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.
对39名年龄在2至24个月之间的健康婴儿进行了胃食管反流发病率的研究。所有病例均进行了胃食管通道的X线检查和食管测压。只有3名婴儿显示有放射学上的反流。所有婴儿的胃食管括约肌压力均正常，压力最高值出现在6个月以下的婴儿中。年龄较大的婴儿压力较小。胃食管括约肌的长度情况也是如此。文中讨论了胃食管反流发生的相关因素。
