BACKGROUND/AIMS: The aim of this study was to evaluate the changes of electrogastrographic findings and gastric fullness before and after feeding rice soup in patients with dysmotility-like functional dyspepsia (DLFD). METHODS: The study was erformed on 87 patients with DLFD and 50 normal controls. Abdominal surface electrogastrography was applied for 30 min in the fasting state and for 30 min after feeding rice soup. RESULTS: Patients with DLFD showed higher scale of gastric fullness in fasting baseline and postprandial 30 min, comparing to normal controls. Significan differences were found between the patients with DLFD and normal controls in the percentage of fed 3 cpm slow waves, in the power ratio, and in the percentage of fed bradygastria and fed tachygastria In the percentage of fasting 3 cpm waves, the percentage of fasting bradygastria and fasting tachygastria, and the dominant frequency of either fasting or fed electrogastrography, the patients and the normal controls did not show difference. No correlation was found between the percentage of 3 cpm slow waves and the scale of gastric fullness. CONCLUSIONS: Patients with DLFD have a lowe percentage of normal gastric slow waves in the fed electrogastrography and have a lower power ratio
