To verify the exact relation between electrical activity and gastric emptying 11 healty volunteers underwent cutaneous electrogastrography (EGGc) and ultrasonographic study of gastric emptying (GE) at baseline and at 30 min intervals after the ingestion of a mixed meal. Ratios of postprandial/baseline EGGc power and frequency (PR and FR, respectively), and ratios of gastric antrum area/basal value (AR) were calculated for the corresponding intervals. The final emptying time (mean ± SD) was 319 ± 49.03 min. The EGGc PR and gastric AR followed a similar time course after the meal. There was a statistically significant correlation between gastric AR and EGGc PR in nine subjects (p <0.05), but there was no correlation between AR and gastric ER. The finding that EGGc power is correlated with the cross-sectional area of the gastric antrum suggests that in the future a clinical use of EGGc may be possible.
