PPI e.g. omeprazole, 20 mg/day P.O
• Endoscopic Radiofrequency Ablation –RFA
• Surveillance every 2 years, with biopsies of each of the 4 quadrants of the CLO
Barrett’s Oesophagus with Low-Grade Dysplasia: these are usually flat and non-nodular macroscopically
• High-dose PPIs
• Radiofrequency Ablation
• Endoscopic Mucosal Resection: If nodular lesions are present (but LGD)
• Surveillance within 6 months
Barrett’s Oesophagus with High-Grade Dysplasia: these are often nodular macroscopically
• High-dose PPIs
• Radiofrequency Ablation
• Endoscopic Mucosal Resection: If nodular lesions are present –allows for more accurate histology
• Surveillance within 3 months
• Oesophagectomy: a definitive treatment option, which enables identification of any occult malignancy.
What are the complications of Barrett’s oesophagus?
- Dysplasia
- Adenocarcinoma
- Oesophageal Carcinoma
- Oesophageal Stricture
