Design outcomes

Primary

Measure	Time frame
Ease and use of body surface gastric mapping device measured using patient self-reported questionnaires at any point pre-operatively and repeated 3 to 6 months post-operatively	—

Secondary

Measure	Time frame
Captured electrical activity data measured using data from the device correlated with patient-reported outcomes measured using a Patient Reported Outcome Score Test (POST) and the Gastroesophageal Reflux Disease-Health Related Quality of Life (GORD-HRQL) questionnaires at any point pre-operatively and repeated 3 to 6 months post-operatively.	—
