Currently, a new generation of high-resolution electrogastrograms recording technology with 64-channel electrode array is being developed by Alimetry Limited. This BSGM provide a more complete understanding of the origin and propagation of human gastric slow-wave activity non-invasively, such as frequency, amplitude, velocity, and pattern, in high spatiotemporal detail. The system is also capable of providing a novel meal response metric, which might correlate with the gastric emptying time. The system includes an App for tracking patient-reported symptoms throughout the test.The aim of the present study is to assess and compare BSGM and breath-based gastric emptying parameters and to study the relation between BSGM and presence or severity of individual symptoms and clinical features.The investigators will perform a study in 100 subjects to record gastric bioelectrical activity by non-invasive multi-channel body-surface electrode arrays during gastric emptying breathing test.

---|---|---|---|---|
Primary | Validation of body surface gastric mapping for delayed gastric emptying | The correlation of electrogastrography abnormality (in percentage) and delayed gastric emptying (t 1/2, minutes) will be determined employing a regression method. | 30 minutes before the meal and 4 hours after having meal. | |
Secondary | To assess correlation between electrogastrography abnormality and upper gastrointestinal symptoms. | Visual analogue scale (VAS) score for gastrointestinal symptoms, including pain, nausea, vomiting, bloating and flatulence will be recoded during recording gastric electrophysiological activity. The correlation of electrogastrography abnormality (in percentage) and upper gastrointestinal symptoms severity will be determined employing a regression method. | 30 minutes before the meal and 4 hours after having meal. |
