What this trial studies

This clinical trial evaluates the effectiveness of two treatment options, G-POEM and PEG-J, for patients suffering from refractory gastroparesis. It involves a randomized, non-blinded controlled design with two groups: one receiving G-POEM and the other receiving PEG-J. Treatment success will be assessed using the Gastroparesis Cardinal Symptom Index (GCSI) at baseline and six months post-intervention, with a potential crossover after the follow-up period. The study aims to enroll 50 patients who have not responded to standard dietary and pharmacological treatments.

Who should consider this trial

Good fit: Ideal candidates are adults aged 18 and older with diagnosed gastroparesis who have not responded to conventional therapies.

Not a fit: Patients under 18, those with a history of specific stomach surgeries, or current opioid users may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could provide a new effective treatment option for patients with refractory gastroparesis.

How similar studies have performed: Other studies have shown promising results with G-POEM for gastroparesis, indicating potential for success in this approach.
