Abstract
A method for diagnosing gastro esophageal reflux disease (GERD), comprising: introducing an endoscope into a stomach of a subject; measuring a pressure in the stomach while supplying gas into the stomach using the endoscope; and determining whether the subject has GERD or not based on a maximum value of the pressure and a wave pattern of a value of the pressure.
Claims20
A method for diagnosing gastro esophageal reflux disease (GERD), comprising:
- inserting an endoscope into a stomach of a subject;
- supplying gas into the stomach of the subject;
- measuring an internal pressure within the stomach of the subject while supplying gas into the stomach of the subject using the endoscope to obtain a waveform of time-series change of the internal pressure value of the subject;
- obtaining a target waveform of time-series change of the internal pressure in the stomach of the subject;
- and
- comparing at least the target waveform of time-series change to at least a reference waveform of time-series change of an internal pressure within a stomach of a person without GERD.

A method for diagnosing gastro esophageal reflux disease (GERD), comprising:
- inserting an endoscope into a stomach of a subject;
- supplying gas into the stomach of the subject;
- measuring an internal pressure within the stomach of the subject while supplying gas into the stomach of the subject using the endoscope to obtain a waveform of time-series change of the internal pressure value of the subject, the waveform including a maximum value or around a maximum value of the internal pressure in the stomach of the subject;
- and
- comparing the maximum value of the subject to a threshold value of an internal pressure within a stomach of the person without GERD, wherein the threshold value is defined by identifying an internal pressure of time-series change within a stomach of the person without GERD.

A method for diagnosing gastro esophageal reflux disease (GERD), comprising:
- identifying a threshold value of an internal pressure within a stomach of a person without GERD;
- identifying a reference waveform of time-series change of the internal pressure within the stomach of the person without GERD, wherein the first waveform of time-series change increases to the threshold value when gas is supplied into the stomach;
- inserting an endoscope into a stomach of a subject;
- supplying gas into the stomach of the subject;
- measuring an internal pressure within the stomach of the subject while supplying gas into the stomach of the subject using the endoscope to obtain a waveform of time-series change of the internal pressure value of the subject, the internal pressure including a maximum value of the internal pressure in the stomach of the subject;
- obtaining a target waveform of time-series change of the internal pressure value in the stomach of the subject;
- comparing the maximum value of the subject to the threshold value of the person without GERD;
- and
- comparing the target waveform of time-series change to the reference waveform of time-series change.
