title: [Radiological and manometric study of gastroesophageal reflux in normal infants].
abstract: The incidence of the gastroesophageal reflux was studied in 39 healthy infants with ages between 2 and 24 months. X-ray studies of gastroesophageal passage and esophageal manometry were practiced in all cases. Only 3 infants showed radiological reflux. The pressure in the gastroesophageal sphincter was normal in all babies and the highest pressures were reached less--than 6 months--old infants. Older infants showed lesser pressures. The same was true for the length of the gastroesophageal sphincter. The factors involved in the genesis of the gastroesophageal reflux are discussed.
