Dysphagia Flashcards
What are some of the categories causes of dysphagia can be classified into?
Inflammatory
Neurological
Mechanical obstruction
What are some of the inflammatory causes of dysphagia?
Tonsillitis
Pharyngitis
Oesophagitis - can be due to GORD
What are some of the neurological causes of dysphagia?
Local - Bulbar palsy, Achalasia
Systemic - Systemic sclerosis (CREST), Myasthenia gravis
What are some of the things that may cause mechanical obstruction leading to dysphagia?
Luminal - Foreign body, large food bolus
Mural - Oesophagitis, trauma, pharyngeal pouch, malignancy
Extra-mural - Goitre, Rolling hiatus hernia, Lung Ca, Mediastinal lymph nodes, Thoracic aortic aneurysm
What investigations can be done in a patient with dysphagia?
Barium swallow
OGD
What is Achalasia?
Degeneration of myenteric plexus causing dysfunctional contraction of the oesophagus. Reduced peristalsis and lower oesophageal sphincter fails to relax
What causes Achalasia?
Mostly idiopathic
May be secondary to Chagas’ disease (Caused by bloodsucking bugs in South America, CNS/Heart effects)
How do patients with Achalasia usually present?
Progressive dysphagia from liquids to solids
Regurgitation especially at night
Weight loss
Substernal cramps
What are some of the complications of Achalasia?
If chronic, there is an increased risk of oesophageal SCC
What investigations can be done in a patient with suspected Achalasia?
Barium swallow - Bird beak (Dilated tapering oesophagus)
CXR - Widened mediastinum
OGD to exclude malignancy
What is the management of a patient with Achalasia?
Can give calcium channel blockers or nitrates
Can do endoscopic balloon dilatation
Surgery - Heller’s cardiomytotomy (Cut LOS to help relax muscle and allow food to pass through)
What is Diffuse oesophageal spasm?
Intermittent severe chest pain +/- dysphagia
Barium swallow shows a corkscrew oesophagus
Calcium channel blockers or PPIs can be used to treat
What is Nutcracker oesophagus?
Intermittent dysphagia +/- chest pain
Due to increased contraction pressure, but peristalsis is normal.
Give calcium channel blockers, PPIs, avoid triggers eg hot/cold drinks
What is a pharyngeal pouch?
Outpouching between crico- and thyro-pharyngeal
components of the inferior pharyngeal constrictor
Usually occurs posteriorly, but presents as swelling in left side of the neck
How does a pharyngeal pouch cause dysphagia?
Food debris trapped in pouch → pouch expansion → oesophageal compression → dysphagia
