About this trial

The purpose of this study is to investigate whether or not the investigators can utilize Body Surface Gastric Mapping to determine who would best benefit to receive G-POEM procedure and how Body Surface Gastric Mapping can be utilized with patients who have gastroparesis symptoms. the investigators may also be able to find more ways how Body Surface Gastric Mapping testing can benefit patients with gastroparesis and/or G-POEM procedure.

Eligibility criteria

This trial does not accept healthy volunteers

Qualifiers

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

Disqualifiers

• 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

Trial outcomes

Primary outcomes

1

Body Surface Gastric Mapping Rhythm IndexTM (GA-RI)

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.

Time frame
Baseline, 3 months,6 months, up to 5 hours.
2

Principal Gastric Frequency

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

Time frame
Baseline, 3 months,6 months, up to 5 hours.
3

BMI-Adjusted Amplitude (μV)

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

Time frame
Baseline, 3 months,6 months, up to 5 hours.
4

Fed: Fasted Amplitude Ratio (ff-AR)

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.

Time frame
Baseline, 3 months,6 months, up to 5 hours.

Secondary outcomes

1

Body surface gastric mapping (BSMG)

enables accurate cutaneous gastric bioelectrical recording and provides valuable insights into the pathophysiology of gastric dysmotility in addition to gastric emptying measurements

Time frame
Baseline, 3 months,6 months, up to 5 hours.
