简要总结
This protocol is designed to validate use of the SPM for diagnosis of delayed gastric emptying in patients with symptoms of gastroparesis and assess impact of a SmartPill study on patient management in the gastroparetic populations. Patients with symptoms of gastroparesis will be recruited.
Patients will undergo concurrent gastric scintigraphy and SPM testing to determine the presence or absence of delayed gastric emptying based on predetermined diagnostic cutoffs for each technique.

- •1 Nausea, vomiting, or retching (dry heaves)
- •2 Postprandial fullness or early satiety
- •3 Bloating or visible abdominal distention
- •4 Postprandial discomfort or pain
- •Ability to stop proton pump inhibitors for 7 days and histamine2 receptor antagonists, prokinetic agents, narcotic agents, anticholinergic drugs, and cannabinoids 3 days prior to SPM and gastric scintigraphy testing.
- •No evidence of metabolic disease (hypothyroidism, uncontrolled diabetes [hemoglobin A1c >10% within the past 6 months], electrolyte imbalance).
- •An upper endoscopy or upper gastrointestinal barium series within the past 2 years showing no organic disease that is potentially causative of symptoms.
- •High probability of compliance and completion of study.
