Predicting Outcomes of Gastric Peroral Endoscopic Myotomy Using a Gastric Electrical Mapping System: GPOEM-GEMS

Observational University of Auckland, New Zealand · NCT06381349

This study is testing if a new method called Gastric Alimetry can help predict how well a gastric procedure will work for people with gastroparesis.

What this trial studies

This observational study aims to assess the effectiveness of Gastric Alimetry in predicting the outcomes of gastric peroral endoscopic myotomy (GPOEM) for patients with gastroparesis. Participants will undergo a baseline Gastric Alimetry assessment and will be followed for 12 months post-procedure to evaluate their symptoms, quality of life, and health psychology. The study seeks to develop a clinical decision rule to improve patient selection for GPOEM. Data will be collected through standard protocols and follow-up assessments using the myCap app.

Who should consider this trial

Good fit: Ideal candidates for this study are adults aged 18 years or older who are indicated for GPOEM.

Not a fit: Patients who are pregnant, breastfeeding, or unable to perform the Gastric Alimetry test due to skin sensitivities or other health issues may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could enhance the selection process for GPOEM, leading to improved treatment outcomes for patients with gastroparesis.

How similar studies have performed: While the approach of using Gastric Alimetry is innovative, similar studies have not been widely reported, making this a potentially novel investigation.
