The pH values in 203 patients with various gastroduodenal pathologies were measured by means of a glass electrode inserted into the bioptic channel of the gastroscope. Analysis of the results confirms what we know of pH variations in gastric or duodenal ulcer cases and shows where perendoscopic pH measurements may be used beneficially. In particular it was found that mucous pH is not affected by H2 antagonists if these are taken more that 12 hours before the examination. Perendoscopic pH measurement appears to be a valuable tool in screening stomach lesions at risk in cases of chronic gastritis, since it facilitates the identification of atrophic or metaplastic lesions.
通过插入胃镜活检通道的玻璃电极，对203例患有各种胃十二指肠疾病的患者的pH值进行了测量。结果分析证实了我们对胃溃疡或十二指肠溃疡病例中pH值变化的了解，并表明了内镜下pH测量可在哪些方面得到有益应用。特别值得注意的是，如果在检查前12小时以上服用H2拮抗剂，黏液pH值不受其影响。内镜下pH测量似乎是筛查慢性胃炎高危胃病变的一项有价值的工具，因为它有助于识别萎缩性或化生病变。
