Background: Antroduodenal manometry (ADM) records lumen‐occluding contractions of the gastric antrum, while electrogastrography (EGG) measures gastric myoelectric activity using cutaneous electrodes placed on the abdominal wall. Under physiological conditions there is a temporal correlation between myoelectric slow waves and contractile activity of the antrum. It is unclear if there is also a spatial correlation between electric and contractile activity.Aim of the study: To determine the relationships between electrical activity measured by EGG and antral contractile activity measured by ADM.Material and methods: This is a retrospective analysis of patients with various motility disorders of the gut subjected to simultaneous ADM and EGG recording. A single bipolar channel measured the EGG and ADM was done using either 6 or 8 channels. EGG parameters analysed were: (i) percentage of time with a dominant frequency (DF) in normogastric (2–4 cpm), tachygastric (4–10 cpm) and bradygastric (0.5–2 cpm) frequency bands; (ii) EGG power attributed to the three frequency bands (normogastria, tachygastria and bradygastria); (iii) the ratio of postprandial to fasting power of the DF; (iv) the overall DF; (v) variability of the dominant frequency (DFIC) and (vi) variability of the dominant power (DPIC). The ADM parameters measured were: mean frequency and amplitude of contractions and the motility index. Data from one hour before and the first hour after a test meal were compared.Results: A total of 151 patients, 125 (83%) females, mean age 45 ± 14 years, were analysed. There were 52 patients with irritable bowel syndrome, 26 patients with slow transit constipation, 22 patients with enteric dysmotility, 11 patients with chronic intestinal pseudo‐obstruction and 13 patients with gastroparesis or functional dyspepsia, three patients with previous gastric surgery and 24 patients with other motility disorders of the gut. We found no relation between any of the 21 EGG parameters and eight ADM parameters. Comparison between EGG response to meal ingestion (ratio between postprandial and fasting power) and ADM response to meal ingestion (ratio between postprandial and fasting motility index) revealed no correlation (r = 0.06, p = 0.44).Conclusions: No spatial correlation was observed between EGG and ADM in this series of patients with motility disorders. EGG and ADM give different kinds of information.
