[Gastroesophageal reflux in children. A combined radiologic and scintigraphic study]
Insights
Gastroesophageal reflux in children is best detected using radionuclide scintigraphy, which is more accurate and safer than barium X-ray. This reliable screening test offers higher diagnostic value for pediatric gastroesophageal reflux.
Area of Science:
- Pediatric Gastroenterology
- Diagnostic Imaging
- Nuclear Medicine
Background:
- Gastroesophageal reflux (GE) is a common condition in children.
- Accurate diagnosis of GE reflux is crucial for effective management.
- Existing diagnostic methods have limitations in sensitivity and safety.
Purpose of the Study:
- To compare the diagnostic accuracy of barium meal X-ray and gastroesophageal scintigraphy in pediatric patients with suspected GE reflux.
- To evaluate the reliability and safety of scintigraphy as a screening tool for GE reflux in children.
Main Methods:
- A double-blind study involving 31 children examined for GE reflux.
- Comparison of barium meal X-ray and gastroesophageal scintigraphy findings.
- Intraluminal esophageal pH probe testing for cases with negative initial findings.
Main Results:
- Gastroesophageal scintigraphy detected GE reflux in 89% of patients, significantly higher than barium X-ray (63%).
- Combined use of both tests yielded positive findings in 96% of cases.
- Scintigraphy demonstrated superior diagnostic accuracy, ease of use in young patients, and lower radiation exposure compared to barium X-ray.
Conclusions:
- Gastroesophageal scintigraphy is a safe, reliable, and highly accurate screening test for diagnosing GE reflux in children.
- Scintigraphy offers significant advantages over barium X-ray for pediatric GE reflux evaluation.
Abstract:
Thirty-one children examined for gastroesophageal (GE) reflux were studied with both barium meal X-ray and gastroesophageal scintigraphy. The study was performed with a double-blind method. The children with negative findings at both tests were submitted to intraluminal esophageal pH probe test. Barium X-ray detected GE reflux in 17/27 patients, whereas radionuclide scintigraphy was positive in 24/27 (positivity: 63% versus 89%; p less than 0.05). Their combined use provided positive findings in 26/27 cases. Scintigraphy appeared to be a safe and reliable screening test to detect GE reflux. Moreover, scintigraphy was superior to barium X-ray study for it had higher diagnostic accuracy, it could be easily performed on young patients, and delivered smaller radiation doses.
