Intragastric pressure/volume relationship in the normal human stomach.
Intragastric pressure/volume relationship was studied twice in 8 healthy volunteers. Basal pressure and rhythmic contractile activity in response to defined volume loads were recorded. Reproducibility and precision of the parameters were evaluated. It is concluded that recording of the intragastric pressure/volume relationship is a valuable method for the evaluation of gastric motility, and it is well suited for clinical application. It is harmless and easy to perfrom. The reproducibility of the method and the precision of the parameters used are satisfactory.
