ABSTRACT
Objective To explore the relationship between acid pocket and acid reflux in gastroesophageal reflux disease (GERD).Methods From March 2011 to January 2012,29 patients with GERD were enrolled and nine healthy individuals were set as control.All objects of this study accepted esophageal manometry test,acid pocket test,test of the occurrence time of acid pocket and ambulatory 24 hours pH monitoring.The t-test was performed for comparison between two groups.The relationship between the incidence of GERD and acid pocket was analyzed by Logistic regression analysis.Pearson correlation analysis was used for correlation analysis.Results The percentage of acid pocket in GERD group and control group was 58.6% (17/29) and 5/9,respectively,and the difference was not statistically significantly (P>0.05).The duration time of acid pocket was (56.3±44.7) minutes in GERD group which was longer than that of control group ((16.0±8.2) minutes) and the difference was statistically significant (t=1.970,P<0.01).There was no statistical significance in the average pH value of acid pocket between GERD group with acid pocket (2.8 ± 1.3) and that of control group with acid pocket (1.9±0.5,P>0.05).The duration time of acid pocket was correlated with the longest reflux time in GERD group with acid pocket (r=0.550,P<0.01).The peak velocity of esophageal motility in GERD group ((3.3±0.6) cm/s) was lower than that of control group ((5.0±4.1) cm/s) and the difference was statistically significant (t=-1.354,P<0.05).The peak velocity of esophageal motility in GERD group with acid pocket ((3.2±0.6) cm/s) was lower than that of control group with acid pocket ((7.2± 6.3) cm/s) and the difference was statistically significant (t=-2.693,P<0.05).Conclusions The duration time of acid pocket in GERD is correlated with the time of acid reflux.Esophageal dysmotility may be related with the pathogenesis of GERD and the occurrence of acid pocket.
