Esophageal Function Testing

High-resolution esophageal manometry (open access)
normal
                achalasia
   

Ambulatory reflux monitoring

  • Traditional catheter-based pH (open access)
    • Typically performed while not taking acid-reducing medications
  • Bravo® capsule pH (requires clinic consultation prior)
    • Typically performed while not taking acid-reducing medications
  • Catheter-based intraluminal impedance/pH for detecting both acidic and non-acidic reflux (open access)
    • Typically performed while taking acid-reducing medications
   

Endolumenal Functional Lumen Imaging Probe (EndoFLIP)

This procedure requires a prior clinic consultation.

  • Performed in conjunction with an EGD, EndoFLIP uses impedance planimetry to measure distensibility of the esophageal wall and cross-sectional area of the esophageal lumen
  • Clinical indications include:
    • Suspected atypical achalasia
    • Dysphagia post-therapy for achalasia
    • Dysphagia post-fundoplication
