Esophagus


DYSPHAGIA: 3 questions needs to be defined: 
  • Location of Dysphagia
    • Orophyrangeal or 
    • Esophageal; 
  • If Esophageal mechanism of dysphagia- 
    • Mechnical (only solid) or 
    • Motor (Both Solid and/or Liquid) - 
  • Then characteristics of dysphagia
    • progressive or 
    • intermittent or non-progressive

    • Clinical Pearls:
      • PPI should preferably be given before the first meal of the day ( when H-K-ATPase present in parietal cell is greatest after a prolonged fast, and parietal cells are stimulated post-prandially to secrete acid)
      • PPI should not be given with other acid suppresants.
      • PPI can be given twice a day (before evening meal) if needed and is useful especially in the first few days
      • PPI has its maximum effect (around 65%) after 5 days; normal acid secretion is restored after 24 - 48 hr 
      • H2B work best for PRN (due to rapid onset action) ; PPI are not good for PRN dosing

  • Esophgeal 
    • EGD vs Barium Swallow (can stick and coat) 
      • Hence, Barium Swallow is avoided if suspecting food impaction

      • Achalasia 
        • 3 types 
            • Type 1 :No motility at all, no relaxation of EGJ 
            • Type 2: Pressure generation is there, but Absent peristalsis, no relaxation of EGJ 
              • Best prognosis
            • Type 3: Spastic achalasia, no relaxation of EGJ
              • Worst prognosis
