The advantage of this procedure is that it allows the physician a quick "look-see" without sedation, and it is probably cheaper because it doesn't require anesthesia. The doctor can visually check for Barrett's, and be done in a few minutes.
The disadvantage is that, in terms of diagnosing reflux, it doesn't really get you anywhere if you have NERD, or non-erosive reflux disease. There is basically nothing to see. The best tool for nailing down a diagnosis is the 48-hour Bravo pH study, which requires a traditional endoscopy to implant the transmitter. Also, a traditional endoscopy allows for biopsies (like eosinophil counts).
"Swallowing therapy?" If your dysphagia is caused by reflux, no amount of physical therapy will correct the condition as long as reflux is present.
