[Diagnostic possibilities of intragastric pH-metry].

The data obtained during aspiration and intragastric pHmetry were studied and compared. Criteria of evaluating acid formation in the stomach were developed according to the intragastric pHmetry data. Examination of healthy subjects and patients with gastrointestinal diseases permitted one to distinguish the main types of secretion. It was demonstrated that intragastric pHmetry is not inferior, in the diagnostic aspect, to a classical aspiration study, while in a number of situations, it compares very favourably with this method of examination.
