[Study on esophageal motility and its effect by EVL in patients with esophageal varices].
OBJECTIVE
To investigate the esophageal motility and its effect by EVL in patients with cirrhotic esophageal varices.


METHODS
LESP, LESR, PA, PD, PV and 24 h pH-monitoring were measured by PC Polygraf HR system in subjects of control and cases of esophageal varices before and after EVL.


RESULTS
In varices group, PA, PD, and PV were significantly abnormal in comparison with those in control group (P < 0.001, 0.01, 0.01). There were pathologic acid-reflux in patients with esophageal varices. After EVL, PA, PV and acid-reflux were significantly recovered.


CONCLUSIONS
Patients with esophageal varices suffer from the significant abnormal esophageal motility and acid-reflux. All of the abnormal changes can be recovered by EVL treatment.
