1) Prospective study part: Patients with suspected LES dysfunction attending the Digestive Disease Center of Showa University Koto Toyosu Hospital who undergo esophageal endoscopy, barium angiography, or 24-hour pH test in addition to upper gastrointestinal endoscopy.
Retrospective study part: From December 5, 2020, until this study is approved by the Ethics Committee and the permission to conduct the study is obtained from the head of the implementing medical institution, patient information from the existing EPSIS study (approval number: UMIN000042661) that is applicable to this study will be used.
(2) Patients who are 20 years of age or older at the time of obtaining consent.
(3) Patients who have given their written consent to participate in this study.
Patients deemed ineligible at the discretion of the study physician

- Primary Outcome Measures
Name Time Method To measure the pressure waveform of EPSIS by oral and nasal endoscopy and to study the correlation <br>between EPSIS values by oral and nasal endoscopy.
- Secondary Outcome Measures
Name Time Method We will verify the usefulness of EPSIS by comparing the correlation between EPSIS pressure waveforms and subjective symptoms and disease severity, as well as the results of various tests (blood tests, pH monitoring, esophageal manometry, barium angiography, upper gastrointestinal endoscopy, etc.) performed on each subject. We will also measure the pressure waveform of EPSIS during gastric inversion and progressive insufflation, and compare the results with those of oral and nasal endoscopy, respectively.
