Aim: To evaluate the technical failures of the Bravo pH test in a population with nonerosive gastroesophageal reflux disease.
Methods: Over the course of a year, we prospectively studied a population of 66 nonerosive reflux disease patients who received a Bravo pH test. The number and frequency of all technical failures were documented, quantified and analyzed.
Results: A total of 66 patients, with a mean age of 41.7 years, were studied. Technical failures occurred in 15.15% of the sample. The most frequent failures were due to poor data reception (4.5%), early dislodgement (4.5%) and capsule removal (6.1%).
Conclusion: The Bravo capsule pH test involves a low but non-negligible rate of technical problems, a fact that must always be considered by physicians.
