Oesophageal Disease Flashcards
Acute oesophagitis is more common than chronic oesophagitis. True/False?
False
What are some causes of acute oesophagitis?
Chemical abuse -> corrosion
Infection (herpes, candidiasis)
What is the main cause of chronic oesophagitis?
Reflux disease [reflux oesophagitis]
Define “reflux oesophagitis” (GORD)
Inflammation of the oesophagus due to reflux of acid from the stomach
What are the 3 main causes of GORD?
Incompetent LOS
Poor oesophageal motility/clearance
Impaired mucosal barrier
What is the dominant immune cell that accompanies acid abuse?
Eosinophils
Name 3 complications of reflux oesophagitis
Ulceration/bleeding
Stricture formation due to scarring
Barrett’s Oesophagus
Define “Barrett’s Oesophagus”
Replacement of stratified squamous epithelium -> columnar epithelium [metaplastic change]
How is Barrett’s Oesophagus pre-malignant?
Mucosa becomes unstable, and persistent acid insult increases risk of developing dysplasia and carcinoma
What is allergic oesophagitis?
Immune-mediated oesophagitis caused by reaction to food
Eosinophilic infiltrates present
Benign oesophageal tumours are rarer than malignant tumours. True/False?
True
What is the most common benign oesophageal tumour?
Squamous papilloma
What are the two main types of malignant oesophageal tumour?
Squamous cell carcinoma
Adenocarcinoma
Squamous cell carcinoma of oesophagus is commoner in males. True/False?
True
Where is adenocarcinoma of the oesophagus most likely to develop? Why?
Lower 1/3 of oesophagus
Reflux insult is greatest here
