Establishment of Surgically Induced Chronic Acid Reflux Esophagitis in Rats

Abstract
Background: The purpose of the study was to establish an animal model of chronic acid reflux esophagitis which could be used for further investigations of the pathophysiology of reflux esophagitis. Methods: Esophagitis was produced by ligating the transitional region between the forestomach and the glandular portion with a 2-0 silk thread and covering the duodenum near the pylorus ring with a small piece of an 18Fr Né
