[A pH-probe for endoscopic parietal topographical pH-metry].
A pH-probe for endoscopic parietal topographical pH-metry was developed. The probe has a circular measuring electrode and a cutaneous silver chloride reference electrode. Clinical testing of the developed probe was performed to compare it with a conventional end electrode. It was found that the new pH-probe with circular antimonial electrode for pH measurement at the surface of the mucous coat of upper gastrointestinal tract in a fasting patient considerably increases the accuracy of pH measurement at the site of acid glands. Recommendations for examination of acid-forming and alkalizing functions of stomach and determination of the boundaries of the main regions of stomach during endoscopic examination are given.
