Body Surface Gastric Mapping for Gastroparesis and G-POEM

This study is looking at how a medical device called the Gastric Alimetry System, which uses electrodes on your skin to measure stomach activity (Body Surface Gastric Mapping), can help people with gastroparesis. Gastroparesis is a condition where your stomach empties food too slowly. Researchers want to see if this mapping can help predict who will benefit most from a procedure called G-POEM (Gastric peroral endoscopic myotomy), which helps improve stomach emptying. They also want to understand how Body Surface Gastric Mapping can be used to track how well G-POEM works and potentially find new ways to help patients with gastroparesis. You may be eligible if you are an adult who is a candidate for G-POEM at the study center and are not pregnant or breastfeeding. This study is currently unclear on its recruitment status and plans to enroll 20 participants.

Study design
This is an interventional study, meaning participants will receive a specific intervention. It aims to enroll 20 participants.
What's involved
You will have Body Surface Gastric Mapping measurements taken at the start of the study, and then again at 3 and 6 months. Each measurement session will last up to 5 hours.
Compensation
Not stated in the trial record.
Follow-up
Participants will be followed for 6 months after the start of the study, with measurements taken at 3 and 6 months.

Eligibility criteria

Inclusion

• Patients clinically eligible for G-Poem at our center.

Exclusion

• Pregnant or breast-feeding
Patients with gastroparesis due to spinal cord injuries due to difficulties in conducting the BSGM. Of note, we rarely see gastroparesis in this context.
Inability to perform BSGM: history of severe skin allergies or sensitivity to cosmetics or lotions; chronically damaged or vulnerable epigastric skin (fragile skin, wounds, inflammation); patients unable to remain in a relaxed reclined position for the test duration.
Patients with abdominal drains or tubes

What this trial measures

  • Body Surface Gastric Mapping Rhythm IndexTM (GA-RI)Baseline, 3 months,6 months, up to 5 hours.

    A measure of the concentration of amplitude in the gastric frequency band over time (between 0 and 1), which characterizes the rhythmic stability of the recorded gastric activity; also adjusted for BMI.

  • Principal Gastric FrequencyBaseline, 3 months,6 months, up to 5 hours.

    Characterizes the frequency associated with stable, persistent gastric activity as defined by GA-R

  • BMI-Adjusted Amplitude (μV)Baseline, 3 months,6 months, up to 5 hours.

    characterizes the strength of the recorded gastric activity as an average of the whole-test amplitude, adjusted for BMI

  • Fed: Fasted Amplitude Ratio (ff-AR)Baseline, 3 months,6 months, up to 5 hours.

    characterizes the responsiveness to a meal stimulus, which is calculated as a ratio of the maximal 1-h average postprandial amplitude to the amplitude in the preprandial period.

  • SF-36Baseline, 3 months,6 months, up to 5 hours.

    a set of generic, coherent, and easily administered quality-of-life measures
