What this trial studies

This clinical trial compares the effectiveness of endoscopic per-oral pyloromyotomy (POP) against a control sham intervention in adults suffering from medically refractory gastroparesis. Participants will be randomly assigned to receive either the POP procedure or a diagnostic esophagogastroduodenoscopy (EGD) without pyloric disruption. The study aims to evaluate improvements in gastric emptying and associated symptoms after the intervention. Eligible patients must have previously failed dietary, lifestyle, and pharmacological treatments for at least six months.

Who should consider this trial

Good fit: Ideal candidates are adults aged 18-75 with a diagnosis of medically refractory gastroparesis who have not responded to standard treatments.

Not a fit: Patients who have not been diagnosed with medically refractory gastroparesis or those who have not undergone prior medical management may not benefit from this study.

Why it matters

Potential benefit: If successful, this procedure could significantly improve gastric emptying and alleviate symptoms for patients with refractory gastroparesis.

How similar studies have performed: Other studies have shown promise with similar endoscopic approaches, suggesting potential for success in this trial.
