- Brief Summary
This is a feasibility study to assess the utility of magnetically controlled capsule endoscopy in the evaluation of gastroparesis and functional dyspepsia
- Detailed Description
Gastroparesis and functional dyspepsia can both present with abdominal pain, dyspepsia, nausea, emesis, or early satiety. Gastroparesis is a syndrome defined as delayed gastric emptying. Functional dyspepsia is a symptom-based diagnosis in which the pathophysiology is multifactorial. Delayed gastric emptying is present in 25-35% of patients with functional dyspepsia. The study investigators propose the Navicam magnetically controlled capsule endoscopy (MCCE) system as a potential new method of evaluating gastric motility disorders. The MCCE is FDA approved for visualization of the stomach. The ability to visualize gastric peristalsis in real time, without interference from an endoscope, has never been demonstrated. The MCCE system could allow physicians to evaluate gastric motility with a test that has clear advantages over the current methods: it is fast, non-invasive, and has no radiation exposure, has artificial intelligence (AI) capabilities, while at the same time provides a visual assessment of the gastric anatomy. In this pilot feasibility study, the study investigators plan to enroll 5 male and female adult healthy volunteers, 5 male and female patients with gastroparesis, 5 male and female patients with functional dyspepsia (epigastric pain syndrome and/or postprandial distress syndrome with or without gastric emptying delay), and 2 patients with gastroparesis who have undergone a G-POEM procedure. The study investigators will compare gastric motor patterns in the different sections of the stomach and symptoms during fasting and a sham meal between groups.

- Use of prohibited medication or medication with anti-nausea, antiemetic, neuromodulating, or prokinetic effect within 2 weeks of the screening visit EXCEPT when administered on a stable daily dosing schedule (stable for at least 1 month prior to the screening visit).
- Use of as needed or daily opioids within the past 1 month.
- Pyloric injection of neurotoxins (e.g. botulinum type A or B) within 3 months of the Screening visit.
- Altered mental status (e.g., hepatic encephalopathy) that limits the ability to swallow a capsule
- Expected to have Magnetic Resonance Imaging (MRI) examination within 30 days.
- No reliable contact information - no phone, no permanent address.

- Prior bowel surgery
- Severe claustrophobia
- Any other reason as determined by the Investigator which may lead to an unfavorable risk-benefit of study participation, may interfere with study compliance, or may confound study results.
