What this trial studies

This observational study collects biopsy samples from patients diagnosed with gastroparesis who are undergoing gastric electrical stimulation implantation surgery. It also includes a control group of patients without gastroparesis undergoing various digestive surgeries. The study aims to investigate the underlying causes of motility disorders, assess symptom severity through questionnaires, and follow patients over 24 months to evaluate outcomes. The collected data will help direct future investigations and improve prognosis for patients with these conditions.

Who should consider this trial

Good fit: Ideal candidates include patients diagnosed with gastroparesis who are scheduled for surgical biopsy and those undergoing specific digestive surgeries without gastroparesis.

Not a fit: Patients with significant comorbidities, contraindications for biopsy, or prior diagnoses of gastroparesis may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to better understanding and management of gastroparesis, improving treatment options for patients.

How similar studies have performed: While similar studies have explored motility disorders, this specific registry approach focusing on biopsy samples is relatively novel.
