[Study on esophageal motility and its effect by EVL in patients with esophageal varices]
1Department of Gastroenterology, Yunnan First Provincial People's Hospital, Kunming.
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.
Conclusion:
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.
