High Resolution Gastric Mapping and Gastroduodenal Manometry

Sponsor: Mayo Clinic

Summary

Dyspepsia is a common problem attributed to gastric sensorimotor dysfunctions ie, delayed, or less frequently rapid gastric emptying (GE), impaired gastric accommodation, and increased gastric sensation. Therapeutic options manage symptoms, and there is no FDA approved medical therapy for dyspepsia. There is a need for better objective understanding of sensorimotor dysfunction in dyspepsia, as well as noninvasive, efficacious, safe, and inexpensive treatments for dyspepsia. The purpose of this research is to identify disturbances and characterize phenotypes in patients with functional dyspepsia, and to assess the correlations between symptoms (during the manometry and in daily life), gastric emptying, electrical activity (BSGM), and pressure activity (manometry).

Official title: An Assessment of Gastrointestinal Function Utilizing High Resolution Gastric Mapping, Gastroduodenal Manometry, and Gastric Emptying Testing With Assessment of Acute Response to Transcutaneous Auricular Vagal Nerve Stimulation.
