a Array placement in relation to the thoracoabdominal gastric conduit. b Coronal, sagittal and axial views from CT scans of ID#1 illustrating the location of the stomach located in the posterior mediastinum, behind the heart, lungs and liver. c Gastric Alimetry stretchable electrode array. d Gastric Alimetry wearable Reader. e Gastric Alimetry electrode array and wearable Reader on the patient’s thoracoabdominal region, per the placement depicted in a. f Spectral map for Case ID#1 illustrating a reduced principal gastric frequency and BMI-adjusted average amplitude. Patient photo and imaging are used with patient's written consent. AgCl, silver chloride; TPU, thermoplastic polyurethane.

Fig. 2
a–d illustrates case ID#2 to ID#5’s spectral maps with associated symptom burden plots. Quantitative analysis is presented in e with reference intervals as shown. Quantitative results for case ID#1 shown in Fig. 1f are also presented in e. f Spectrogram for the patient with the colonic interposition graft. g Box and whiskers graph for the quantitative results for case ID#1 to ID#5. The dashed line represents the lower limit of the reference interval for each Gastric Alimetry spectral metric. ff-AR, fed:fasted amplitude ratio; GA-RI, gastric alimetry rhythm index.
