Summary

The Gastroparesis Registry 4 (GpR4) is an observational study of patients with symptoms of gastroparesis (Gp) and functional dyspepsia (FD) with either delayed or normal gastric emptying. To better understand these disorders, this registry will capture demographic, clinical, physiological, questionnaire, and patient outcome data to characterize the patients and their clinical course. Participants will complete several questionnaires, complete a nutrient drink test and have a gastric emptying study.

Eligibility

Min Age: 18 YearsMax Age: 85 Years

Inclusion Criteria4

Age at least 18 years at initial screening visit
Symptoms of Gp and/or FD of at least 12-weeks duration with varying degrees of nausea, vomiting, early satiety, postprandial fullness, abdominal pain, abdominal burning. Thus, patients can enter the GpR4 registry primarily with abdominal pain suggesting FD-Epigastric Pain Syndrome.
Successful completion of gastric emptying scintigraphy of solids using the 4-hour Egg Beaters® protocol (or equivalent generic liquid egg white meal) within the last 9 months
Negative upper endoscopy or upper radiographic GI series within 5 years of registration

Exclusion Criteria14

Use of narcotic analgesics greater than three days per week
Presence of other conditions that could explain the patient's symptoms such as:

Active inflammatory bowel disease
Known eosinophilic gastroenteritis or eosinophilic esophagitis
Primary neurological conditions that can cause nausea and vomiting such as increased intracranial pressure, space occupying or inflammatory/infectious lesions

Prior gastric surgery including total or subtotal (near complete) gastric resection, esophagectomy, gastrojejunostomy, gastric bypass, gastric sleeve, pyloroplasty, pyloromyotomy, or any fundoplication (Nissen, Tor)
Any other condition, which in the opinion of the investigator, could explain the symptoms or interfere with study requirements
Females who are pregnant. A urine pregnancy test is routinely obtained on all females immediately prior to gastric emptying procedures.
