As a surgeon, you may find the tests listed below useful in managing and diagnosing GERD before or after surgery, dysphagia suspected to be esophageal in origin or even anorectal function before or after surgery. Our testing capability has improved dramatically and patients can now be studied on or off acid suppressive medications and with or without nasal catheters.
- Impedance-pH monitoring (on acid suppressive medications) can demonstrate non-acid reflux.
- Catheter free pH monitoring (BRAVO) can demonstrate the degree and quantity of esophageal reflux in a 48 hour period without the discomfort of a catheter placed in the nose.
- Ambulatory pH monitoring can demonstrate the degree of reflux in multiple locations in the esophagus using a nasal catheter placed for a 24 hour period.
- High resolution esophageal manometry will reveal esophageal motility disorders such as achalasia or impaired esophageal clearance.
- High resolution anorectal manometry can diagnose Hirschprung’s disease and neuromuscular function important for continence.
- Gastroduodenal manometry (small bowel motility) can suggest a neuropathic or myopathic cause for intestinal pseudo obstruction.
