Abstract:
Objective To explore the correlation between the length of peristaltic break (LPB) and the severity of the symptoms in patients with non-erosive reflux disease (NERD) and negative pH monitoring.Methods A total of 35 patients with NERD and negative pH monitoring were enrolled,and at same time 10 healthy individuals were selected as controls.The LPB of esophageal body of both groups was measured by high resolution manometry (HRM).Meanwhile,the symptom of NERD patients with negative pH monitoring was scored.The LPB of esophageal body between the two groups was compared by t test.The correlation between the LPB and the severity of the symptoms in NERD patients with negative pH monitoring was analyzed by Pearson correlation analysis.Results The average LPB of esophageal body of NERD patients with negative pH monitoring was (3.3±0.9)cm,which was longer than that of healthy controls ((1.2 ± 0.4) cm),and the difference was statistically significant (t=9.17,P＜0.01).The symptom score of NERD patients with negative pH monitoring was 21.6± 7.8.There was a positive correlation between the LPB and NERD symptom score (r=0.894,P＜ 0.01).Conclusion The LPB of esophageal body is a kind of expression of esophageal motility dysfunction,which is correlated with the symptom of NERD.
