Clinical Trial Summary

To check whether the first 12 hours of MII-pH recording are sufficient to diagnose gastroesophageal reflux disease (GERD) among newborns/infants, with a diagnostic accuracy similar to 24 hours of recording as currently advised.

Description:

The results of the 24 hour MII-pH recording will be compared to those from the first 12 hour of the same study. To this end the study investigators will select the first 12 hour of the recording using the manufacturer's software (Diversatek Zvu Advanced GI Diagnostic Software). Published normal reference values will be used to confirm gastroesophageal reflux (GER). Appropriate statistical methods will be used to perform calculations. Subgroup analyses based on preterm birth, presence of bronchopulmonary dysplasia and type of prevalent GER symptom (respiratory or gastrointestinal) will be performed.

Eligibility

Inclusion Criteria:

• 24 hours MII-pH performed for suspected GER

Exclusion Criteria:

• major malformations

• previous thoraco-abdominal surgery, gastrostomy, anti-GERD therapy (thickeners, alginates, H2 blockers, proton pump inhibitor - PPIs, etc.) in the 7 days preceding the MII-pH,

Related Conditions & MeSH terms

• Gastroesophageal Reflux

Intervention

Diagnostic Test:
• multichannel intraluminal impedance and pH monitoring (MII/pH)
A pH-MII probe is inserted nasally into the esophagus, and the position verified by chest radiograph. pH-MII data are evaluated using manufacturer's software, and each tracing is manually reviewed and validated.
