1983年,作者赴西德作短期学习考察,现将了解到的有关消化病学临床研究方面的情况简介如下。食管疾病返流性食管炎的病因尚不很清楚,除由胃酸和胃蛋白酶引起的酸反流性食管炎外,近来更强调胆汁反流引起的碱反流性食管炎。胃酸分析及食管 pH测定对两者的鉴别有一定的意义。有人认为食管上皮内嗜酸性细胞浸润是酸反流性食管炎具有病理特征意义的改变。但 Janisch 等对此持否定意见。食管内压力测定证明,反流性食管炎有食管下端括约
In 1983, the author went to West Germany for a short study tour, and the briefings on the clinical research on digestive diseases that we have learned are as follows. Esophageal disease The etiology of reflux esophagitis is not well understood, except acid reflux and esophagitis caused by gastric acid and pepsin, the recent emphasis on bile reflux caused by alkaline reflux esophagitis. Gastric acid analysis and esophageal pH determination of the two have some significance. Some people think that esophageal epithelial eosinophilic infiltration is acid reflux esophagitis with pathological features of the change. But Janisch and others disagree. Esophageal pressure test proved that reflux esophagitis esophageal lower contract
