New reflux technology is easier on the patient

Reported by Susan Aldridge, PhD, medical journalist

For the hard-to-treat patient with reflux disease, it is easier to use a wireless device although there is no improvement in outcome.
In gastroesophageal reflux disease (GERD) stomach acid flows back into the esophagus. The condition may respond to medication but it can also be hard to treat. In such cases, the acidity of stomach contents backwashed into the esophagus is monitored with a probe. This give a more accurate assessment of the problem.

The conventional way of monitoring involves the use of a probe attached to a catheter which is thread through the nose and down the throat. The probe stays for 24 hours, sending back information to a recorder which the patient must wear. Those using the probe complain of nose pain and throat discomfort.

Researchers at the Blue Cross and Blue Shield Association's Technology Evaluation Center looked at the conventional device versus a wireless version. The latter involves inserting a wireless probe to be fitted at the muscular valve at the bottom of the esophagus. Patients preferred the wireless version as it caused less interference in daily activities. But some complained of discomfort behind the breastbone. On outcomes, the wired and wireless device were similar. However, the wireless device might be worn for longer and may give more useful information. The team looked at this and found that data gathered over 48 hours did not seem more useful than that gathered over 24 hours.
