Twenty-four hour exophageal pH monitoring in gastroesophageal reflux
Insights
Twenty-four hour pH monitoring accurately assesses pediatric gastroesophageal reflux (GER). Esophagitis risk correlates with reflux duration, emphasizing esophageal acid clearance importance for identifying children needing surgical intervention.
Area of Science:
- Pediatric Gastroenterology
- Diagnostic Techniques
Background:
- Gastroesophageal reflux (GER) is common in children.
- Accurate diagnostic tools are crucial for managing GER and preventing complications.
Purpose of the Study:
- To evaluate the utility of 24-hour esophageal pH monitoring in pediatric GER.
- To establish normal pH monitoring patterns in children.
- To compare pH monitoring with other diagnostic methods.
Main Methods:
- 123 children aged 6 months to 6 years with GER underwent 24-hour esophageal pH monitoring.
- A modified scoring system was used to evaluate reflux.
- Normal patterns were established in a control group of 20 children.
Main Results:
- 24-hour pH monitoring is more objective, precise, sensitive, and reliable than contrast studies, endoscopy, or acid perfusion tests.
- Esophagitis appears to be more dependent on reflux duration than frequency.
- Esophageal acid clearance is a critical factor.
Conclusions:
- 24-hour pH monitoring is a valuable tool for diagnosing and managing pediatric GER.
- Understanding reflux duration and esophageal acid clearance aids in risk stratification and surgical selection.
- Further experience with this technique can improve identification of children at risk for severe complications.
Abstract:
Twenty-four hour pH esophageal monitoring has been studied in 123 children with gastroesophageal reflux (GER) with ages ranging between 6 mo to 6 yr. The technique is described and the scoring system modified to evaluate gastroesophageal reflux in these patients. For the first time the normal patterns are presented in pediatrics (n = 20). The results obtained in 103 patients are presented, divided into pre- and post-nonoperative and surgically treated groups. The test is more objective, has greater precision, sensitivity, and reliability than contrast studies, endoscopy, acid perfusion or acid reflux tests. The study seems to indicate that esophagitis depends more on the duration of the reflux than on the number, for which the concept of esophageal acid clearance is of paramount importance. The prone position generally lessens the number of refluxes but in this position the esophageal acid clearance is altered. With a greater knowledge and more experience in this technique, we would be able to identify children at risk to develop severe complications, control them and aid in the selection of those patients requiring surgical intervention.
