9. Diagnostics
   1. Upper Endoscopy (EGD)
      1. First-Line study, indicated for red flag symptoms or symptoms refractory to empiric management
      2. Evaluates for obstructive lesions, structural deformities, inflammation and infection
      3. Allows for esophageal dilation in case of Esophageal Stricture
10. Imaging
    1. Contrast Esophogram
       1. May be considered in the acute evaluation for structural abnormalities of the esophagus
       2. Emergency department patient may be given Oral Contrast 60-120 ml (2-4 oz) immediately before upright XRay
          1. Allows for informal esophagram when radiologist is not available
    2. CT Chest
       1. Consider in the evaluation of chest mass suspected in esophageal obstruction
11. Management
    1. Expedited assesmment if red flags present (see above)
    2. Initial empiric management if no red flags
       1. See Gastroesophageal Reflux for general management
       2. Proton Pump Inhibitor trial for 4 weeks, and continue for 8-12 weeks if effective or confirmed diagnosis
    3. Manage specific causes based on diagnostics and differential diagnosis
       1. Gastroenterology Consultation
       2. Consider Esophageal Dysmotility in refractory cases (but avoid over diagnosis)
    4. Other measures for functional esophageal disorders
       1. See Esophageal Dysmotility for general measures that may be effective in Esophageal Dysphagia
       2. Avoid Opioids (worsens esophageal motility)
       3. Prevent Pill Esophagitis
