动态胃、食管双pH监测小儿胃食管反流

目的 判断小儿胃食管反流病（GERD）的类型，提高GERD的诊断率。方法 采用晶体锑双pH微电极对临床疑诊GERD患儿65例进行食管下段和胃底部pH值24h动态监测。结果 29例（44．6％）有酸性胃食管反流，4例（6．1％）有碱性胃食管反流，总检出率50．7％，两组各项反流指标与对照组相比差异有显著意义。结论 动态胃、食管双pH监测能较准确地判定反流的有无及其类型，并提高GERD的诊断率。

Monitoring gastroesophageal reflux in children with ambulatory double gastroesophageal pH

Objective To judge types of Gastroesophageal reflux disease(GERD) in children so as to improve the diagnosis of GERD.Methods Ambulatory 24 hour distal esophageal and gastric pH monitor was conducted in 65 cases of GERD with double pH probe.Results Acid GER was observed in 29 cases (44.6 %).Alkaline GER was observed in 4 cases (6.1 %), totally 33 cases (50.7 %). The parameters were significantly different in two groups than in controls.Conclusions Ambulatory double Gastroesophageal pH monitor can judge the extent and the type of reflux which is helpful in the diagnosis of GERD.
