H.pyIori除菌後に経験される「逆流性食道炎」,「十二指腸びらん」の発生病理 特に酸分泌能変化との関連について

摘要

The aims of this study were to investigate whether the changes in gastric acid secretion after H. pylori eradication might influence the development of acute duodenitis (AD) and reflux esophagitis (RE). Stimulated acid output was assessed by EGT(mEq/10rnin), which is the new endoscopic method of gastric secretory testing described previously. Changes in the EGT values before and after eradication were divided into 4 groups; decreased group, no change group, increased group, markedly increased group. Results estimated by EGT demonstrated that AD and RE development after eradication significantly correlated with the increase of acid secretion. In coclusion, the increase of acid secretion was thought to be one of the most important risk factors of both AD and RE developed after H. pylori eradication.
