Abstract Objective To evaluate the application value of 24 h MII-pH monitoring in the diagnosis of gastroesophageal reflux disease (GERD). Methods Three hundred and twenty-six cases of GERD treated in our hospital from January 2016 to December 2018 were selected as the observation group, and 75 healthy volunteers were selected at the same time as the control group, all of which were monitored by 24 h MII-pH, and the related parameters of GERD were recorded. Comparison of MII-pH monitoring and pH monitoring in the diagnosis of GERD. Results ① 24 h pH monitoring results show that the observation group each monitoring indexes were significantly higher than those of the control group (P<0.05). ② 24 h MII-pH monitoring results show that in addition to weakly alkaline reflux times in two groups had no significant difference (P>0.05), other indicators of the observation group were significantly higher than those of the control group (P<0.05); ③ The positive rate of 24 h MII-pH monitoring in GERD was 87.42%, and the positive rate of pH monitoring was 44.78%, the difference was significant (P<0.05). Conclusion MII-pH can identify the direction of movement, acid-base properties and component of refluxate, and improve the detection rate of GERD, which has important clinical value.
