This study was designed to clarify whether a part of the variability in gastric emptying could be ascribed to a relationship between meal ingestion and phase activity of the migrating motor complex and whether reproducibility is increased when meal ingestion takes place in relation to preselected characteristics of the migrating motor complex. We examined 12 healthy males, and the design included three examinations, twice with meal ingestion in a duodenal Phase I, and once in a Phase II. The meal consisted of an omelette labelled with 99m Tc followed by 150 ml water labelled with 111 In. The results showed that liquid lag phase (min) and was significantly shorter in Phase II than in Phase I (1 vs. 4, P = 0.007). The half emptying time of solid linear phase (min) was reproduced with nearly identical median and range values in the three series (I[1]: 67[51–87]; I[2]: 63[47–80]; 61[47–76]). With meal ingestion in Phase I a significant difference between inter‐ and intra‐individual variance could not be demonstrated. With meal ingestion in Phase I a second examination in Phase I did not increase reproducibility of any of the variables compared to a second examination in Phase II. In conclusion, scientific investigations on gastric emptying have to be performed with phase related meal ingestion and a double‐radionuclide technique.
