Demonstration of gastroesophageal reflux in children by radionuclide gastroesophagography.
Twenty-five infants and children with proved gastroesophageal reflux were studied by radionuclide gastroesophagography to determine its sensitivity in detecting reflux. Patients swallowed an inert radiotracer (Tc-99m sulfur colloid) and gamma camera images of the stomach and esophagus were made with and without abdominal pressure. The test was easy to perform and was well tolerated. Reflux was demonstrated in 20 patients (80%); this compared favorably with barium gastroesophagography.
