What this trial studies

This randomized sham-controlled trial aims to evaluate the efficacy and safety of G-POEM, a novel endoscopic procedure, in patients suffering from diabetic gastroparesis. The study will involve a single-center, double-blinded design where participants will be randomly assigned to receive either the G-POEM intervention or a sham procedure. Prior to randomization, patients will undergo a meal test to assess their metabolic response and incretine hormone levels. The trial will include five study visits and a follow-up period of 90 days to monitor symptoms and any adverse events.

Who should consider this trial

Good fit: Ideal candidates include adults over 18 with a diagnosis of diabetic gastroparesis confirmed by technetium-scintigraphy.

Not a fit: Patients with ongoing cancer treatment, recent gastrointestinal surgery, or other significant health issues may not benefit from this study.

Why it matters

Potential benefit: If successful, this treatment could significantly improve symptoms and quality of life for patients with diabetic gastroparesis.

How similar studies have performed: While the G-POEM approach is relatively novel, similar endoscopic interventions have shown promise in treating other gastrointestinal motility disorders.
