简要总结
The purpose of this research study is to evaluate if an enhanced Enterra device programming strategy will improve symptoms associated with gastroparesis, improve symptoms in a faster amount of time, and improve quality of life measures.
Participants in this study will be evaluated for study entry criteria, have an Enterra Therapy System implanted, and be randomly assigned to one of two programming strategies. Participants will answer daily questions about their gastroparesis symptoms on an application with their phone/tablet. Participants will answer quality of life questionnaires about their gastroparesis symptoms at monthly study visits.
Participants will be involved in the study for up to six months after treatment assignment.
Programming parameters in the study are within currently approved labeling.

- •Patients with significant cardiac or cardiovascular disease, malignancy, or other conditions
- •Participation in other clinical studies
- •Use of narcotics more than three days per week or other drugs that may affect motility (e.g., Glucagon-like peptide 1 (GLP-1) agonist drug)
