一般认为食管内pH呈碱性的原因是由于碱性十二指肠液返流入食管所致。此外,唾液的pH也呈碱性。为了阐明食管内pH呈碱性的原因,作者观察了消化性食管炎患者7例,消化性食管狭窄患者8例,消化性食管炎和曾行Billroth Ⅱ型胃部分切除的患者7例。同时持续测定食管内和胃内的pH22小时。如胃内pH上升>7,而食管内pH同时也上升>7时,才认为发生了碱性胃、食管返流。 结果:消化性食管炎、消化性食管狭窄和Billroth Ⅱ型胃部分切除三组患者的食管内pH<4的时间百分比(X±SE)分别为
It is generally believed that the reason why the pH in the esophagus is alkaline is due to the return of alkaline duodenal fluid into the esophagus. In addition, the pH of saliva is also alkaline. To clarify why esophageal pH was alkaline, we observed 7 patients with gastroesophageal esophagitis, 8 patients with digestive esophageal stenosis, 7 patients with gastroesophageal esophagitis and patients undergoing partial gastric resection with Billroth type II gastric cancer. At the same time continuous determination of esophageal and gastric pH22 hours. Such as gastric pH increased> 7, while the esophageal pH also increased> 7, it was considered that the occurrence of alkaline stomach, esophageal reflux. Results: The time (%) of esophageal pH <4 in digestive esophagitis, digestive esophageal stenosis and Billroth Ⅱ partial gastrectomy were (X ± SE)
