胃食管双pH监测小儿十二指肠胃食管返流

采用胃、食管双ｐＨ电极对２１例１～１２个月小儿进行２４ｈｐＨ值监测。７例无返流小儿为对照组，１４例有返流的小儿中９例为酸性返流（６４％），５例（３６％）为碱性返流即十二指肠胃食管返流（其中４例合并酸性返流）。碱性返流可引起严重的食管病变。传统的单一食管下端ｐＨ监测难以作出准确诊断，增加胃底ｐＨ监测为准确判定返流，特别是十二指肠胃食管返流提供重要根据，对于提高胃食管返流诊断率和指导临床对不同类型的返流进行有效治疗具有重要意义。

Gastroesophageal Double pH Monitoring in Children with Duodenogastroesophageal Reflux

Twenty-four hour monitoring of gastroesophageal double pH was performed on 14 infants with reflux and 7 cases without reflux as control. According to the value of pH, they were grouped under : 1) acid reflux(9) , 2) alkaline reflux ( 1 ) ,3) mixed reflux (acid-alkaline 4).The double pH monitoring will make the diagnosis more accurate and guide the antireflux treatment more efficient. especially for duodenogastroesophageal reflux (alkaline reflux) .
