­­

Causes of dysphagia

  • Intraluminal:
    • Foreign body
    • Poylpoid tumour
  • Intramural:
    • Benign stricture
      • GORD, caustic, radiotherapy
    • Malignant stricture
    • Tumour
    • Oesophagitis
    • Oesophageal spasm
    • Scleroderma
    • Pharyngeal pouch
    • Plummer-Vinson web
    • Schatzki ring
    • Achalasia (failure of lower of oesophageal sphincter relaxation)
  • Extra-mural:
    • Lymph nodes
    • Rolling hiatus hernia
    • Retrosternal goitre
    • Bronchial carcinoma
    • Thoracic aortic aneurysm
    • Enlarged left atrium
  • Systemic:
    • Myasthenia gravis
    • Stroke/TIAs
    • Bulbar/pseudobulbar palsy
    • Syringobulbia
    • Parkinson’s
    • Bulbar polio

 

 History in dysphagia

  • Presenting complaint
    • Difficulty in swallowing
  • History of presenting complaint
    • Onset
    • Progression
      • Gradual and progressive or intermittent (spasm or achalasia)
    • Solids/Liquids/Both
      • And was there dysphagia to both right from the start?
    • Odynophagia (pain on swallowing – cancer, oesophagitis or spasm)
    • Is initiation of swallowing difficult
      • Think bulbar palsy
    • Associated reflux/water brash symptoms
    • Regurgitation of food
    • Level where the food sticks
    • Constitutional symptoms
      • Weight loss, night sweats, anorexia
  • Past medical history
    • Gastrointestinal surgery
    • Barrett’s oesophagus (premalignant condition for oesophageal carcinoma)
    • Neuromuscular disease
    • Hypertension
    • Cardiovascular disease
    • Rheumatological disease
  • Medications
    • Bisphosphonates
    • NSAIDs
    • Steroids
  • Allergies
  • Family history
    • Oesophageal carcinoma
  • Social history
    • Alcohol consumption
    • Smoking

 

 Examination in dysphagia

  • Anaemia
  • Lymphadenopathy
  • Cachexia
  • Jaundice/Hepatomegaly – potential liver metastases
  • Scleroderma

 

 Initial investigations in dysphagia

  • Blood tests:
    • Full blood count and haematinics
    • Urea and electrolytes
    • Liver function tests
  • Chest x-ray
  • Upper GI endoscopy (plus biopsy)
  • Barium swallow

 

 Further management of dysphagia will depend on the cause but can include:

  • Oesophagectomy (for early stage carcinoma)
  • Endoscopic dilatation for strictures
  • Antibiotic/antifungals for oesophagitis
  • Oesophageal manometry testing for achalasia
  • Treatment of any underlying systemic condition
