aka Functional Luminal Imaging Probe (FLIP)

aka Endoscopic esophageal topography, (eg EndoFLIP)

• often done before and after procedure to assess improvement

To Study

Indications

• Achalasia

Assessment

• What is Normal?
• Assesses EGJ opening AND Contractile Response
  • normal = EGJ opens well, and normal peristalsis
• Measures
  • distensibility:
    • concept: looking at esophageal compliance
      • identify stricture, EGJ tightness

    • 3 is normal

  • diameter
  • planimetry
  • Volume
• Possible Results

Procedure

• usually 16cm balloon to assess esophagus
• some people use 8cm balloon to just assess EGJ
• 50-60cc distension
