胃食管返流(Gastroesophageal reflux,GER)是婴幼儿顽固性呕吐和生长发育迟缓的重要原因,常见的并发症有返流性食管炎、食管狭窄、溃疡及因反复呕血所致的贫血。近年来研究证明GER与婴幼儿时期反复发作的肺炎、哮喘及支气管炎、窒息和婴儿猝死综合征(SIDS)都有密切关系。因此,能否对病理性GER早期作出准确诊断,从而及时得到治疗,已成为临床上一个不可忽视的重要课题。本文通过我院近年所收治20例临床资料的分析,结合文献对小儿GER的诊断进行讨论。0 Gastroesophageal reflux (GER) is an important cause of intractable vomiting and growth retardation in infants and young children. Common complications include reflux esophagitis, esophageal stricture, ulcer and anemia caused by repeated hematemesis. In recent years, studies have shown that GER and infants and young children recurrent pneumonia, asthma and bronchitis, asphyxia and sudden infant death syndrome (SIDS) are closely related. Therefore, the early diagnosis of pathological GER can be accurately diagnosed, and thus get timely treatment, has become an important clinical issue can not be ignored. This article through our hospital in recent years, 20 cases of clinical data analysis, combined with the literature on the diagnosis of pediatric GER are discussed. 0
